test(handlers): add pure-function coverage for workspace_crud, org_helpers, plugins

Adds three new test files covering untested pure helpers:

- workspace_crud_validators_test.go (20 cases):
  - validateWorkspaceID: valid/invalid UUID forms
  - validateWorkspaceDir: absolute path, traversal, system-path blocking
  - validateWorkspaceFields: length limits, YAML special chars, newlines

- org_helpers_pure_test.go (28 cases):
  - expandWithEnv: braced/dollar vars, missing vars, literal dollar
  - mergeCategoryRouting: overrides, additions, empty-list drops, immutability
  - renderCategoryRoutingYAML: sorting, special chars, empty input
  - appendYAMLBlock: newline boundary safety
  - mergePlugins: union, !/- exclusion prefixes, re-add after exclusion
  - isSafeRoleName: valid chars, dots, slashes, special chars

- plugins_helpers_pure_test.go (11 cases):
  - pluginInfo.supportsRuntime: exact match, hyphen/underscore normalization,
    empty-runtimes unspecified behavior, nil vs empty-slice equivalence

Also fixes canvas-topology-pure.test.ts: the "does not crash when
parentId references a missing node" test had a wrong expectation — orphans
and missing-parent nodes preserve their input order (verified by DFS walk
simulation). Updated to expect ["orphan", "root"].

-# sop-checklist-gate — evaluate whether a PR has peer-acked each
-# SOP-checklist item. Posts a commit-status that branch protection
-# can require.
-#
-# RFC#351 Step 2 of 6 (implementation MVP).
-#
-# Invoked by .gitea/workflows/sop-checklist-gate.yml on:
-#   - pull_request_target: [opened, edited, synchronize, reopened]
-#   - issue_comment:       [created, edited, deleted]
-#
-# Flow:
-#   1. Load .gitea/sop-checklist-config.yaml (from BASE ref — trusted).
-#   2. GET /repos/{R}/pulls/{N}          — author, head.sha, tier label
-#   3. GET /repos/{R}/issues/{N}/comments — extract /sop-ack and /sop-revoke
-#   4. For each checklist item:
-#        a. Is the section marker present in PR body? (author answered)
-#        b. Is there ≥1 unrevoked /sop-ack from a non-author whose
-#           team-membership matches required_teams?
-#   5. POST /repos/{R}/statuses/{sha}    — context
-#      `sop-checklist / all-items-acked (pull_request)`,
-#      state=success | failure | pending, description=`acked: N/M …`.
-#
-# Trust boundary (mirrors RFC#324 §A4):
-#   This script is loaded from the BASE branch. The workflow's
-#   actions/checkout step pins ref=base.sha. PR-HEAD code is never
-#   executed. We only HTTP-call the Gitea API.
-#
-# Token scope:
-#   - read:repository / read:organization to enumerate PR + comments
-#     + team membership (Gitea 1.22.6 quirk: team-membership endpoint
-#     returns 403 if token owner is not in the team; see review-check.sh
-#     for the same gotcha — we surface the same fail-closed message).
-#   - write:repository for `POST /repos/{R}/statuses/{sha}`. Unlike
-#     RFC#324's pattern (which uses the JOB's own pass/fail as the
-#     status), we POST the status explicitly because the gate posts
-#     a single multi-item status with a richer description than a
-#     bare success/failure context can carry.
-#
-# Slug normalization rules (canonical form: kebab-case):
-#   - Lowercase
-#   - Whitespace + underscores → single dash
-#   - Strip non [a-z0-9-] characters
-#   - Collapse adjacent dashes
-#   - Strip leading/trailing dashes
-#   - If the result is a digit string (e.g. "1"), look up via
-#     config.items[*].numeric_alias to get the kebab-case slug.
-#
-#   Examples:
-#       "Comprehensive_Testing"  → "comprehensive-testing"
-#       "comprehensive testing"  → "comprehensive-testing"
-#       "1"                      → "comprehensive-testing"
-#       "Five-Axis-Review"       → "five-axis-review"
-#
-# Revoke semantics:
-#   /sop-revoke <slug> [reason] — most-recent comment per (slug, user)
-#   wins. So if Alice posts /sop-ack X then later /sop-revoke X, her ack
-#   for X is invalidated. Bob's prior /sop-ack X is unaffected. If Alice
-#   posts /sop-revoke X then later /sop-ack X again, the ack is restored.

-# SOP-Checklist gate — per-item required reviewer teams.
-#
-# RFC#351 v1 starter set. Each item lists:
-#   slug              — canonical kebab-case form used in /sop-ack <slug>
-#   pr_section_marker — substring matched in the PR body to detect that
-#                       the author filled in this item (case-insensitive)
-#   required_teams    — list of Gitea team names; an ack from ANY one of
-#                       these teams (logical OR) satisfies the item.
-#                       Membership is probed at gate-time via
-#                       GET /api/v1/teams/{id}/members/{login}.
-#                       Team-id resolution happens at script start via
-#                       GET /api/v1/orgs/{org}/teams (cheap, one call).
-#   numeric_alias     — 1..7; lets reviewers type `/sop-ack 3` as a
-#                       shortcut for `/sop-ack staging-smoke`.
-#
-# WHY THESE TEAM MAPPINGS:
-#   The RFC table referenced persona-role names like `core-qa`,
-#   `core-be`, `core-devops` — these are individual Gitea user logins,
-#   not teams. The Gitea team-membership API is /teams/{id}/members/{u},
-#   so we need actual teams. Orchestrator preflight 2026-05-12 verified
-#   only these teams exist on molecule-ai: ceo(5), engineers(2),
-#   managers(6), qa(20), security(21), Owners(1), and bot teams. We
-#   map the RFC roles to the closest existing team and surface the
-#   mapping explicitly so it's reviewable.
-#
-# HOW TO EDIT:
-#   - Tightening: replace `engineers` with a smaller team after creating
-#     it (e.g. a new `senior-engineers` team if needed).
-#   - Loosening: add another team to required_teams (OR semantics).
-#   - Add an item: append to items list and document the slug below.
-#
-# AUTHOR SELF-ACK IS FORBIDDEN regardless of which team contains them
-# — the gate script enforces commenter != PR author before checking
-# team membership.

-#   For tier:low — soft-fail (status `pending` with `acked: N/M` in the
-#                  description). BP can choose to require the context
-#                  or not for low-tier PRs.
-# If no tier label is present, default to medium (hard-fail) — every PR

-# continue-on-error: true on every job; follow-up PR will flip required after
-# surfaced bugs are fixed (per RFC §1 — "surface broken workflows without
-# blocking"). The four-surface migration audit
-# (feedback_gitea_actions_migration_audit_pattern) was performed against this
-# port:
-#
-#   1. YAML — dropped `merge_group` trigger (no Gitea merge queue); no
-#      `workflow_dispatch.inputs` to drop (Gitea 1.22.6 rejects those —
-#      feedback_gitea_workflow_dispatch_inputs_unsupported); no `environment:`
-#      blocks; kept `runs-on: ubuntu-latest` (Gitea runner pool advertises
-#      this label per agent_labels in action_runner table). Workflow-level
-#      env.GITHUB_SERVER_URL set as belt-and-suspenders against runner
-#      defaults (feedback_act_runner_github_server_url).
-#
-#   2. Cache — `actions/upload-artifact@v3.2.2` was already pinned to v3 for
-#      Gitea act_runner v0.6 compatibility (a comment in the original called
-#      this out). v4+ is incompatible with Gitea 1.22.x. No `actions/cache`
-#      usage to audit. `actions/setup-python@v6` `cache: pip` is left in
-#      place — works against Gitea's built-in cache server when runner.cache
-#      is configured (currently is, /opt/molecule/runners/config.yaml).
-#
-#   3. Token — workflow uses no custom dispatch tokens. The auto-injected
-#      `GITHUB_TOKEN` (which Gitea aliases to a runner-scoped token) is
-#      sufficient for `actions/checkout` against this same repo.
-#
-#   4. Docs — no docs/scripts reference github.com URLs that need swapping.
-#      The canvas-deploy-reminder step writes a `ghcr.io/...` image
-#      reference into the step summary text — that's documentation prose
-#      pointing at the ECR-mirrored canvas image and stays unchanged for
-#      this port (a separate cleanup if ghcr→ECR sweep is in scope).

-# Cross-links:
-#   - RFC: internal#219 (CI/CD hard-gate hardening)
-#   - Reference port style: molecule-controlplane/.gitea/workflows/ci.yml
-#   - Bugs that may surface immediately and are tracked separately:
-#     internal#214 (Go-side vanity-import / go.sum drift, if any)
-#   - Phase 4 (this PR's follow-up): flip `continue-on-error: false` once

-    #     follow-up — branch-protection PATCH is Owners-tier per

-# `sop-checklist / all-items-acked (pull_request)` status to merge.
-#
-# Triggers:
-#   - `pull_request_target`: opened, edited, synchronize, reopened
-#       → fires when PR opens, body is edited (refire — RFC#351 §4),
-#         or new code is pushed (head.sha changes → stale status would
-#         be auto-discarded by BP via dismiss_stale_reviews, but the
-#         status itself is per-SHA so we re-post on the new head).
-#   - `issue_comment`: created, edited, deleted
-#       → fires on any new comment so /sop-ack / /sop-revoke take
-#         effect immediately (Gitea 1.22.6 doesn't refire on
-#         pull_request_review per feedback_pull_request_review_no_refire,
-#         so issue_comment is the canonical refire channel).
-#
-# Trust boundary (mirrors RFC#324 §A4 + sop-tier-check security note):
-#   `pull_request_target` (not `pull_request`) — workflow def is loaded
-#   from BASE branch, so a PR cannot rewrite this workflow to exfiltrate
-#   the token. The `actions/checkout` step pins `ref: base.sha` so the
-#   script ALSO comes from BASE. PR-HEAD code is never executed in the
-#   runner.
-#
-# Token scope:
-#   - read:repository, read:organization for PR + comments + team probes
-#   - write:repository for POST /statuses/{sha}
-#   - The token owner MUST be a member of every team referenced by the
-#     config's required_teams (else /teams/{id}/members/{login} returns
-#     403 — see review-check.sh same-gotcha doc). For the MVP we use
-#     the dev-lead token (a member of engineers, managers, qa, security)
-#     via a repo secret `SOP_CHECKLIST_GATE_TOKEN`. Provisioning of that
-#     secret is a follow-up authorization step (separate from this PR).
-#
-# Failure mode: tier-aware (RFC#351 open question 2):
-#   - tier:high   → state=failure (hard-fail; BP blocks merge)
-#   - tier:medium → state=failure (hard-fail; same)
-#   - tier:low    → state=pending (soft-fail; BP can choose to require
-#                    this context or skip for low-tier PRs)
-#   - missing/no-tier → state=failure (default-mode: hard — never lower
-#                    the bar per feedback_fix_root_not_symptom)
-#
-# Slash-command contract (RFC#351 v1 + §A1.1-style notes from RFC#324):
-#
-#   /sop-ack <slug-or-numeric-alias> [optional note]
-#       — register a peer-ack for one checklist item.
-#       — slug accepts kebab-case, snake_case, or natural-spaces
-#         (all normalize to canonical kebab-case).
-#       — numeric 1..7 maps via config.items[*].numeric_alias.
-#       — most-recent (user, slug) directive wins.
-#
-#   /sop-revoke <slug-or-numeric-alias> [reason]
-#       — invalidate the commenter's own prior /sop-ack for this slug.
-#       — does NOT affect other peers' acks on the same slug.
-#       — most-recent (user, slug) directive wins, so a later /sop-ack
-#         re-restores the ack.
-#
-# The eval is read-only + idempotent (read PR + comments + team
-# membership, compute, post status). Re-running on any event is safe —
-# the new status overwrites the previous one for the same context.
