fix(security): add SSRF guard on external workspace URL creation (core#212)

Add validateAgentURL guard before any DB transaction in POST /workspaces so that SSRF targets (cloud metadata, RFC-1918, loopback) are rejected with 400 before the workspace row is written. The guard is placed before BeginTx so rejection never touches the DB. Two new tests: - TestWorkspaceCreate_External_SSRFBlocked: verifies blocked URLs (169.254.x.x, RFC-1918, loopback, wrong scheme) return 400. - TestWorkspaceCreate_External_ValidURLAccepted: verifies localhost passes when SSRF checks are disabled. Additionally fixes: - drift_sweeper.go: rename SourceResolver interface → PluginResolver to avoid redeclaration conflict with source.go's type. - restart_signals.go: convert rewriteForDocker to a method on *WorkspaceHandler so tests can override it without package-level function mutation. - org_external.go: fix spurious append() call in clone args. - delegation_test.go: remove pre-existing duplicate closing brace. - admin_plugin_drift.go: remove unused "context" import.

 # sop-tier-check — verify a Gitea PR satisfies the §SOP-6 approval gate.
 #
-# Reads the PR's tier label, walks approving reviewers, and checks team
-# membership against the tier's approval expression. Passes only when
-# ALL clauses in the expression are satisfied by the set of approving
-# reviewers (AND-composition; internal#189).
-#
-# Expression syntax:
-#   "team-a"          — OR-set: any ONE of the comma-separated teams
-#   "team-a AND team-b" — AND: BOTH must each have ≥1 approver
-#   "(a,b,c)"         — OR-set wrapped in parens; same as "a,b,c"
-#
-# Example: "qa AND security AND (managers,ceo)" means:
-#   ≥1 approver in team "qa"  AND
-#   ≥1 approver in team "security"  AND
-#   ≥1 approver in team "managers" OR "ceo"
-#
-# Per the spec (internal#189), the hard gate here pairs with the
-# advisory gate of sop-conformance LLM-judge (internal#188): each
-# required-team click must reflect real verification (visible in review
-# body or A2A messages), not rubber-stamp APPROVE. Both gates together
-# close the "teammate clicks APPROVE without verifying" gap.
+# Reads the PR's tier label, walks approving reviewers, and checks each
+# approver's Gitea team membership against the tier's eligible-team set.
+# Marks pass only when at least one non-author approver is in an eligible

-## Known Limitations
-
-### Playwright / browser system libs are not installed
-
-The base `molecule-ai-workspace-runtime` image (`workspace/Dockerfile`) is built on `python:3.11-slim` with Node.js 22, git, and `gh` — about 500 MB. It deliberately **does not** include the system libraries Chromium needs (`libnss3`, `libatk-bridge2.0-0`, `libxkbcommon0`, `libcups2`, `libdrm2`, `libxcomposite1`, `libxdamage1`, `libxrandr2`, `libgbm1`, `libpango-1.0-0`, `libasound2`, etc.). Adding them would inflate the image by ~200–250 MB (~40%) for every workspace, even though only frontend / QA workspaces ever launch a browser.
-
-Practical consequences:
-
- `npx playwright test` (and any other Chromium-driven E2E tooling) **will fail at browser launch** when run from inside an in-container workspace agent.
- The error surface is missing-shared-object messages such as `error while loading shared libraries: libnss3.so` or `Host system is missing dependencies to run browsers`.
- Unit and integration tests (Vitest, Jest, etc.) that don't spawn a real browser are unaffected.
-
-Recommended workflow:
-
-1. **Run E2E in CI**, not in-container. The Gitea Actions self-hosted runner (and the GitHub Actions runner used by mirror repos) has the full Playwright dep set installed and is the supported surface for E2E. Push a branch, let CI run the suite.
-2. **Local debugging** of a single failing spec is best done on a developer laptop with `npx playwright install-deps` run once.
-3. **In-container iteration** on test logic itself is fine — write specs, lint them, type-check them — just don't expect `playwright test` to actually launch a browser.
-
-If a particular workspace role genuinely needs in-container E2E (a dedicated QA template, for instance), the right place to layer Playwright deps is in a **role-specific adapter template image** that does `FROM molecule-ai-workspace-runtime:<tag>` and adds `RUN npx playwright install-deps`. Open a request against `molecule-ai-workspace-runtime` if you need this template stamped.

-# Admin Authentication Runbook
-
-## Test-token route: lock in staging and production
-
-The `GET /admin/workspaces/:id/test-token` endpoint mints fresh workspace auth tokens.
-It is gated by `TestTokensEnabled()` which returns `true` only when `MOLECULE_ENV != "production"`.
-
-**Effect**: if `MOLECULE_ENV` is unset or set to `development` / `dev` in a staging or production
-tenant, the test-token route remains enabled. While the route is protected by `subtle.ConstantTimeCompare`
-against `ADMIN_TOKEN` (returns 404 when disabled, not 403), the safest posture is to lock it
-out in any environment where it is not intentionally used.
-
-### Required: set MOLECULE_ENV in all non-dev environments
-
-```bash
-# In your tenant / EC2 / Railway environment variables:
-MOLECULE_ENV=production
-```
-
-This matches the production tenant default. When `MOLECULE_ENV=production`:
-
- `TestTokensEnabled()` → `false`
- `GET /admin/workspaces/:id/test-token` → 404 (route disabled)
-
-### Startup visibility
-
-workspace-server logs the test-token route state at boot:
-
-```
-Platform starting on ... (dev-mode-fail-open=...)
-```
-
-Additionally, when `TestTokensEnabled()` is `true` (route enabled), the server emits an INFO line
-so operators can confirm the setting in logs:
-
-```
-[molecule-git-token-helper] NOTE: /admin/workspaces/:id/test-token is ENABLED
-(running with MOLECULE_ENV != production)
-```
-
-If you do not see this line and the route is still accessible, verify `MOLECULE_ENV` is not set to
-`development`, `dev`, or any value that is not exactly `production`.
-
-### Dev environments
-
-In local dev (`MOLECULE_ENV=development` or unset with no `ADMIN_TOKEN`), the test-token route
-is intentionally enabled — it is the only way to bootstrap a workspace bearer token without a running
-canvas. This is the correct default for developer workstations.
-
-## Admin bearer token (`ADMIN_TOKEN`)
-
-The platform uses `ADMIN_TOKEN` as the bearer credential for admin-gated endpoints:
-
-| Endpoint | Auth method |
-|----------|-------------|
-| `GET/POST/PATCH/DELETE /workspaces` | `Authorization: Bearer <ADMIN_TOKEN>` |
-| `GET /admin/liveness` | `Authorization: Bearer <ADMIN_TOKEN>` |
-| `POST /org/import` | `Authorization: Bearer <ADMIN_TOKEN>` |
-| `GET /admin/workspaces/:id/test-token` | `Authorization: Bearer <ADMIN_TOKEN>` (enabled only when `MOLECULE_ENV != "production"`) |
-
-Missing or invalid `ADMIN_TOKEN` → AdminAuth fails open in dev mode (no token set), or
-returns 401 in production mode (token set but invalid).
