ci: add arm64-lane pilot (additive shellcheck on Mac runner)

Mac-CI dual-track #233 pilot. Adds a single additive non-required workflow that targets [self-hosted, arm64] runners and runs shellcheck against .gitea/scripts/*.sh. Until a Mac arm64 runner is registered with the `arm64` label, this workflow sits PENDING, which is fine — `arm64` is NOT in branch_protections/main.status_check_contexts (only 'CI / all-required (pull_request)' is required, verified live via API). Why shellcheck for the pilot: pure userspace, no docker.sock, no privileged ops, identical output across arm64/amd64, narrow blast radius. A clean signal for whether the lane works. Pairs with internal#543 (RFC: Mac arm64 native multi-arch runner-base). 88 LoC, well under the <=100 line guidance. No required gate changes.

-# Runs the canary smoke suite against the staging canary tenant fleet
-# after a new :staging-<sha> image lands in ECR. On green, calls the
-# CP redeploy-fleet endpoint to promote :staging-<sha> → :latest so
-# the prod tenant fleet's 5-minute auto-updater picks up the verified
-# digest. On red, :latest stays on the prior known-good digest and
-# prod is untouched.
-#
-# Registry note (2026-05-10): This workflow previously used GHCR
-# (ghcr.io/molecule-ai/platform-tenant) — that registry was retired
-# during the 2026-05-06 Gitea suspension migration when publish-
-# workspace-server-image.yml switched to the operator's ECR org
-# (153263036946.dkr.ecr.us-east-2.amazonaws.com/molecule-ai/
-# platform-tenant). The GHCR → ECR migration was never applied to
-# this file, so canary-verify was silently smoke-testing the stale
-# GHCR image while the actual staging/prod tenants ran the ECR image.
-# Result: smoke tests could not catch a broken ECR build. Fix:
-#   - Wait step: reads SHA from running canary /health (tenant-
-#     agnostic, works regardless of registry).
-#   - Promote step: calls CP redeploy-fleet endpoint with target_tag=
-#     staging-<sha>, same mechanism as redeploy-tenants-on-main.yml.
-#     No longer attempts GHCR crane ops.
-#
-# Dependencies:
-#   - publish-workspace-server-image.yml publishes :staging-<sha>
-#     to ECR on staging and main merges.
-#   - Canary tenants are configured to pull :staging-<sha> from ECR
-#     (TENANT_IMAGE env set to the ECR :staging-<sha> tag).
-#   - Repo secrets CANARY_TENANT_URLS / CANARY_ADMIN_TOKENS /

-name: redeploy-tenants-on-main

-# Auto-refresh prod tenant EC2s after every main merge.
-#
-# Why this workflow exists: publish-workspace-server-image builds and
-# pushes a new platform-tenant :<sha> to ECR on every merge to main,
-# but running tenants pulled their image once at boot and never re-pull.
-# Users see stale code indefinitely.
-#
-# This workflow closes the gap by calling the control-plane admin
-# endpoint that performs a canary-first, batched, health-gated rolling
-# redeploy across every live tenant. Implemented in molecule-ai/
-# molecule-controlplane as POST /cp/admin/tenants/redeploy-fleet
-# (feat/tenant-auto-redeploy, landing alongside this workflow).
-#
-# Registry: ECR (153263036946.dkr.ecr.us-east-2.amazonaws.com/
-# molecule-ai/platform-tenant). GHCR was retired 2026-05-07 during the
-# Gitea suspension migration. The canary-verify.yml promote step now
-# uses the same redeploy-fleet endpoint (fixes the silent-GHCR gap).
-#
-# Runtime ordering:
-#   1. publish-workspace-server-image completes → new :staging-<sha> in ECR.
-#   2. This workflow fires via workflow_run, calls redeploy-fleet with
-#      target_tag=staging-<sha>. No CDN propagation wait needed —
-#      ECR image manifest is consistent immediately after push.
-#   3. Calls redeploy-fleet with canary_slug (if set) and a soak
-#      period. Canary proves the image boots; batches follow.
-#   4. Any failure aborts the rollout and leaves older tenants on the
-#      prior image — safer default than half-and-half state.
-#
-# Rollback path: re-run this workflow with a specific SHA pinned via
-# the workflow_dispatch input. That calls redeploy-fleet with
-# target_tag=<sha>, re-pulling the older image on every tenant.

-# Auto-refresh staging tenant EC2s after every staging-branch merge.
-#
-# Mirror of redeploy-tenants-on-main.yml, with the staging-CP host and
-# the :staging-latest tag. Sister workflow exists for prod (rolls
-# :latest after canary-verify). Both share the same shape — just
-# different CP_URL + target_tag + admin token secret.
-#
-# Why this workflow exists: publish-workspace-server-image now builds
-# on every staging-branch push (PR #2335), pushing
-# platform-tenant:staging-latest to GHCR. Existing tenants pulled
-# their image once at boot and never re-pull, so the new image just
-# sits unused until the tenant is reprovisioned.
-#
-# This workflow closes the gap by calling staging-CP's
-# /cp/admin/tenants/redeploy-fleet, which performs a canary-first,
-# batched, health-gated SSM redeploy across every live staging tenant.
-# Same endpoint shape as prod CP — only the host differs.
-#
-# Runtime ordering:
-#   1. publish-workspace-server-image completes on staging branch →
-#      new :staging-latest in GHCR.
-#   2. This workflow fires via workflow_run, waits 30s for GHCR's CDN
-#      to propagate the new tag.
-#   3. Calls redeploy-fleet with no canary (staging IS canary; we don't
-#      need a sub-canary inside it). Soak still applies to the first
-#      tenant in case of bad-deploy detection.
-#   4. Any failure aborts the rollout and leaves older tenants on the
-#      prior image — safer default than half-and-half state.
-#
-# Rollback path: re-run with workflow_dispatch + target_tag=staging-<sha>
-# of a known-good build.

+//
+// Scope is deliberately narrow: only ctx errors propagate. Other DB
+// errors retain the long-standing documented "fall back to push (today's

+// workspace UUID — NOT the friendly name the operator sees. The friendly

+// canvas Details tab) write it to the trusted workspaces.name DB column.
+// But /registry/register stores the runtime-supplied card verbatim
+// (registry.go: `agent_card = EXCLUDED.agent_card`), so the stored card
+// served at /.well-known/agent-card.json and returned to peers via
+// agent_card_url ends up with name = UUID, description = "", role = null.

+// Fix shape (deliberately minimal, no contract weakening): when the
+// runtime-supplied card's `name` is empty or equals the workspace UUID
+// (the placeholder the runtime had no better value for), the PLATFORM —
+// not the agent — substitutes the friendly value from the trusted
+// workspaces row. Identity stays platform-controlled: the agent never
