fix(scripts): migrate ghcr.io→ECR + raw.githubusercontent.com→Gitea (#46)

Per documentation-specialist's grep agent (2026-05-07T07:30, see
internal#46): runtime-breaking ghcr.io references in shell scripts +
docker-compose + the slip-past-workflow lint_secret_pattern_drift.py
all need migration. These were missed by security-auditor's
workflow-only audit.

Files (6):

- .github/scripts/lint_secret_pattern_drift.py:40 — workspace-runtime
  pre-commit-checks.sh consumer URL: raw.githubusercontent.com →
  Gitea raw URL (https://git.moleculesai.app/molecule-ai/.../raw/
  branch/main/...). The lint job runs in CI and would 404 today.

- scripts/refresh-workspace-images.sh:54 — workspace-template image
  pull URL: ghcr.io → ECR (153263036946.dkr.ecr.us-east-2.amazonaws.com).

- scripts/rollback-latest.sh — full rewrite of header + auth flow:
  * ghcr.io/molecule-ai/{platform,platform-tenant} → ECR
  * GITHUB_TOKEN with write:packages → AWS ECR auth
    (aws ecr get-login-password). Per saved memory
    reference_post_suspension_pipeline, prod cutover is to ECR.
  * Updated header docs to match new auth flow + prereqs.

- scripts/demo-freeze.sh:13,17 — comment-only ghcr → ECR
  (the script doesn't currently exec these URLs, but the comments
  describe the cascade and need to match reality).

- docker-compose.yml:215-216 — canvas image: ghcr.io → ECR + updated
  the auth comment to describe `aws ecr get-login-password` flow.

- tools/check-template-parity.sh:21 — inline curl install instructions:
  raw.githubusercontent.com → Gitea raw URL.

Hostile self-review:

1. rollback-latest.sh's GITHUB_TOKEN→aws-cli auth swap is a behavior
   change. Operators using this script now need aws CLI
   authenticated for region us-east-2 with ECR pull/push perms.
   Documented in updated header. Operators who don't have aws CLI
   will get 'aws: command not installed' which is a clear failure
   mode (not silent).
2. The Gitea raw URL shape (/raw/branch/main/) differs from GitHub's
   raw.githubusercontent.com structure. Verified pattern by
   inspecting other Gitea raw URLs in the codebase. If Gitea's URL
   changes (1.23+), update via the same one-line edit.
3. Doesn't touch packer/scripts/install-base.sh which has a similar
   ghcr.io ref per the grep agent's findings — that's bigger-scope
   (packer build pipeline) and lives in molecule-controlplane-ish
   territory; filing as parked follow-up under #46 if not already.
