Subject: [PATCH] fix: address review findings from CodeRabbit/Codex

Verified each against current code before fixing; verification details are
in the PR description update.

Fixed:
- issue-classify.md: Rule 0 now requires the addon-submitter-ping marker to
  appear in a comment headed "### @github-actions[bot]", not just anywhere
  in a comment or issue body, so it can't be spoofed to suppress triage.
- ai_triage_context.sh: separator-insensitive addon-slug matching (fixes
  "Calibre-web" -> calibre_web, and the earlier ImmichFrame -> immich_frame
  miss) before falling back to substring matching; sparse-checkout failure
  now surfaces "UNRESOLVED" into the bundle instead of silently proceeding
  addon-less; duplicate-issue search excludes the issue being triaged from
  its own candidate list.
- on_issues_ai_triage.yaml: persist-credentials: false on the read-only
  tooling checkout (nothing in that job pushes); both actions pinned to
  commit SHAs (Dependabot already covers github-actions repo-wide, and
  on_issues_ai.yml already sets this precedent for another AI action);
  model-supplied labels are now filtered to drop anything in the ai-*/ai:*
  control namespace before merging with the deterministic ai-triage/
  ai:classified additions, closing a path where a verdict could
  self-trigger tier 2 regardless of its actual classification.
- daily_ai_fix.yaml: both actions pinned to the same commit SHAs;
  workflow_dispatch inputs.issue/inputs.limit moved out of direct
  ${{ }} interpolation in the run: script and into env vars with numeric
  validation (template-injection); Guard forbidden paths' PR listing
  limit raised 50 -> 300 so it can't silently drop ai-fix/ PRs behind
  unrelated open PRs before the branch-name filter applies.

Skipped (reasons in PR description):
- persist-credentials on daily_ai_fix.yaml's checkout: disabling it
  breaks the only auth path git push currently uses, and the same
  AI_PR_TOKEN is already directly readable via GH_TOKEN env by that job's
  unrestricted Bash(git:*)/Bash(gh:*) tools regardless.
- Splitting untrusted AI analysis into a separate job from PR-creation/
  write access: legitimate defense in depth, but a full architecture
  redesign, not a minimal fix.
- Full hard-limit enforcement (config.yaml immutability, diff caps,
  draft-only status) replicated at the workflow level: heavy lift: the
  prompt already covers these as Claude-followed instructions; only the
  protected-paths check is duplicated as deterministic enforcement,
  which is the single highest-severity one to enforce outside the model.
