chore(dead-code): remove unused QueueDepth function

QueueDepth was added for Phase 2/3 busy-return response visibility but
was never wired to a caller. The inline depth query in EnqueueA2A serves
today's enqueue response, making this function dead code.

-      #
-      # WHY HERE (promote point), not at build time:
-      #   The platform-tenant ECR `:latest` tag was last moved 2026-05-10
-      #   and went 3.5 weeks stale because the build step only pushes
-      #   :staging-<sha> + :staging-latest and never re-points :latest. A
-      #   no-arg POST /cp/admin/tenants/:slug/redeploy (whose default tag
-      #   fell through to "latest") then pulled the 3.5-week-old image and
-      #   REVERTED the tenant (incident: molecule-adk-demo, 2026-06-03).
-      #
-      #   The defense-in-depth half of this fix changes that redeploy
-      #   default to :staging-latest, but :latest itself must also be
-      #   kept meaningful. We make :latest track the PROD-BLESSED build,
-      #   not the raw build: by living at the end of deploy-production —
-      #   after `wait-ci` (green main CI), the canary-first batched fleet
-      #   rollout, AND the /buildinfo SHA verification — :latest only ever
-      #   advances to a SHA that is actually green and confirmed running
-      #   across the live fleet. So `:latest` == "current prod image",
-      #   and any consumer that pulls :latest (legacy callers, manual
-      #   `docker pull`, a redeploy that somehow still resolves "latest")
-      #   gets the blessed image instead of whatever happened to build.
-      #

-# Developer SOP — PR review gate auto-fire and stale-head handling
-
-> Last updated: 2026-06-03 (cp#2159 follow-up)
->
-> Applies to: all core-PR authors and reviewers on `molecule-core` and sibling
-> repos using the `qa-review` + `security-review` branch-protection gates.
-
----
-
-## 1. Gitea PR-head workflow-selection rule
-
-**Rule:** For `pull_request_target` and `pull_request_review` events, Gitea
-loads the workflow definition from the **PR's HEAD branch**, not from the
-base (`main`) branch.
-
-This is different from GitHub Actions, where `pull_request_target` always
-loads workflows from the base branch. Gitea's behaviour means:
-
-- A PR that was opened **before** the `pull_request_review` trigger was added
-to `qa-review.yml` / `security-review.yml` will **NOT** auto-fire on review,
-because its HEAD still contains the old workflow YAML (no trigger).
-
-- A PR that was opened **after** the trigger was added (or that has been
-rebased onto a commit containing the trigger) **WILL** auto-fire, because its
-HEAD contains the new workflow YAML.
-
-### Ops implication
-
-| PR head contains `pull_request_review` trigger? | Behaviour on APPROVED review |
-|---|---|
-| **Yes** (cut from current main, or rebased) | Workflows auto-queue, evaluate, and POST the `(pull_request_target)` context automatically. No slash-command needed. |
-| **No** (stale head, opened before #2157) | Nothing fires. Use `/qa-recheck` + `/security-recheck` slash-commands in a PR comment, OR rebase onto current main. |
-
----
-
-## 2. Standard core-PR flow (post-#2157)
-
-```
-1. Author opens PR from a branch based on current main
-   → qa-review + security-review workflows run on pull_request_target
-   → status contexts post (initial eval, usually red until reviews land)
-
-2. Reviewers submit real APPROVED reviews
-   → If PR head has the trigger: workflows AUTO-FIRE on pull_request_review
-   → Contexts flip green (or stay red if reviewer is not in team)
-
-3. [Optional] If contexts did not flip (stale head, event lost, etc.):
-   → Anyone can comment `/qa-recheck` or `/security-recheck`
-   → sop-checklist.yml refires the evaluator (read-only, idempotent)
-
-4. Both qa-review + security-review contexts are green
-   → Plain Do:merge (no force-merge needed)
-```
-
-### Key point
-
-The `/qa-recheck` and `/security-recheck` commands are a **backstop**, not the
-primary path. PRs cut from current main should auto-fire without manual
-intervention.
-
----
-
-## 3. Diagnosing a stale head
-
-If a PR has real team-member APPROVED reviews but the qa/security contexts
-remain red and no workflow run appears on the PR's "Actions" tab for the
-review event, the PR head is likely stale.
-
-### Quick check
-
-```bash
-# From the PR page, look at the head commit SHA, then:
-curl -sS "https://git.moleculesai.app/api/v1/repos/molecule-ai/molecule-core/contents/.gitea/workflows/qa-review.yml?ref=<HEAD_SHA>" \
-  | jq -r '.content' | base64 -d | grep -c 'pull_request_review'
-# 0  → stale head (no trigger in that version of the workflow)
-# >0 → trigger present; auto-fire SHOULD work (if it didn't, file a tracker)
-```
-
-### Automated diagnostic
-
-The test suite includes `test_gate_stale_head_diagnostic.py`, which reports
-"auto-fire impossible for this PR" when the head lacks the trigger. Run it
-in CI or locally with:
-
-```bash
-PR_NUMBER=123 python -m pytest .gitea/scripts/tests/test_gate_stale_head_diagnostic.py -v
-```
-
----
-
-## 4. Rebasing vs. slash-refire
-
-| Approach | When to use | Trade-off |
-|---|---|---|
-| **Rebase onto current main** | PR is genuinely stale (head lacks trigger OR head is far behind main) | Clean history, gets all recent fixes, but requires force-push and re-approval if the branch was protected |
-| **`/qa-recheck` + `/security-recheck`** | PR head is recent but the review event was missed, or you want to avoid rebase churn | Quick, no force-push, but does NOT fix a missing trigger in the head |
-
-**Do not** use slash-refire as a substitute for rebasing a stale head. If the
-workflow YAML in the PR head does not contain `pull_request_review`, no amount
-of rechecking will make auto-fire work.
-
----
-
-## 5. Live-fire verification
-
-The `test_gate_auto_fire_live.py` regression test exercises the full runtime
-path: it submits an APPROVED review to a test PR and polls for the
-`(pull_request_target)` status contexts. It is skipped when no API token is
-available, and is intended to catch runtime non-fire that static structural
-tests (e.g. `test_gate_review_auto_fire.py`) cannot detect.
-
-Run manually with:
-
-```bash
-export GITEA_HOST=git.moleculesai.app
-export GITEA_TOKEN=<your-token>
-export REPO=molecule-ai/molecule-core
-export LIVEFIRE_PR_NUMBER=<test-pr-number>
-python -m pytest .gitea/scripts/tests/test_gate_auto_fire_live.py -v
-```
