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. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

-  #
-  # The REAL-boot complement to the deterministic unit suite
-  # (workspace_provision_platform_boot_test.go). Provisions a REAL staging
-  # claude-code workspace on the PLATFORM-managed path — provider=platform,
-  # model=moonshot/kimi-k2.6, NO tenant LLM key — and asserts it reaches
-  # status=online (NOT not_configured) and a completion returns 200, via the same
-  # online-wait + completion-assert the BYOK job uses.
-  #
-  # Why a SEPARATE job (not a matrix leg of e2e-staging-saas): the platform path
-  # injects NO secret and pins a different model, so its env block diverges from
-  # the BYOK job's. A dedicated job keeps each path's "verify key present" preflight
-  # honest (BYOK requires a key; platform requires its ABSENCE not to matter) and
-  # gives the regression its own named commit-status for branch protection.
-  #
-  # Add `E2E Staging Platform Boot` to branch protection after 3 consecutive
-  # green runs on main (de-flake window; this path shares the cp#245
-  # boot-timeout flake surface the BYOK job has, so it must prove stable before

-# 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
-```

-// "canvas-created claude-code workspace boots NOT_CONFIGURED" production
-// incident (RFC#340 Fix A #2187, canvas Fix C #2188).
-//
-// THE BUG (what shipped to prod):
-//   A claude-code workspace created via the canvas with provider=Platform +
-//   model="moonshot/kimi-k2.6" booted NOT_CONFIGURED. Unit tests passed; the
-//   REAL boot path was broken. ensureDefaultConfig generated a config.yaml that
-//   carried NO derived `provider:` key, so the cp#329 config-bundle the adapter
-//   actually reads left molecule-runtime config.py to slash-split the model id
-//   "moonshot/kimi-k2.6" -> provider="moonshot", which is NOT in the providers
-//   registry -> NOT_CONFIGURED.
-//
-// THE FIX A INVARIANT (this file pins it, and pins it for the WHOLE class):
-//   ensureDefaultConfig MUST stamp the manifest-derived provider into the
-//   generated config.yaml — at BOTH the top level and under runtime_config —
-//   for every (runtime, model) the providers SSOT maps to a platform provider.
-//   The single-combo pin (TestEnsureDefaultConfig_StampsDerivedProvider in
-//   workspace_provision_test.go) proves the headline case. THIS file closes the
-//   gap that single pin leaves: it is PARAMETRIZED OVER THE SSOT, so when a NEW
-//   platform model is added to providers.yaml for claude-code (or any runtime
-//   with a platform arm), the new id is automatically covered — a future
-//   platform model that fails to derive `provider: platform` fails THIS test at
-//   build time, before it can ship a NOT_CONFIGURED boot.
-//
-// WHY SSOT-DRIVEN AND NOT A HAND-MAINTAINED LIST:
-//   The original bug was a divergence between "what the canvas offers"
-//   (providers.yaml platform arm) and "what the config generator stamps". A
-//   hardcoded test model list would itself drift from the SSOT and re-open the
-//   same divergence gap. By enumerating the platform model set directly from the
-//   loaded providers.Manifest (the SAME manifest ensureDefaultConfig's
-//   deriveDefaultConfigProvider resolves against), this test cannot fall behind
-//   the offered set: add a platform model, get a test case for free; the test
-//   only passes if the generator actually stamps it.
-//
-// SCOPE: deterministic, no live infra. The REAL-boot complement (provision a
-// staging workspace and assert status=online + a completion returns 200 for the
-// SAME combo) is the bash staging harness — see
-// tests/e2e/test_staging_full_saas.sh (E2E_LLM_PATH=platform) and the
-// e2e-staging-platform-boot job in .gitea/workflows/e2e-staging-saas.yml. That
-// asserts the REAL artifact (booted status / completion); THIS asserts the
-// deterministic config-generation invariant the real boot depends on.
