drew e28b41f7ec fix(auto-agents): bump post-push CI verify per-call budget 90s → 180s 
Observed healthy slow-runner days where 90 s was insufficient:
the verifier returned ``pending`` and let bad pushes through to
the next dispatcher cycle. 180 s catches the fast-failing checks
(lint/format/push-validation typically fail in 30-60 s) AND gives
headroom for a backlogged runner where those checks may queue for
a minute or two before they actually run.

- Per-call budget: 90 → 180 s (doubles polls-per-window from 9 to
  18; 10 s poll interval unchanged).
- Worst-case cycle math updated in the cycle-budget block comment:
  5 PRs × 180 s = 15 min (was 7.5 min) of polling per cycle in the
  uncapped case. The per-cycle budget (commit 2c43179e7) still
  caps total polling at IMPLEMENTER_POST_PUSH_CI_CYCLE_BUDGET_S
  (default 300 s), so the practical worst case is unchanged.
- Existing TestPostPushCIVerify docstrings update to reference the
  new number.

Escalation integration tests get an autouse fixture that disables
the verifier flag: ``test_implementer_escalation_integration.py``
scripts many ``outcome=resolved`` + head-advanced scenarios but
doesn't stub ``fetch_ci_status``, so without the disable the
verifier would poll the FakeReviewAPI default for the full 180 s
on a real ``time.sleep``. The verifier itself has dedicated
coverage in ``TestPostPushCIVerify`` / ``TestPostPushCIVerifyCycleBudget``.

uv.lock change for the new ``mcp-servers`` optional dep stays
unstaged — it's missing its matching ``pyproject.toml`` entry.

"""Hermetic-Forgejo tests for ``tools/dispatch_implementer.py``.
Phase 2 + 3 + 5b coverage. The dispatcher's per-work-group fetchers
and prompt assembly are exercised against a stubbed
``_claim_runtime.get`` / ``_claim_runtime.post`` (via the
``FakeReviewAPI`` fixture in ``conftest.py``) so no live Forgejo
HTTP fires.
Test families:
- :class:`TestPrefetchEnvFlag` — flag toggling, legacy-prompt
fallback, prefetch-prompt activation.
- :class:`TestPrFixPrefetch` / :class:`TestRequestChangesPrefetch` /
:class:`TestNewIssuePrefetch` — per-work-group prefetch shape +
prompt section assertions.
- :class:`TestPrefetchFailureModes` — fetch failures land in
``error_kinds`` and flip ``data_complete`` correctly.
- :class:`TestPreclone` — Phase 3 clone-section assembly with /
without the feature flag.
- :class:`TestPostSessionAction` — Phase 5b status-comment posting,
idempotency, and clone cleanup error swallowing.

r"""G11 harvest (2026-05-15) — adaptive tier selection behind
``IMPLEMENTER_ESTIMATOR_ENABLED``.
Post-R3 (2026-05-17) contract: the Python dispatcher resolves
the tier in-process (calling the estimator directly when the
flag is on and no explicit hint exists), stashes the resolved
``task-implementor-tier-<slot>`` agent name on the item
context, and emits ``escalation_tier: \`N\``` in the body so the
worker can cite the tier. The retired ``tier-dispatcher`` no
longer reads any ``escalation_tier_hint`` line.
Contract matrix the dispatcher's resolution must honour:
+-------------+----------------+-------------------+--------------------+
| ESCALATION | ESTIMATOR | start_tier | resolved tier |
+=============+================+===================+====================+
| OFF (def) | OFF (def) | n/a | 0 (default) |
| OFF | ON | n/a | estimator-driven |
| ON | OFF | 0 (no labels) | 0 (default) |
| ON | OFF | N > 0 (labels) | N (label-driven) |
| ON | ON | 0 (no labels) | estimator-driven |
| ON | ON | N > 0 (labels) | N (labels override)|
+-------------+----------------+-------------------+--------------------+
The estimator path is the ONLY one that runs an LLM session
from the dispatcher to resolve the tier; every other path is
deterministic. Cross-cycle resumption labels always override the
estimator on the rare overlap case (estimator ON + prior label).
