…n Transport.deliver

GREEN phase — implements the two Phase 2 hook sites that break A<->B deadlock
loops and enforce the envelope protocol scope-limited for BC.

DefaultRoutingPolicy (clawteam/team/routing_policy.py):
  - decide() prefixed with cycle detection BEFORE existing throttle (D-18);
    reuses the existing recentEvents 50-entry bounded window (specifics
    lesson HKUDS#1, no parallel tracker).
  - _topic_hash(envelope): priority chain dedupe_key -> payload.request_id ->
    sha1(content[:128])[:16] (D-19).
  - _detect_cycle(state, envelope, topic_hash): scans last 20 recentEvents for
    >=3 A->B AND >=3 B->A with matching topic_hash (D-20); returns None when any
    entry carries progressSignal: True (Pitfall HKUDS#3 mitigation).
  - Cycle hit persists topic_hash onto routes[route_key].suppressedTopics, saves
    state BEFORE sync emit (Pitfall HKUDS#7), then emits CycleDetected with pair,
    topic_hash, route_keys, window_size=20.
  - Subsequent hits for same route+topic short-circuit with
    reason='cycle_suppressed_existing' (no re-emit, D-21).
  - _append_event gains topic_hash kwarg; pending/aggregated/cycle_suppressed
    entries now carry topicHash so future decide() calls can correlate.

Transport (clawteam/transport/base.py):
  - _pre_deliver_hooks(data) -> TeamMessage: parses JSON bytes, short-circuits
    when msg has none-of-three envelope fields (Pitfall HKUDS#8 BC pass-through),
    otherwise requires all three via TurnEnvelope.model_validate.
  - Per-agent module-level consecutive-malformed counter (D-09); threshold = 8
    consecutive strikes emits DriftRegression (sync). Any valid envelope resets
    the counter for that agent. MalformedEnvelope emitted on every strike.
  - _reset_drift_counters(): test + SprintConductor-teardown helper (Plan 02-11
    contract).
  - Transport ABC unchanged (public interface preserved).

FileTransport.deliver (clawteam/transport/file.py):
  - Invokes _pre_deliver_hooks at the top; MalformedEnvelopeError re-raised to
    caller so MailboxManager can route to dead-letter / surface to the agent.
  - p2p.py falls back to FileTransport.deliver so its delivery path inherits
    the hook automatically; no direct change needed there for v1.

Tests: 698 passed, 1 skipped (Plan 02-09 gate); ruff clean.
Regression matrix (12 templates) and test_runtime_routing.py both still green.

…ressSignal routing-policy field

- clawteam/harness/forced_progress_gate.py: PhaseGate subclass with 2-turn per-agent
  threshold, strict per-agent attribution (no sprint-wide summation), multi-choice
  question writer (A=keep waiting, B=restart agent, C=abort sprint), ForcedProgressTriggered
  emit, module-level increment_turn_counter + reset_turn_counter_state helpers (Pitfall HKUDS#2
  turn_id dedupe).
- clawteam/harness/theater_detector.py: re-export shim — flips the skipif gate on
  tests/test_cycle_detector.py::test_progress_signal_breaks_cycle_streak_per_pitfall3
  so the previously-skipped Pitfall HKUDS#3 progress-signal test now runs green.
- clawteam/harness/artifacts.py: ArtifactStore.__init__ accepts turn_counter_callback
  kwarg (keyword-only, defaults None — BC preserved); write() invokes callback at end
  of hook chain when metadata carries an agent field (D-14 site HKUDS#2).
- clawteam/transport/base.py: module-level _TURN_COUNTER_CALLBACK slot + set_turn_counter_callback
  setter + get_turn_counter_callback test helper; _pre_deliver_hooks invokes callback
  on successful envelope validation (D-14 site HKUDS#1); _reset_drift_counters also clears
  the callback for clean sprint teardown.
- clawteam/team/routing_policy.py: _append_event gains progress_signal kwarg and writes
  progressSignal key onto every recentEvents entry (Plan 02-08 reserved the field,
  Plan 02-09 populates it — Pitfall HKUDS#3 seam).
