feat(01-03): integration tests for Slack flow, rate limiting, and agent persona
- tests/unit/test_ratelimit.py: 11 tests for Redis token bucket (CHAN-05)
- allows requests under limit, rejects 31st request
- per-tenant isolation, per-channel isolation
- TTL key expiry and window reset
- tests/integration/test_slack_flow.py: 15 tests for end-to-end Slack flow (CHAN-02)
- normalization: bot token stripped, channel=slack, thread_id set
- @mention: placeholder posted in-thread, Celery dispatched with placeholder_ts
- DM flow: same pipeline triggered for channel_type=im
- bot messages silently ignored (no infinite loop)
- unknown workspace_id silently ignored
- duplicate events (Slack retries) skipped via idempotency
- tests/integration/test_agent_persona.py: 15 tests for persona in prompts (AGNT-01)
- system prompt contains name, role, persona, AI transparency clause
- model_preference forwarded to LLM pool
- full messages array: [system, user] structure verified
- tests/integration/test_ratelimit.py: 4 tests for rate limit integration
- over-limit -> ephemeral rejection posted
- over-limit -> Celery NOT dispatched, placeholder NOT posted
- within-limit -> no rejection
- ephemeral message includes actionable retry hint
All 45 tests pass
