test(engine): add E2E mission flow tests — 7 new tests

Comprehensive mission lifecycle tests:

- fire_mission_builds_meta_prompt_with_goal: verifies thread spawned
  with project context and recorded in history
- outcome_processing_extracts_next_focus: "Next focus: X" in FINAL()
  response → mission.current_focus updated
- outcome_processing_detects_goal_achieved: "Goal achieved: yes" →
  mission status transitions to Completed
- mission_evolves_via_direct_outcome_processing: 3-step evolution:
  step 1 sets focus to "db module", step 2 evolves to "tools module",
  step 3 detects goal achieved → mission completes. Tests the full
  learning loop without background task timing dependencies.
- fire_with_trigger_payload: webhook payload stored on mission and
  threads_today counter incremented
- daily_budget_enforced: max_threads_per_day=1 → first fire succeeds,
  second returns None

157 tests passing (151 prior + 6 new mission E2E).
