v0.2.29

Summary

• 10-beat live smoke passed on session mn_1d2a37a6 (script+prose full pipeline).
• Beat errors propagate to UI/CLI instead of silent None.
• HUD built after successful beat_turn_finish; VIT01 honours update_lines with auto satiety downgrade.
• beat_turn_finish warm uses NOVEL_WARM_DEPTH so slot-6 library options validate correctly.
• Opening beat: mobile sends { start: true }; continue reserved for prose-stage resume.

Test plan

• pytest novel suite (59 tests)
• python scripts/run_beats_smoke.py 10 shenjia_caifa — 0 failures
