Add character creation, session management, and DM improvements
- Character creation flow: when no character exists, the CLI launches
into an AI-guided character creation conversation that walks the
player through building their character
- Session saving on quit: added end_session tool that the DM calls
when the player wants to stop playing. Saves current situation and
open threads. CLI also catches Ctrl+C/Ctrl+D and asks DM to save.
- Session recap on start: CLI sends [Session starting] signal, DM
responds with a brief "previously on..." to re-orient the player
- Reset command: `storied reset` clears player/world state for fresh
starts
- DM prompt refinements:
- Narrative rhythm guidance (slower/epic vs faster/beat-by-beat)
- Balance "yes, and..." with world constraints
- Ending sessions gracefully
- UI polish: dim blue rule lines above prompt and before DM response
