Answers three gaps: no way to delete a single poker session (only clear_all),
no way to browse past sessions, and Lyra could only see aggregate stats.
- poker.list_sessions() (per-session summary + hand count + recap flag) and
poker.delete_session() (removes a session + its hands/reads/observations/
stacks/rituals; keeps the persistent villain file).
- /history page (date, stakes, venue, net, hours, recap link, per-row delete with
confirm) + /history/data + DELETE /history/{id}. Nav links from chat + HUD.
- recent_sessions read tool, added to the shared lookups so Lyra can answer
"how'd my last few sessions go?" in either mode.
- Delete is UI/CLI only — deliberately not a Lyra tool.
- test_modes.py +2 (list/delete, recent_sessions); 44 green.

"""Web server for the vendored chat UI.

|
|
Serves the static single-page UI and implements the small endpoint contract it
|
|
expects (originally provided by the old Node relay), backed by the new Python
|
|
chat loop and SQLite memory. SQLite is the single source of truth for messages:
|
|
`/v1/chat/completions` persists via `chat.respond`, so the UI's `POST /sessions`
|
|
saves are accepted but treated as no-ops (the row is ensured, messages are not

re-stored).
