Bolt Console: desktop app with chat list / new chat, dictation, file tools

Add a chat list and server-minted new chats on top of the desk API's
GET/POST /desk/chats:

- server_client.list_chats() / create_chat(), same shape and error
  handling as list_outbox_files().
- Switching is config.set_session(id): a plain reassignment of the
  SESSION_ID every call reads, persisted to session.json. The window
  refuses to switch mid-turn rather than locking.
- gui/chat_list_window.py: a Chats dialog (Ctrl+K) with a QListWidget,
  populated on open, with Refresh and New Chat. Network calls run as
  QRunnables on the global QThreadPool and come back through Signals,
  never from a slot. The header New chat (Ctrl+N) uses the same path.
- Switching clears the local transcript; there is no endpoint for a
  past chat's messages. Bolt's memory is per user, so it carries over.
- Terminal: /chats, /chat <n|id>, and /new (server-minted id, local
  fallback).

This commit also carries the uncommitted work since 54030a7 that turned
this Bolt-Pet fork into Bolt Console: the pet, wake word, TTS and screen
features removed; a Claude Code-style terminal client; the PySide6
window with tool cards, approvals and diffs; mic dictation through the
server's /desk/stt relay; filectl/JSON repairs; and detection of
invented tool results.

Build output (build/, dist/, Release/, *.spec) is now ignored.
