Initial commit: hqt — HQ Terminal TUI

TUI for orchestrating AI coding harness sessions (Claude Code, Codex,
Kiro, etc.) via tmux. Click CLI bootstraps a Textual TUI over
ProjectService/SessionService backed by SQLite, spawning harness
sessions as tmux windows through TmuxManager.

Includes recent fixes:
- Visible Tab focus highlight on dialog OK/Cancel buttons
- Auto-select first project on launch
- Auto-select first session + per-project session-selection memory
- tmux new-window targets an explicit free index, fixing
  "index N in use" failures (broken spawn/attach in attached sessions)
