Phases 0-1 + Sprint A: module split, CLI layer, org-refresh fix, hygiene

- LICENSE (MIT) + README truth-pass; docs/cli.md CLI contract
- CLI subcommands (src/cli_cmds/) per "TUI for users, CLI for users+AI"
- Hub/detail refactor: keymap dispatch, modal split, action enum, BgMsg bus
- Fix: org repos were never refreshed (owner==username match); refresh now
  parallel — 49 repos in ~11s, surfaced 70 previously invisible PRs
- Fix: 3 date bugs in detail/git.rs (format-local, Local::now, 1y month math)
- Stash indicator + [m] actions, session persistence, gh CLI token fallback
- Legacy UI modules removed; plan/ docs (roadmap, audit, debate, handoff)
