chore: rename Claudeman to Codeman

Full product rename across 109 files (~834 occurrences):
- Env vars: CLAUDEMAN_* → CODEMAN_*
- Data dirs: ~/.claudeman/ → ~/.codeman/, ~/claudeman-cases/ → ~/codeman-cases/
- tmux prefix: claudeman- → codeman-
- localStorage: claudeman-* → codeman-*
- Package/CLI: claudeman → codeman
- GitHub repo: Ark0N/Claudeman → Ark0N/Codeman
- systemd service: claudeman-web → codeman-web
- Class: ClaudemanApp → CodemanApp

Migration infrastructure for seamless transition:
- state-store.ts: auto-migrates data directories on startup
- tmux-manager.ts: dual-prefix detection (legacy claudeman- sessions)
- app.js: localStorage key migration (preserves old keys)

 ## Origin
 
-This library was extracted from [Claudeman](https://github.com/Ark0N/Claudeman), a Claude Code session manager that runs 20+ autonomous AI agents over 24-hour sessions. The local echo system was built to make mobile and remote access feel instant, then battle-tested across thousands of hours of real usage. After 3 deep code audits, it was extracted into this standalone library with 78 tests covering every state transition.
