chore: Bump version to 0.4.0

Key fix: Orphan cleanup now skips Claude processes in valid Gas Town
tmux sessions (gt-*/hq-*), preventing false kills of witnesses,
refineries, and deacon during startup.

Updated all component versions:
- gt CLI: 0.3.1 → 0.4.0
- npm package: 0.3.0 → 0.4.0

+- **Orphan cleanup skips valid tmux sessions** - `gt orphans kill` and automatic orphan cleanup now check for Claude processes belonging to valid Gas Town tmux sessions (gt-*/hq-*) before killing.
