The orphan-processes check previously killed any Claude process without
a tmux ancestor, which incorrectly targeted user's personal Claude
sessions running in regular terminals.
Now the check is informational only:
- Changed from FixableCheck to BaseCheck (no auto-fix)
- Returns StatusOK with details listing processes outside tmux
- Message advises user to verify processes are expected
- Removed Fix method and related helpers
The orphan-sessions check remains fixable since it only targets gt-*
sessions that don't match valid Gas Town patterns.
