Fix ~50 errcheck warnings across the codebase:
- Add explicit `_ =` for intentionally ignored error returns (cleanup,
best-effort operations, etc.)
- Use `defer func() { _ = ... }()` pattern for defer statements
- Handle tmux SetEnvironment, KillSession, SendKeysRaw returns
- Handle mail router.Send returns
- Handle os.RemoveAll, os.Rename in cleanup paths
- Handle rand.Read returns for ID generation
- Handle fmt.Fprint* returns when writing to io.Writer
- Fix for-select with single case to use for-range
- Handle cobra MarkFlagRequired returns
All tests pass. Code compiles without errors.

detectSender() only detected polecats, not crew workers. Crew workers
like Emma at /Users/stevey/gt/beads/crew/emma were incorrectly
defaulting to mayor/ instead of getting their proper address.
Added /crew/ directory pattern matching parallel to the existing
/polecats/ detection, extracting rig/crewName address format.
