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.

Implements gt-cik.2: Create crew workspace command with:
- internal/crew/types.go: CrewWorker type definition
- internal/crew/manager.go: Manager for crew lifecycle
- internal/crew/manager_test.go: Unit tests
- internal/cmd/crew.go: CLI command with --rig and --branch flags
Crew workers are user-managed persistent workspaces that:
- Clone repo into <rig>/crew/<name>/
- Create optional feature branch (crew/<name>)
- Set up mail directory for delivery
- Initialize CLAUDE.md with crew worker prompting
- Are NOT registered with witness (user-managed)
