Replace ProcessExists() checks in witness and refinery managers with
tmux session detection. Agent liveness should be derived from tmux
session state, not PID probing (per ZFC tracking principles).
- Remove util.ProcessExists() from witness/manager.go and refinery/manager.go
- Delete internal/util/process.go and process_test.go (now unused)
- Foreground mode and Stop() now rely solely on tmux HasSession/KillSession
Closes: hq-yxkdr (recentDeaths already removed)
Closes: hq-1sd4o (ProcessExists removed)

Create util.ExecWithOutput and util.ExecRun to consolidate repeated
exec.Command patterns across witness/handlers.go and refinery/manager.go.
Changes:
- Add internal/util/exec.go with ExecWithOutput (returns stdout) and
ExecRun (runs command without output)
- Refactor witness/handlers.go to use utility functions (7 call sites)
- Refactor refinery/manager.go, removing unused gitRun/gitOutput methods
- Add comprehensive tests in exec_test.go

Inverse of 'gt rig shutdown'. Starts rig patrol agents:
- Checks tmux sessions to avoid duplicates
- Starts witness if not running
- Starts refinery if not running
- Reports what was started vs skipped
Also adds ProcessExists util function needed by witness/refinery managers.
Move duplicated processExists function to shared util package:
- Create internal/util/process.go with ProcessExists function
- Add internal/util/process_test.go with basic tests
- Update witness/manager.go to use util.ProcessExists
- Update refinery/manager.go to use util.ProcessExists
- Remove local processExists functions from both files

Prevents data loss from concurrent/interrupted state file writes by using
atomic write pattern (write to .tmp, then rename).
Changes:
- Add internal/util package with AtomicWriteJSON/AtomicWriteFile helpers
- Update witness/manager.go saveState to use atomic writes
- Update refinery/manager.go saveState to use atomic writes
- Update crew/manager.go saveState to use atomic writes
- Update daemon/types.go SaveState to use atomic writes
- Update polecat/namepool.go Save to use atomic writes
- Add comprehensive tests for atomic write utilities
