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
