- Remove unused import (shlex) and unused global variable (_WAKEUP_W). - Drop dead local variable and simplify redundant conditional. - Add explicit return 0 to _devin_worker to avoid mixed implicit/explicit returns. - Document best-effort exception handlers that intentionally swallow errors.

The code quality improvements in this PR correctly address the CodeQL findings. The changes remove unused imports and variables, fix the mixed-returns pattern in _devin_worker, simplify a redundant conditional check in Navigator.tsx, and add documentation comments to empty exception handlers. All fixes are appropriate and maintain correct functionality.

- Around line 255-257: Apply one explicit process-cleanup error policy in
gascity/scripts/gc-session-devin: at lines 255-257 catch only the exited-process
case before deleting the worker PID file; at lines 287-289 treat PermissionError
as unknown/error rather than an absent child; at lines 391-393 report
interrupt-delivery failures instead of treating every OSError as success; and at
lines 683-699 preserve child tracking while surfacing unexpected termination,
wait, and unlink failures.
- Around line 35-50: Update the wakeup-descriptor setup around
signal.set_wakeup_fd: close the existing _WAKEUP_R and retire the currently
registered wakeup descriptor before calling os.pipe(). Register the new write
descriptor before assigning _WAKEUP_R, and on any setup failure close both newly
created pipe descriptors while preserving the previous state as appropriate.

…dback - Retire the previous wakeup descriptor before creating a new self-pipe and roll back on setup failure, avoiding fd aliasing. - Distinguish ProcessLookupError from PermissionError/OSError in worker stop, child process checks, interrupt, and local-command cleanup paths. - Preserve the child pid file when the local command cannot be terminated.
