fix(deploy): clean up self-explanatory comments and fix unstable mutation dep

- Remove self-explanatory comments in deploy.tsx, tool-input.tsx, use-child-workflow.ts
- Tighten non-obvious comments in use-change-detection.ts
- Destructure mutate/isPending in WorkflowToolDeployBadge to avoid unstable
  mutation object in useCallback deps (TanStack Query no-unstable-deps pattern)
