fix: Address workflow template issues from code review

- Fix resolvePartialID stub to use utils.ResolvePartialID (bd-746)
- Add validation for empty wf.Tasks before accessing wf.Tasks[0] (bd-muw)
- Remove || echo fallback from update-hooks verification (bd-0w5)
- Implement ExpectExit/ExpectStdout verification fields (bd-dwh)
- Add warning when depends_on references unknown task ID (bd-aay)
- Add bd update --parent flag to change issue parent (bd-jvu)
