**Added Dual-Tier Stale Policy:**

- Standard timeline: Issues/PRs still follow 365→30 day cycle
- Accelerated timeline: Issues with needs-information label now get 30→7 day cycle
- Separate jobs handle each policy independently
- Detailed messages explaining why items are marked stale and how to keep them open
- Exempt labels: `no-stale`, `needs-information` (for standard policy)
- Only `no-stale` exempt for PRs (`needs-info` doesn't apply)

* refactor(maint): rename options

* fix(init): option parsing

* refactor(client): #options cannot be undefined
