fix(cliproxy): remove stable version cap, only v81-88 are faulty

- Set CLIPROXY_MAX_STABLE_VERSION to 9.9.999-0 (effectively no cap)
- v89+ are all stable, no longer show experimental warning
- Only v81-88 remain marked as faulty with known bugs
- Simplified lifecycle.ts to remove redundant experimental warning
