chore(renovate): optimize uv project dependency update strategy (#475)

- Add lockFileMaintenance with automerge for uv.lock
- Set rangeStrategy to replace to avoid duplicate lockfile PRs
- Enable automerge only for dev deps minor/patch and lockfile maintenance
- Protect against 0.x breaking changes by disabling automerge
- Add rebaseWhen: behind-base-branch for cleaner PR history
