refactor: remove legacy tools format, use permission only

BREAKING: Requires OpenCode 1.1.1+

- Remove supportsNewPermissionSystem/usesLegacyToolsSystem checks
- Simplify permission-compat.ts to permission format only
- Unify explore/librarian deny lists: write, edit, task, sisyphus_task, call_omo_agent
- Add sisyphus_task to oracle deny list
- Update agent-tool-restrictions.ts with correct per-agent restrictions
- Clean config-handler.ts conditional version checks
- Update tests for simplified API
