Lark approval instance and task management via CLI commands.

• Provides 11 API methods across two resource types: instances (get, cancel, cc, initiated) and tasks (remind, approve, reject, transfer, query, add_sign, rollback)
• Requires Lark CLI authentication and specific OAuth scopes for read/write operations on approval instances and tasks
• Must inspect API parameter schemas using lark-cli schema before calling methods to ensure correct field formats
• Depends on lark-cli binary and shared Lark authentication configuration documented in ../lark-shared/SKILL.md
