feat(agent): redesign project_cli with module/method/input protocol

- Replace command/subcommand/args with module/method/input envelope
- Calendar handler uses discriminated union (mode) for read operations
- Strict Pydantic models with extra='forbid' for all calendar methods
- Worker max_iters=7, router prompt simplified (removed project_cli_defaults)
- Skill index cards + per-action files for progressive disclosure
- Frontend/AG-UI aligned to module/method dispatch
- Protocol docs updated to module/method/input contract

WIP: action cards need envelope fix, 2 tests need update, memory
handler needs Pydantic models.
