Release 0.13.0

Added

• Caching/pagination annotations — ModuleAnnotations gains 5 new fields: cacheable, cache_ttl, cache_key_fields, paginated, pagination_style (all optional with defaults, backward compatible)
• pagination_style Literal type — Typed as Literal["cursor", "offset", "page"] instead of free-form str
• sunset_date — New field on ModuleDescriptor for module deprecation lifecycle (ISO 8601 date)
• on_suspend() / on_resume() lifecycle hooks — Duck-typed optional hooks for state preservation during hot-reload; integrated into ReloadModuleModule and registry watchdog
• MCP _meta export — Schema exporter includes cacheable, cacheTtl, cacheKeyFields, paginated, paginationStyle in _meta sub-dict
• Suspend/resume tests — tests/test_suspend_resume.py covering state transfer, backward compatibility, error handling

Changed

• Rebranded — "module development framework" → "module standard" in pyproject.toml, __init__.py, README, and internal docstrings
• Module Protocol — on_suspend/on_resume deliberately kept OUT of Protocol (duck-typed via hasattr/callable)
