Squash-merge lib-standardisation: adopt repo standards across packaging,
tooling, docs, and CI.
- standardize pyproject.toml (canonical packaging, lint config, extras, GSDFC pydoclint)
- add py.typed marker, modernize type hints and Google-style docstrings
- nest generated docs under docs/lib and docs/mcp; add hand-written wiki
- adopt standard Type A PyPI CI pipeline (tag==version guard + quality gate)
- promote generated CHANGELOG.md; bump version to 0.0.7
- Rename docforge.loader → docforge.loaders and docforge.model → docforge.models
- Update all imports, type stubs, CLI, tests, and documentation references
- Align MkDocs navigation and docforge.nav.yml with new package structure
- Adjust module docstrings and comments for consistency with pluralized naming
- Add filesystem-based module discovery via `discover_module_paths`
- Decouple documentation coverage from Python import behavior
- Ensure GriffeLoader receives a full module list instead of a single root
- Make MkDocs renderer level-agnostic using global package detection
- Emit `index.md` only for true packages, suppress `<package>.md`
- Mirror full dotted module hierarchy into nested docs directories
- Update CLI, exports, and type stubs to expose discovery helper
- Align tests with filesystem-driven module coverage
This fixes missing docs for submodules and removes invalid package `.md` files.
