Migrate Documentation to Great Docs (GSI-2478)

[Cito]

Replaces the MkDocs setup with Great Docs (Quarto-based) and fills in the previously missing DAO documentation.

Docs migration (GSI-2478)

• Swap mkdocs.yml for great-docs.yml; move narrative docs from docs/*.md to user_guide/*.qmd at the repo root
• Promote the README to the docs landing page and drop the old README generation step
• Auto-generate the API reference from docstrings; update the publish_docs workflow, devcontainer, and locked dependencies accordingly
• Two pre-render hooks work around current Great Docs limitations (0.14.1): fix_source_link_paths.py restores the src/ prefix in "view source" links, and add_member_anchor_ids.py adds the qualified anchors that API cross-links point to. Both carry TODOs to remove once fixed upstream.

New DAO documentation (GSI-2157)

• The DAO Pattern — concept, trade-offs, and its place in the Triple Hexagonal Architecture
• Data Access Objects — the Dao / DaoFactoryProtocol interfaces, CRUD/find semantics, error model, and a worked custom-provider example
• MongoDB DAO — configuration, queries and filters, indexes, and error handling

All code snippets were executed against the library; the MongoDB examples were verified end-to-end against a real MongoDB container.

Docstring & tooling fixes

• Correct outdated find-mapping docstrings (UUIDs/datetimes are matched natively, not as strings) and tidy a few Raises: blocks for Google-style parsing
• Consolidate the cSpell dictionary into .vscode/settings.json and scope the Markdown formatter to [markdown]
