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• Correct outdated find-mapping docstrings (UUIDs/datetimes are matched natively, not as strings) and tidy a few Raises: blocks for Google-style parsing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]

Looks much nicer than mkdocs.
However, when I clicked User Guide at the top of the page it took me to the old MkDocs site. Is that just me or does that need to be fixed?

The DAO sections were nice - I think they convey the info intuitively and cover everything with appropriate volume.

It's not yet deployed to GitHub pages, that happens only when we merge to main.

But you can great-docs build and great-docs preview locally.

That's how I was testing it out
