Research MCP server additions

[simongray]

Some inspiration from Opus, where 3 is a synthesis of the former two, but I think all are valid as inspiration:

dannet-mcp-enhancements_1.md
dannet-deep-enhancements_2.md
dannet-mcp-roadmap_3.md

dannet-mcp-roadmap_v4.md

I've implemented some LLM-tailored changes to the docstrings based on this report by Opus, but will need to review and access each single change:

dannet-docstring-analysis.md

I'm also unsure whether it actually got done or not. This will need investigation.

The entity and search endpoints of DanNet now return well-formed JSON-LD, so much of the Python code can be heavily simplified:

dannet-mcp-modernization-plan.md

The MCP server has been rewritten (vibe code style) to take advantage of the JSON-LD refactor of DanNet. The only tool out of 12 that didn't seem to work was the autocomplete one. In general, the MCP server seems to work a lot better now that it gets well-formatted data of a higher semantic quality.

I had Opus create a report of where to take things now which is quite decent:
