re-organize the 'Feature Group' labels

[devoncarew]

We may want to re-organize the 'Feature Group' labels for the MCP tools, from here:

https://github.com/dart-lang/ai/tree/main/pkgs/dart_mcp_server#tools

• we're not consistent w/ multi-word labels (static analysis, static_analysis, runtime analysis)
• I don't know that there's any emerging pattern wrt feature group labels, but from the firebase MCP page, I see all their group labels use single words (https://firebase.google.com/docs/cli/mcp-server#capabilities)
• I myself don't know how relevent the feature group label is to the LLMs consuming the tools

I would likely propose that we standardize on analysis, project, packages, runtime, editor, and configuration.

We may also want to do some cleanup / normalization on the tool names themselves; I don't know what would best help either categorize them, or, make them more consumable to LLMs.

The feature group here isn't actually a part of the MCP server, it only exists in this table afaik.

I would just standardize on a user readable name (so, spaces)

Gotcha; I'll close this in favor of #172 (I think categorization can be wrapped up generating the tool list).
