Add tool for getting code quality findings

[koesie10]

Summary

This adds a new tool to get a single code quality finding by its finding number. It returns the response that the REST API returns.

Why

See internal linked issue. This will allow Copilot to retrieve and fix Code Quality findings

What changed

• Adds a new get_code_quality_finding tool and runs the various scripts to update the docs/retrieve icon
• Adds a new code_quality toolset that contains the tool

MCP impact

• No tool or API changes
• Tool schema or behavior changed
• New tool added: get_code_quality_finding

Prompts tested (tool changes only)

• See internal linked issue for the full evaluation, these include:
• "How should I resolve code quality finding 314 for monalisa/smile?"
• "What is the title of code quality finding 29 in monalisa/smile?"
• "What file is code quality finding 29 about in monalisa/smile?"
• "Tell me about code quality finding 29 in monalisa/smile"
• "How severe is code quality finding 29 in monalisa/smile?"

Security / limits

• No security or limits impact
• Auth / permissions considered: The REST API is accessible using the repo scope.
• Data exposure, filtering, or token/size limits considered

Tool renaming

• I am renaming tools as part of this PR (e.g. a part of a consolidation effort)
  • I have added the new tool aliases in deprecated_tool_aliases.go
• I am not renaming tools as part of this PR

Note: if you're renaming tools, you must add the tool aliases. For more information on how to do so, please refer to the official docs.

Lint & tests

• Linted locally with ./script/lint
• Tested locally with ./script/test

Docs

• Not needed
• Updated (README / docs / examples)

This branch is 2 commits behind main (#2600, #2605), which is why the merge status shows BEHIND.

I rebased the branch onto current main locally. The rebased commit is available on fork branch advancedresearcharray/github-mcp-server@koesie10/get-code-quality-finding (a216cc4).

@koesie10 — to update this PR's branch:

git fetch https://github.com/advancedresearcharray/github-mcp-server.git koesie10/get-code-quality-finding
git push origin FETCH_HEAD:koesie10/get-code-quality-finding --force-with-lease

CI was already green on the original commit; no review comments to address. The implementation looks good — follows the same pattern as get_code_scanning_alert, uses raw REST since the Code Quality API isn't in go-github yet, and includes tests with tool snaps.

[advancedresearcharray]

Opened rebased PR #2616 targeting main directly — ready for maintainer review and merge.

[advancedresearcharray]

Opened #2617 to rebase this branch onto latest main (same approach as #2613 for #2608). Merging #2617 will update this PR's branch.

Pull request overview

Adds first-class support for GitHub “Code Quality” findings to the MCP server by introducing a new read-only tool and grouping it under a dedicated code_quality toolset (including icon + docs/snapshots).

Changes:

• Added get_code_quality_finding tool to fetch a single code quality finding by number via the REST API.
• Introduced the code_quality toolset metadata (with Octicon support) and registered the tool in the server tool inventory.
• Updated tool snapshots and generated documentation (README + docs pages) to include the new tool/toolset.
