Support @ignoreDocs JSDoc tag to exclude files from Docs app structure

Some files in the ai/ directory (like ai/mcp/server/github-workflow/services/queries/issueQueries.mjs) are valid modules but are not intended to be displayed in the public Docs app. While we have implemented filtering for ai.examples and empty folders, we need a more declarative way to exclude specific files or classes from the Docs app navigation tree.

Goal

Implement support for a custom JSDoc tag @ignoreDocs. When this tag is present in a file's top-level comment block, jsdocx.mjs should skip generating a structure entry for it.

Implementation Details

1. Update buildScripts/docs/jsdocx.mjs:

   • In the parsing loop, check if the docs object (the JSDoc output for a file) contains the @ignoreDocs tag.
   • If the tag is found, skip adding the item to the neoStructure array (or filtering it out).
   • Ensure this check happens before or during the structure generation phase.

2. Usage:

   • Add * @ignoreDocs to the top-level JSDoc comment of ai/mcp/server/github-workflow/services/queries/issueQueries.mjs and potentially other query modules.

Verification

• Add the tag to issueQueries.mjs.
• Run npm run generate-docs-json.
• Verify issueQueries is no longer in docs/output/structure.json.
