Subject: [PATCH 1/2] fix(@angular/cli): correct boolean parsing in MCP example
 front matter

This commit fixes a bug in the `parseFrontmatter` utility where boolean values (true/false) were being incorrectly parsed as strings.

The Zod schema validator for the `experimental` flag would reject these string values, causing the example database generation to fail.

The parser has been updated to explicitly check for "true" and "false" strings and convert them to their corresponding boolean types, ensuring that the front matter is parsed correctly. This fix is applied to both the build-time database generator and the runtime tool.

Subject: [PATCH 2/2] feat(@angular/cli): promote MCP `find_examples` tool to a
 stable tool

The `find_examples` MCP tool has undergone significant enhancements, including the implementation of a structured relational database, advanced filtering, weighted search ranking, and snippet support.

Given its maturity, robustness, and utility, the tool is now considered stable and is promoted to the default set of enabled tools for the MCP server. It is moved from the experimental list to the stable list.
