This commit refactors the `find_examples` MCP tool to be version-aware, aligning its behavior with the `get_best_practices` tool. The tool now dynamically resolves the code examples database from the user's installed version of `@angular/core`, ensuring that the provided examples are accurate for their specific project version.

Key changes:
- The input schema is updated to accept a `workspacePath`.
- New logic reads the `angular.examples` metadata from `@angular/core/package.json` to locate the version-specific SQLite database.
- If the version-specific database cannot be resolved, the tool gracefully falls back to the generic database bundled with the CLI.
- The database querying logic has been extracted into a separate helper function for better code organization.

This commit fixes a runtime error in the `find_examples` tool that occurred when filtering examples. The error `no such column: experimental` was caused by an incorrect SQL query that attempted to access a column on the FTS virtual table (`examples_fts`) that only exists on the main content table (`examples`).

The fix refactors the database query to use a `JOIN` between the `examples` and `examples_fts` tables. This allows the `WHERE` clause to correctly filter on the `experimental` column from the main table while still leveraging the full-text search capabilities of the virtual table.
