refactor(@angular/cli): remove find_examples tool and associated database rule

Remove the `find_examples` tool from the Angular CLI MCP server, along with the `ng_examples_db`
Bazel rule and associated example files. With the availability of the official Angular developer
skills repository (https://github.com/angular/skills), this local database lookup tool is redundant.
Reduce maintenance overhead and simplify the codebase by eliminating the need to maintain a local
SQLite database of examples within the CLI repository.
