This commit introduces a new `/core:perf` command with subcommands to profile performance for Go and PHP projects.
Implemented subcommands:
- `/core:perf test`: Profiles the test suite for Go and PHP projects, identifying slow tests and providing actionable suggestions.
- `/core:perf request <url>`: Profiles HTTP requests and provides suggestions for optimization.
- `/core:perf query <query>`: Analyzes slow database queries for MySQL, providing suggestions for indexing.
- `/core:perf memory [script_path]`: Analyzes memory usage for Go and PHP projects.
Changes made:
- Created a new `perf` plugin with the necessary directory structure and metadata.
- Registered the plugin in the marketplace.
- Implemented the `/core:perf` command and its subcommands.
- Added scripts for each subcommand with logic for both Go and PHP.
- Improved the scripts based on code review feedback, including:
- Fixing incorrect Xdebug usage in the PHP test profiler.
- Improving the PHP memory profiler with Xdebug.
- Adding dependency checks for `xmlstarlet` and `bc`.
- Improving error handling and dependency messages.
- Adding cleanup for temporary files.
- Documenting the MySQL dependency.
