This commit introduces a new /core:qa command to automate the quality assurance process.
The command can be run with the following options:
- No flags: Runs the full QA suite (linting and tests).
- --quick: Runs only the linters for a fast feedback loop.
- --fix: Runs the full QA suite and iteratively attempts to fix issues using the project's auto-formatter.
The command detects the project type (Go or PHP) and runs the appropriate QA tools.
This addresses the user's request to have an automated and iterative QA command.
