What

This PR updates project documentation, improves developer tooling, and introduces a bug fix for origin and port comparison in REST API permission checks.

Why

The previous REST API permission checks did not adequately handle environments using different ports on the same host (e.g., localhost:8888 vs. localhost:8890), which caused issues in local development environments. Additionally, the developer workflow needed clearer instructions and automated pre-commit checks to improve code quality and onboarding.

How

• REST API Permission Validation:

• Updated is_url_from_host in Abstract_REST_Controller.php to accept an optional port parameter, ensuring both host and port are compared.

• Changed visibility of is_url_from_host from private to protected.

• Updated check_api_permissions to pass the port when calling is_url_from_host to improve security and correctness.

• Developer Documentation:

• Updated AGENTS.md with instructions for local development using wp-env, including parallel environment setup, explicit CLI commands, and documentation for running pre-commit hooks with Lefthook and lint-staged.

• Developer Tooling:

• Enabled the pre-commit hook for lint-staged in .lefthook.yml.

• Updated .lintstagedrc.mjs to wrap filenames in single quotes instead of double quotes for PHP file linting commands to improve compatibility.

Testing Instructions

1. Set up the local development environment using the updated wp-env instructions in AGENTS.md.
2. Perform a REST API request between environments running on the same host but different ports (e.g., localhost:8888 and localhost:8890) to verify that permission checks evaluate correctly.
3. Modify a PHP file and attempt to commit the change to verify that the lint-staged pre-commit hook triggers automatically and lints the file.
