Add --version command and version metadata

[MarkRx]

User description

Implements #1370

Checks version info from pyproject.toml if running locally* before checking for pip metadata.

• Uses tomlib which was added in 3.11. Will return "unknown" if using 3.10. The other option would be to bump the minimum version to 3.11 or else import a 3rd party toml library

• Enhanced logging by including version metadata in the tags for better traceability.
• Updated the project version in pyproject.toml to 0.2.6.

⚡ Recommended focus areas for review Error Handling The error handling for Python versions below 3.11 could be improved. Currently it silently falls back to pip version check without logging any warning about tomllib unavailability. Path Resolution The pyproject.toml path is checked relative to current directory. This might fail if the script is run from a different directory. Consider using absolute path resolution.

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Score
Possible issue	Add error handling for missing or malformed configuration data to prevent runtime crashes Add error handling for the case when pyproject.toml exists but is malformed or missing the version field. Currently, this would raise a KeyError. pr_agent/version.py [11-13] with open("pyproject.toml", "rb") as f: data = tomllib.load(f) - return data["project"]["version"] + try: + return data["project"]["version"] + except KeyError: + get_logger().warning("Version not found in pyproject.toml") + return "unknown" Apply this suggestion Suggestion importance[1-10]: 8 Why: This is a critical error handling improvement that prevents crashes when pyproject.toml exists but has missing or invalid version data, which could affect the application's stability in production.	8
	Add error handling for file system operations to prevent application crashes Handle potential IOError/OSError when trying to read pyproject.toml file to prevent crashes if the file is inaccessible. pr_agent/version.py [9-11] if os.path.exists("pyproject.toml") and sys.version_info >= (3, 11): import tomllib - with open("pyproject.toml", "rb") as f: + try: + with open("pyproject.toml", "rb") as f: Apply this suggestion Suggestion importance[1-10]: 7 Why: Important defensive programming suggestion that handles potential file system errors when reading pyproject.toml, preventing crashes in case of file permission or access issues.	7
