Add --version option to gpt-copy CLI command

[Copilot]

This PR adds support for the --version option to the gpt-copy CLI tool. Previously, running gpt-copy --version would result in an error:

❯ gpt-copy --version
Usage: gpt-copy [OPTIONS] ROOT_PATH
Try 'gpt-copy --help' for help.

Error: No such option: --version

After this change, the command now works as expected:

❯ gpt-copy --version
gpt-copy, version 2.4.0

Implementation Details

The implementation uses Click's built-in @click.version_option() decorator with importlib.metadata to dynamically retrieve the version from the package metadata. This ensures the version displayed is always consistent with what's defined in pyproject.toml without requiring manual synchronization.

Changes made:

• Added importlib.metadata import to src/gpt_copy/gpt_copy.py
• Added @click.version_option(version=importlib.metadata.version("gpt_copy")) decorator to the main CLI command
• Created comprehensive tests in tests/test_version_option.py to verify the functionality

The --version option is now properly displayed in the help output and follows standard CLI conventions by printing the version and exiting with code 0.

Fixes #32.

Warning

Firewall rules blocked me from connecting to one or more addresses

I tried to connect to the following addresses, but was blocked by firewall rules:

• openaipublic.blob.core.windows.net
  • Triggering command: /usr/bin/python /tmp/tmph0kzzq5h.py /tmp/tmpe1effsan --tokens (dns block)
  • Triggering command: /usr/bin/python /tmp/tmpjdzgbc4i.py /tmp/tmpvqwhr3wq --tokens --top-n 2 (dns block)
  • Triggering command: /usr/bin/python /tmp/tmpkon9knoy.py /tmp/tmpwbps19jd --tokens --include *.py (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
