feat: check workspace version on import

[Jammy2211]

Summary

Add a check_version(__version__) call to autogalaxy/__init__.py so workspace/library version mismatches surface on every script run, not just welcome.py. Pairs with the upstream PyAutoConf change (PyAutoLabs/PyAutoConf#100) which extends check_version to read from config/general.yaml and adds a YAML-driven bypass for main-branch users.

API Changes

None to autogalaxy's public API. Importing autogalaxy now triggers a workspace-version check via autoconf.workspace.check_version, which may emit a warning (no version source found) or raise autoconf.workspace.WorkspaceVersionMismatchError (workspace and library versions disagree). Users on main-branch clones who hit this should disable via version.workspace_version_check: False in config/general.yaml — see PyAutoLabs/PyAutoConf#100 for the full rationale.

See full details below.

Test Plan

• pytest test_autogalaxy/ stays green
• python -c "import autogalaxy" from autogalaxy_workspace/ succeeds silently
• python -c "import autogalaxy" from /tmp warns with the new message text

Full API Changes (for automation & release notes)

Changed Behaviour

• import autogalaxy now calls autoconf.workspace.check_version(autogalaxy.__version__) at the end of autogalaxy/__init__.py. May warn (no version.workspace_version in config and no version.txt) or raise autoconf.workspace.WorkspaceVersionMismatchError (versions disagree).

Migration

• Users on main-branch workspace clones should add to config/general.yaml:

  version:
    workspace_version_check: False
