Fix testium --version reporting "unknown" when installed from a wheel

get_testium_version() used pkg_resources (deprecated, slow to import)
and a narrow catch on git.InvalidGitRepositoryError; any other git
exception fell through to the outer except and returned "unknown".

- Use importlib.metadata.version("testium") to read the wheel
  version that setuptools bakes from src/VERSION at build time. Works
  out of any source checkout — pip-installed copies report
  "<x.y> (wheel release)" instead of "unknown".
- Source-checkout path: tried first when prefs.git_supported, broadly
  catches Exception so a missing repo / detached worktree / etc. no
  longer hides the wheel-metadata fallback.
- PyInstaller path: graceful "unknown (binary release)" if the bundled
  VERSION file is unreadable, instead of an unhandled exception.
