v0.18.2: feat: carl --version + bump carl-core 0.1.1, carl-studio 0.18.2
@wheattoast11 wheattoast11 tagged this 24 Apr 21:42 
Fresh-install smoke test of carl-studio==0.18.1 from PyPI caught two issues:

1. carl-core not on PyPI (404 on pypi.org/pypi/carl-core). The 0.1.0
   publish attempt from 2026-04-19 failed with PyPI's classic
   "Non-user identities cannot create new projects" 400 error — trusted
   publishers cannot create brand-new PyPI projects from CI. Required
   manual "pending publisher" setup on pypi.org, now done. Bumping
   0.1.0 -> 0.1.1 so the new tag triggers the now-registered trusted
   publisher path.

2. `carl --version` returned "No such option: --version". Every CLI
   user types this reflexively after install. Fixed: --version / -V
   now attach to the root callback in wiring.py (where the bare-carl
   routing callback already lives — Typer only supports one
   @app.callback). Prints "carl-studio <semver>" and exits 0.

TDD red->green on --version: tests/test_cli_version_flag.py (3 tests).
Also includes --version short-form (-V) and output-shape lock.

Versions: carl-core 0.1.0 -> 0.1.1, carl-studio 0.18.1 -> 0.18.2.
uv.lock regenerated. Both wheels build locally.

Workflow pipeline after this commit:
  git tag carl-core@0.1.1 v0.18.2 && git push origin carl-core@0.1.1 v0.18.2
  -> publish-subpackage publishes carl-core==0.1.1 to PyPI (pending publisher now accepts)
  -> publish-root     publishes carl-studio==0.18.2 to PyPI
  -> pip install carl-studio==0.18.2 works end-to-end
