Subject: ci: add workflow to keep version tags pointing at branch heads
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Maps branches to floating version tags so RTD can build canonical
versioned URLs from a single ref name regardless of branch renames:

- current  -> rolling
- circinus -> 1.5
- sagitta  -> 1.4

The workflow force-moves the matching tag to the pushed SHA on every
push to one of the three branches. Initial seed tags were created
manually; subsequent updates are automatic.
