Add composite GitHub Action for Octave installation (#259)

Steven Silvester · web-flow · commit ffb078fedb20 · 2026-03-04T11:24:34.000Z
Extracts platform-specific Octave install logic into a reusable
composite action (action.yml) with an install-type input supporting
ubuntu, macos, windows, and ubuntu-flatpak. Updates test.yml to use
the local action.
