Subject: [PATCH] ci(release): push dev-<user-prefix>-latest alias for <user>/*
 branches (#31)

Adds a second tag to dev-channel image builds: when a branch is in the
form <prefix>/<whatever>, the image is also pushed as
ghcr.io/keboola/agnes-the-ai-analyst:dev-<prefix>-latest.

Enables per-developer dev VMs on GRPN (and elsewhere) to auto-deploy
without knowing the specific branch slug. Each VM pins its .env to
AGNES_TAG=dev-<prefix>-latest, and the auto-upgrade cron (5 min tick)
picks up the newly pushed image on the next run.

Common Git Flow prefixes are deliberately skipped so feature/*, fix/*,
hotfix/* etc. don't create noise tags. Matched list:
feature, fix, hotfix, bugfix, docs, chore, test, ci, ops, refactor,
perf, style, build.

Verified locally against several branch names:
  zs/my-feature     -> dev-zs-latest
  vr/foo            -> dev-vr-latest
  pc/bar-baz        -> dev-pc-latest
  feature/xyz       -> (skipped)
  fix/bug           -> (skipped)
  main              -> (no-op, stable channel)
  test-no-slash     -> (no-op, no slash)
