[bug] CI stopped running after the monorepo move relocated .github/workflows/ into bifrost/

[matt-wright86]

Summary

CI ran for 91 builds through May 5 (CI #69), then went dark. The monorepo restructure renamed .github/workflows/ → bifrost/.github/workflows/; GitHub only executes workflows from the repo-root .github/workflows/, so since that move no workflow runs on any push, PR, or tag — including every commit on main since. The CI badge in bifrost/README.md is now stale.

Steps to reproduce

1. Open the Actions tab → the most recent run is "CI #69" on May 5 (merge of Added skill and skill installation guide #18); nothing since.
2. git ls-tree main -- .github/workflows/ → empty (no root workflows directory).
3. git show 19080e6 (the monorepo commit) → rename {.github => bifrost/.github}/workflows/ci.yml (100%).
4. Push to main or open a PR today → no workflow is triggered.

Expected behavior

CI (build + tests + lint) keeps running on push/PR as it did through May 5; the release workflow runs on v* tags.

Actual behavior

No runs since the monorepo restructure relocated the three workflows (ci.yml, build.yml, release.yml) into bifrost/.github/workflows/, a directory GitHub ignores. Their internal paths also still assume the repo root is bifrost/ (go-version-file: "go.work", cache-dependency-path: ui/package-lock.json) — i.e. they were authored when bifrost/ was its own repo.

Additional context

Fix: (a) move the three workflows back to the repo-root .github/workflows/; (b) fix the now-wrong relative paths — go-version-file: bifrost/go.work, cache-dependency-path: bifrost/ui/package-lock.json, and a working-directory: bifrost or root make delegation.
