fix(ci): bypass docker login + macOS Keychain for image publish
Six prior PRs (#273, #319, #322, #341, #484, #486) all kept calling `docker login` and tried to coerce credsStore via increasingly elaborate config tricks. None worked. The latest publish-canvas-image and publish-platform-image runs on main are still failing with: error storing credentials - err: exit status 1, out: `User interaction is not allowed. (-25308)` Verified locally on the runner host (2026-04-16): `docker login` on macOS unconditionally writes credentials to osxkeychain after a successful login, regardless of the config presented to it. # I wrote this: { "auths": {}, "credsStore": "", "credHelpers": {} } # After `docker login --config <dir> ghcr.io ...` succeeded: { "auths": { "ghcr.io": {} }, # empty — auth is in Keychain "credsStore": "osxkeychain" # Docker rewrote it back } So `--config` flag, DOCKER_CONFIG env var, credsStore="" etc. all share the same fate: Docker re-enables osxkeychain after every successful login. The Mac mini runner is a launchd user agent with a locked Keychain, so storage fails with -25308. This PR replaces the `docker login` invocation entirely. We write `base64(user:pat)` directly into the disposable DOCKER_CONFIG's `auths` map. `docker/build-push-action@v5` and the daemon honor the auths map for push without ever calling `docker login`, so the Keychain is never involved. Same shape in both workflows: - publish-canvas-image.yml — single registry (ghcr.io) - publish-platform-image.yml — two registries (ghcr.io + registry.fly.io) Fly username remains literal "x". Security: - Token env vars never echoed. Heredoc writes the auth blob via `umask 077` (file mode 600). The temp config dir lives under RUNNER_TEMP and is reaped at job end. - Diagnostics preserved (docker version + binary ls + registry keys only, no values) so future runner permission regressions remain visible without leaking secrets. Equivalent to closed PR #464 — re-opening because main is still broken (verified by inspecting the most recent failure). The closing comment on #464 stated the issue was already addressed by #341, but it isn't.
