claude-ceo-assistant aa22183e52 chore(ci): pin artifact actions to @v3 for Gitea act_runner compatibility (internal#46)
Mechanical pin: 4 `actions/upload-artifact@v4.6.2/v7.0.1` uses → `@v3`. v4+/v7+
rely on a runtime API shape that Gitea's act_runner v0.6.x doesn't fully
support. v3 uses the legacy server protocol act_runner ships end-to-end.

Files (4 uses):
  - .github/workflows/ci.yml:238 (v4.6.2 → v3)
  - .github/workflows/codeql.yml:124 (v7.0.1 → v3)
  - .github/workflows/e2e-staging-canvas.yml:142 (v7.0.1 → v3)
  - .github/workflows/e2e-staging-canvas.yml:150 (v7.0.1 → v3)

YAML parse green on all 3 files.

Sister PRs land for `molecule-controlplane` and `codex-channel-molecule`.
Per internal#46 Phase 2 audit; tracked under that umbrella.

## Canvas build passed ✅ — deploy required
The `publish-canvas-image` workflow is now building a fresh Docker image
(`ghcr.io/molecule-ai/canvas:latest`) in the background.
Once it completes (~35 min), apply on the host machine with:
```bash
cd <runner-workspace>
git pull origin main
docker compose pull canvas && docker compose up -d canvas
```
If you need to rebuild from local source instead (e.g. testing unreleased
changes or a new `NEXT_PUBLIC_*` URL), use:
```bash
docker compose build canvas && docker compose up -d canvas
```
