Simplify runner image (Dagger Phase 3) (#162)
## Summary

With Phases 1 and 2 complete, the runner image no longer needs most of its bundled tools. This PR strips it down and adds what was missing.

**Removed** (now inside Dagger containers):
- Node.js 24.x
- Docker CLI + buildx plugin
- skopeo
- gnupg, lsb-release, xz-utils

**Added:**
- `tzdata` — fixes the TZ env var (#159, #160, #161) so `TZ=America/Los_Angeles` actually works
- `flyctl` — was being installed from scratch every release

**Workflow changes:**
- Remove "Ensure Dagger CLI" bootstrap steps from both workflows (Dagger is in the image)
- Remove "Install flyctl" step from build-blumeops (flyctl is in the image)
- Remove job-level `TZ` from build-blumeops (moved to runner configmap `runner.envs`)
- Set `TZ: America/Los_Angeles` in runner configmap so all job containers inherit it

## Deployment

After merge:
1. Build and release the new runner image: `mise run container-release forgejo-runner v2.0.0`
2. Sync the runner: `argocd app sync forgejo-runner`
3. Verify: `kubectl -n forgejo-runner exec deploy/forgejo-runner -c runner -- date` (but the real test is running a docs release and checking the changelog date)

# Generic container build workflow
# Triggers on tags matching: <container>-v<version>
# Builds from containers/<container>/Dockerfile if it exists
#
# Uses Dagger to build and push images to the Zot registry.

# Examples:
# nettest-v1.0.0 -> builds containers/nettest/
# devpi-v2.1.0 -> builds containers/devpi/
# foo-v1.0.0 -> skips if containers/foo/ doesn't exist
