## Summary
- Add `--progress=plain` to all `dagger call` invocations in mise tasks to prevent SIGTTOU hangs
## Root cause
Mise runs task scripts in a child process group that is not the terminal's foreground group. When `dagger call` detects a TTY (inherited from the interactive shell), it tries to render its TUI progress display, which requires terminal ioctls. Since the process is not in the foreground group, the kernel sends SIGTTOU, stopping the process indefinitely.
This only manifests when running from an interactive terminal (e.g. `pre-commit run --all-files` in fish/wezterm). CI and piped contexts are unaffected since there's no TTY.
## Changes
- `mise-tasks/validate-workflows` — add `--progress=plain`
- `mise-tasks/frigate-export-model` — add `--progress=plain`
- `mise-tasks/provision-ringtail` — add `--progress=plain`
## Test plan
- [x] `pre-commit run --all-files` completes without hanging
- [ ] Verify in interactive fish/wezterm terminal

## Summary
- Review runner config against v12.7.0 defaults — added `shutdown_timeout: 3h`, no breaking changes found
- Add `validate_workflows` Dagger function using `forgejo-runner validate --directory .` inside upstream container
- All 6 workflows pass v12.7.0 schema validation
- Wire `mise run validate-workflows` task and pre-commit hook on `.forgejo/workflows/` changes
- Mark both leaf Mikado cards (`review-runner-config-v12`, `validate-workflows-against-v12`) complete
## Mikado State
After merge, `upgrade-k8s-runner` goal card has no unmet dependencies — ready to execute the actual image bump in a follow-up PR.
## Test Plan
- [x] `dagger call validate-workflows --src=.` passes (all 6 workflows OK)
- [x] Pre-commit hooks pass
- [ ] Reviewer: confirm `shutdown_timeout: 3h` addition to ConfigMap looks reasonable
