Update celery exporter

[Panyaze]

mainly version bumps

---

Note

Medium Risk
Python 3.14 and new container latest tagging can break builds or pull semantics; mixin PromQL and dashboard layout changes affect how operators monitor Celery in production.

Overview
Bumps the project runtime from Python 3.13 to 3.14 across CI, .python-version, the main Dockerfile, and Dockerfile.pyinstaller, and tags GHCR images with latest on release builds.

Docs: README adds PyPI install (prometheus-exporter-celery) and a quick /metrics scrape check.

Celery-mixin: Adds a dedicated GitHub Actions workflow (jsonnet generate/fmt, promtool, dashboard-linter, vale, pint) and expands the Makefile with vendored Go tooling and separate prometheus_alerts.yaml / prometheus_rules.yaml generation. Dashboards are refactored around mixin-utils, shared util.libsonnet filters/variables (including optional cluster), dashboardUrls/dashboardIds in config, and richer panels (summary pie charts, success-rate series, task row repeat). Regenerated dashboards_out JSON reflects new PromQL (cluster, multi queue selection, 1w stats, etc.). Alert annotation links use the new URL map.

Mandatory cluster label filter

Medium Severity

Generated Grafana queries now always include cluster="$cluster" in every panel filter, and the hidden cluster variable is populated from label_values(..., cluster). The exporter does not emit a cluster label, and showMultiCluster defaults to false, so typical Prometheus setups that worked with the previous dashboards will match no series and show empty panels.

Wrong label in cluster variable

Low Severity

The cluster template variable query hardcodes the label name cluster in label_values, while panel filters use config.clusterLabel (default cluster). Overriding clusterLabel in config leaves the variable reading one label and queries filtering on another, so variables and panels disagree.
