v0.2.16

Features

• Radar ingestion: Added 5-minute Databricks bundle jobs for
  radar_precip (year-round) and radar_hail (Apr–Sep), downloading
  HDF5 files and MERGE-ing into the Delta catalog
  (databricks.yml, scripts/ingest_delta.py)
• Metadata ingestion: *_meta_*.csv files are now ingested as
  Delta tables (scripts/ingest_delta.py)
• CombiPrecip reanalysis: client now compares STAC updated
  against local mtime so CPCH reanalysis overwrites stale CPC files
  (src/foehn/client.py)

Fixes

• Relabeled surface/satellite grids as C3/C4 (previously
  C3/C4/C5), added LST to the C4 description, and stubbed C5 as
  unreleased (src/foehn/collections.py)

Chores

• Pre-commit hook runs ruff check --fix + ruff format
  (.pre-commit-config.yaml)
• Bumped GitHub Actions to Node.js 24
  (.github/workflows/ci.yml,
  .github/workflows/publish.yml)
