Stage 3 (Elixir foundation) of the HRDPS plan. Lands the scaffolding that lets the Rust prop-grid-rs HRDPS branch be wired up cleanly when it ships, without further DB or Elixir-side changes. What ships: - `grid_tasks.source` column (default 'hrrr', backfill is a no-op). Replaces the (run_time, forecast_hour, kind) unique index with a 4-column key (..., source) so HRRR and HRDPS analysis/forecast rows for the same cycle coexist. - `Grid.hrdps_only_points/0` — Canadian cells inside HRDPS bbox (49-60°N, -141 to -52°W) but outside HRRR's CONUS bbox. Disjoint from `conus_points/0` by construction so the two grids never double-write the same (lat, lon). - `Grid.point_source/1` — `:hrrr | :hrdps | :neither` classification for a (lat, lon) pair. Routes per-QSO enrichment to the right NWP source. - `GridTaskEnqueuer.seed_with_analysis/2` and `seed/2` accept a `:source` option; defaults to "hrrr" so existing callers are unchanged. - `HrdpsGridWorker` cycle seeder mirroring PropagationGridWorker's shape but for HRDPS's 4×/day cadence. `:hrdps` queue added to base Oban config. What's deferred: - The Rust `prop-grid-rs` worker doesn't yet branch on `task.source`. Until that ships, `HrdpsGridWorker` stays out of runtime.exs cron — it would just produce rows that the Rust worker mishandles as HRRR. Module doc explicitly notes the dormant state. - Map overlay extension and FreshnessMonitor HRDPS staleness deferred to follow-up sessions once real data flows. Activation path documented in the updated plan file. Coverage cap recorded as Stage 8 decision: 60°N for v1 (SRTM stops there). Arctic CDEM deferred to a follow-up plan.
