feat(hrdps): /weather merges HRRR with HRDPS for north-of-CONUS cells
The /weather map now shows HRRR-derived data wherever HRRR has
coverage and falls back to HRDPS-derived data for Canadian cells
outside HRRR's bbox. North of the 49°N HRRR-coverage line the map
stays populated instead of going blank.

Rust:

- weather_scalar_file::dir_for_hrdps + write_atomic_hrdps land HRDPS
  scalar chunks at `<vt>.hrdps/` so HRRR's `<vt>/` write isn't
  clobbered. The HRRR writer wipes its dir before each write — both
  sources need their own dir to coexist.
- pipeline::run_chain_step_hrdps now derives a ScalarRow for each
  scored cell (same derive_row that HRRR uses; same wire format) and
  writes them via write_atomic_hrdps alongside the .hrdps.prop score
  files.

Elixir:

- ScalarFile.dir_for_hrdps + read_bounds + read_point + exists? all
  walk both `<vt>/` (HRRR) and `<vt>.hrdps/` (HRDPS). read_bounds
  concatenates with HRRR-precedence on overlap (defensive — Rust
  pipeline doesn't write HRRR-overlap cells, but cheap to enforce).
- Weather.weather_grid_at unchanged: it routes through ScalarFile,
  which now transparently returns the union. GridCache stays
  per-valid_time so a single cache entry holds both regions.

Tests cover four scenarios: HRRR-only, HRDPS-only, both-present
union, and HRRR-precedence on the same cell.
