perf(weather): binary cell-pack + canvas overlay + lazy layer prefetch 
Three changes that shrink first-paint and make layer toggles instant:

1. Server: /weather/cells now supports ?format=bin and ?layers=a,b,c. The
   binary "WCEL" pack is ~3× smaller than JSON (Float32 columns, no key
   overhead) and parses with DataView + typed-array views — essentially
   memcpy on the client.

2. Client: replaced JSON parse + per-cell SVG <rect> with a custom
   Leaflet canvas layer. The pack is columnar (lats/lons + Float32Array
   per layer) and each draw is one fillRect per cell against a
   precomputed 256-step color LUT. At low zoom (CONUS, ~80k cells) SVG
   paint cost dominated; canvas keeps it under one frame.

3. Lazy prefetch: the initial fetch only requests the *current* layer
   (~1/19 the bytes). Right after paint, a single background fetch
   pulls every other layer into the same pack. Layer switches that land
   after the prefetch finishes are pure recolor — no network, no
   server CPU.

The /weather/tiles endpoint stays for backward compat. The JSON path of
/weather/cells stays too — the binary path is opt-in via ?format=bin.
