Skyler Lehmkuhl 1bfd09f151 Phase 3a-3: low-res image proxy for cold-scrub raster frames 
Scrubbing onto a paged-out raster keyframe flashed blank for the 1-2 frames its
full pixels took to page in. Now a low-res proxy is shown in that gap.

- core: `MediaKind::RasterProxy` (id derived from the keyframe id via
  `raster_proxy_media_id`); `brush_engine::encode_raster_proxy_png` downscales a full
  RGBA buffer to a ≤192px-long-edge PNG. Save writes a proxy beside each resident
  frame's full PNG (paged-out frames keep their existing proxy row, like the full).
  Load eagerly decodes proxies (small) into `RasterKeyframe::proxy`.
- editor: a separate `proxy_layer_cache` in the GPU brush (own recency LRU, budget 64
  since each is ~1/100th a full frame) + `ensure_proxy_texture`/`get_proxy_texture`.
  The raster render, when the full texture isn't resident, blits the proxy mapped to
  the keyframe's FULL logical dims so it upscales via the sampler. F3 VRAM figure now
  includes proxy textures.

When the full pixels land (async fault-in), the full path takes over automatically.
Proxies only exist after a save+reload; freshly-painted unsaved frames stay resident
so they need none.
