51f1c0de51 The two Chawan symptoms now have matching fixes: 
- Layout corruption: C=1 is respected.
  - Lingering remnants: tmux now tracks Kitty’s (image ID, placement ID) identity, replaces moved placements, and honors
    placement-specific d=i,...,p=... deletion.

045a25c89a Support Kitty Unicode placeholder image transmission 
- Parse Kitty graphics commands wrapped in tmux passthrough sequences.
  - Accept unpadded base64 payloads emitted by icat.
  - Handle chunked transfers whose final chunk omits m.
  - Track virtual image placements.
  - Convert Unicode placeholders into shared image cells for Kitty and SIXEL clients.
  - Add regression coverage for wrapped, chunked, unpadded input.

a4b8d1c822 Improve SIXEL colour quantization 
Build an adaptive 256-colour palette with median cut instead of using a fixed colour cube. Apply Floyd-Steinberg error diffusion while mapping pixels to reduce banding and preserve image detail.

7748e525a4 Preserve SIXEL pixel dimensions 
Retain the padded canonical pixel canvas separately from the image content. Scale only the populated portion of partial edge cells so an image keeps its exact raster size on the originating terminal while retaining its cell footprint.
