image: retain ordered placements in the grid
...
Replace the per-cell image marker with sparse placement spans attached to
grid lines. A placement owns all of its spans and records the input
protocol, application image and placement IDs, z-index, and creation order.
This retains overlapping image layers without storing a list in every grid
cell. Grid operations move, split, clip, and remove only the affected spans.
Use the input protocol to determine image/text interaction: later text
damages SIXEL spans, while Kitty placements remain and are ordered by their
z-index. Rendering then adapts that one logical scene for each client,
rather than changing its semantics according to whether the outer terminal
uses Kitty or SIXEL.

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.

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.

C=1 is parsed and stored as an image-placement flag, suppressing cursor movement and scrolling as required by the Kitty protocol.
