The standalone `ccx images` picker had zero Kitty integration, so the
inline image never rendered outside the conversation split. In addition,
two bugs made Kitty rendering unreliable even where it did fire:
- Every render invoked ExtractImageToTemp, which wrote a fresh temp file
per call. Hundreds of stale jpegs piled up and Kitty never got a
stable file path to load. Fixed by persisting the decoded image into
the shared ~/.claude/image-cache/<sessionID>/<pasteID>.png so the
path is stable across renders, re-encoding non-PNG sources (JPEG/GIF)
into PNG to match Kitty's f=100 protocol.
- tmux `allow-passthrough on` drops DCS passthrough from a hidden pane,
so a clear sequence emitted after a window switch never reaches the
terminal and the image lingers over the next window. Promote the
option to `all` during kitty.Supported() so invisible-pane clears get
through, then poll tmux #{window_active} on a 250ms tick (both in the
main TUI and the standalone picker) to detect window switches — tmux
does not forward focus events for intra-session window changes, so
BlurMsg alone is not enough. The poll writes the clear sequence to
os.Stdout the instant we transition to invisible.
Also: picker now handles tea.WindowSizeMsg with InvalidatePaneOffset(),
and the conv view kittyImageLayer path was simplified to share a single
kittyImagePath resolver that always goes through the persistent cache.
Tests added:
- internal/cli/picker_kitty_test.go: image-only kind, blur clear, happy
draw, missing-file clear.
- internal/session/image_cache_test.go: JPEG source re-encodes as PNG
and returns a stable cache path across calls.
