Wire the send/receive paths and the chat UI on top of the file plane.
(Committed together because the UI renders the state the core wiring
produces.)
Core:
- CoreCommand::SendChatFile {text, attachment, data}: serve the bytes on
the file plane (serve_attachment) then broadcast the descriptor via
send_chat. CoreCommand::FetchAttachment {from, attachment}: detached
fetch -> AttachmentReady/AttachmentFailed.
- On an inbound Chat with an Image attachment, auto-fetch + defensively
re-validate (decodable + within pixel limits) before delivering;
non-images wait for an explicit fetch (the Save/Download chip).
- UiEvent::ChatMessage carries the attachment; new AttachmentReady /
AttachmentFailed events keyed by attachment id.
App:
- 📎 attach button + native picker; reads the file, enforces the size
cap, classifies image vs file, mints a random id, optimistically
echoes the message + caches our own bytes (so we see our own image
inline), and sends SendChatFile.
- Renders inline image thumbnails (handle cached by id to avoid the
per-redraw re-upload flicker), file chips with Save/Download, a
loading placeholder for in-flight images, and an error line on
failure. Image messages with no caption still render.
- SaveAttachment: saves immediately if bytes are in hand, else fetches
then saves when ready (pending_saves) via a native save dialog;
filename defaulted from the sanitized descriptor.
- Session-only: attachment bytes/handles cleared on leave, never
persisted.
Binary + clippy clean, 349 lib tests pass.
