- src/Chat.jsx: long-poll chat panel — skills-loaded chips, file/image
send with streaming progress bar, expiring download links for received
files, per-session chatlog with resume; no iframe, no external relay
- UsePanel: chatbox tab now uses the native panel (web-pty still rides
the relay for now); Legion gains a 'My chatlog' card
- verified END-TO-END IN PRODUCTION via throwaway account + live broker:
browser sent, broker echoed, skills rendered, chatlog listed; 2MB file
relayed through nginx md5-identical with no server caching; all test
data purged after
