feat(desktop): drag sessions into chat as @session links + spawn loader

Drag a sidebar session into the composer to drop an @session:<profile>/<id>
chip the agent resolves via session_search. New READ shape dumps a whole
session by id (head+tail when large); a `profile` param reads another
profile's DB read-only, and a cross-profile locate scan resolves bare ids
when the model drops the owning profile from the link.

Also: ASCII "waking up <profile>" overlay during lazy gateway swaps,
global haptic rate-limit to kill the reconnect-storm "clickity" buzz, and
reauth toasts surfaced once per disconnect instead of every backoff tick.
