fix(desktop): debounce per-keystroke draft persistence writes

The salvaged draft-persistence effect wrote to localStorage on every
keystroke — the composer's per-keystroke path was deliberately slimmed
down previously, so debounce the write (400ms) and flush pending text on
scope change/unmount so a fast session switch can't drop trailing
keystrokes. Also add AUTHOR_MAP entry for the salvaged commit.
