Handle editing focus entirely within TaskParticleView instead of threading
editing state up to StreamView and special-casing the navigation hook.
While editing, the card now registers a capture-phase key listener — the
same pattern the app's other focus overlays use — that consumes Escape
(blurring the field, which flushes the draft and resumes playback) and
swallows stream-navigation keys so they can't pull focus to another
particle. An "Esc to finish" hint shows while editing.
This restores use-stream-navigation-keys to its original form and reduces
the StreamView change to a single `immersive` prop.
