KoNit-K's two commits stamp an owner on tab-strip `+` drafts at create
time, which clears the banner ON the draft tile. Promoting that draft into
main (⌘W on the workspace tab, or a tab dragged out of main) still raised
"Session controls unavailable": closeSessionTile drops the tile AND evicts
its $sessionStates mirror in one tick, resumeSession then makes the
runtime active before the view republishes, and the composer's control
read lands in that gap — storedSessionIdForRuntimeId had no tile, no
mirror, and so never reached the stored-id hint that was there all along.
Give the translation one more rung: the active runtime maps to the
selected stored id. Only main's own binding qualifies; unrelated runtime
ids stay unknown and keep failing closed.
Live (Electron + mock gateway, bot chat in main, `+` draft, close main's
tab so the draft promotes): main → banner; KoNit-K alone → banner on
promote; with this rung → no banner at any step, send works.
Invariant test red on main, green here.
