Phase C of the two-level undo card: the committer stages around the
whole open card folder — comments included — so gestures in an open
window never land in interim commits; window close flushes the session
as one semantically-named commit ("Edit card 'X'" with the thread as
body bullets, "Mixed update — N changes to card 'X'" when events mix),
with the two-commit foreign/user split preserved and the
comments/.trash purge riding the same bracket. Comment gestures lose
their per-gesture commits structurally (they write inside the held
folder). Branch-switch settle releases every window's staging before
checkout and re-arms on resume.
Fixes two latent pro-m1 defects: the committer was composed without
the store's EchoLedger, so every production commit classified foreign
and was authored Lanework External; and interim flushes dropped
harvest receipts they had not spent, unvouching the session's own
writes at close. Also lands 06's mixed-subject re-ruling (the retired
"Update board" fallback) and phase B's two files missed by the
previous commit's pathspec.
