* fix(mobile): dismiss the keyboard after sending to an agent
Sending a message left the software keyboard up, covering the reply the
user was waiting on. Drop it once the send is accepted, on all three send
paths: the terminal live input, the buffered command input, and the chat
composer.
Gated on the tab being an agent session. A plain shell keeps the keyboard
so back-to-back commands stay typeable, a rejected send keeps it so the
handed-back draft stays editable, and the accessory shortcut row is
untouched because dismissing would pull away the row being tapped.
* fix(mobile): gate keyboard dismissal on accepted sends
* fix(mobile): fence keyboard dismissal completions
* fix(mobile): fence stale send completions
* test(mobile): update terminal guard expectations
* fix(mobile): restore rejected buffered drafts by origin
* fix(mobile): preserve intentional buffered draft clears
* fix(mobile): harden send dismissal authority
* test(mobile): preserve Strict Mode send dismissal
* fix(mobile): preserve drafts across terminal remints
* fix(mobile): preserve draft ownership through terminal races
* fix(mobile): harden draft recovery and send freshness
* fix(mobile): fence route reuse and native draft clears
* fix(mobile): preserve native draft edits before clear
* test(mobile): pin the terminal-list sweep that bounds buffered drafts
`bufferedTerminalDraftState.pruneDrafts(retainedHandles)` is the only bound on
two structures that live as long as the session screen — the buffered-draft
record and the pending-restoration map — and nothing failed when it was deleted
or when it was pointed at the raw `terminal.list` handles instead of the
retained set. Both mutations reddened 0 of 3,949 mobile tests.
Adds the wiring pin (both mutations now redden it) plus two behavioural tests
showing why the argument matters: `terminal.list` omits a chat-covered handle
while the desktop graph reloads, so the raw list drops a draft the user is
still holding while the retained set keeps it.
