Subject: [PATCH 01/28] fix(native-chat): an open chat moves to the account you
 switch to before its next message

A running chat's agent read its account only when it started, and nothing compared it with the
account a start would use now, so open chats kept answering on the old account after a switch.

The agent a chat runs now records the account its launch used, and the host's replace-before-the-
next-send check replaces an idle one whose account is no longer what a start would use. A chat
mid-reply finishes on the old account first. Claude chats follow; agents whose chats keep the
account they were created on are never compared.

A chat's model-list reads and saves now use the account it runs on, so a moved chat no longer
writes its new account's list under its first account (STA-11281).

Tracked in STA-11211.

Subject: [PATCH 21/28] Offer Hand Off to Another Agent in a chat tab's
 right-click menu

A chat tab outside a terminal pane had no way to continue its conversation
with another agent from the menu; only chats hosted in a terminal pane did.
The usage-limit row's hand-off moves into a shared hook so the menu and the
row open the same dialog with the same saved-transcript context.

Subject: [PATCH 28/28] test: move notice perf contract to the shared hand-off
 hook

The usage-limit notice no longer reads chat tabs itself; useNativeChatHandOff
does and passes its state in. Render the notice through the hook so the
scaling test keeps asserting one tab index per write, zero work on unrelated
writes, and the renamed tab's host feed.
