* feat(terminal): the window's store shows main's pane start status (layout-owner build)
A status-only frame changes one store entry and no pane tree, so the pane's view stays mounted.
* refactor(terminal): keep the frame sync within its line budget
* feat(terminal): every pane main starts shows 'starting' from before it is written (layout-owner build)
* feat(terminal): a pane main is starting waits and attaches; a failed start shows why (layout-owner build)
Fixes owner-visible row 15: a failed agent or setup start no longer opens a plain shell.
* test(terminal): iterate store listeners directly
* fix(terminal): an exit that reports no code keeps its pane, as lost contact (layout-owner build)
* test(terminal): a pane main started attaches to main's terminal at its own grid
* test(terminal): detach census tests assert main's move and frame with the switch on
* test(terminal): exited-pane tests assert main's close with the switch on
These 8 have failed switch-on since #31130 moved the exit close to main.
* feat(terminal): main writes and starts every split of a pane it holds; the window attaches (layout-owner build)
The window's split, a startup split with its command, and a CLI split all go through main's
terminal.split; main's frame mounts the pane, with or without a window intent. Deletes the
window's split wait and withdraw, the split appear intents, and the queued-split skip and cancel.
The e2e helper uses the real split. A startup split leaves focus on its source pane.
* fix(terminal): the attach-only wait leaves sleeping, resuming and held panes to their restore path
* fix(terminal): a split pane attaches to the terminal main bound it to; a taken pane id is refused
Also restores the proof that a split closed while it starts gets one answer and leaves no
pane or start status behind.
* fix(terminal): a window split main cannot start still shows its pane, failed, with why
* fix(terminal): check a taken pane id first, keep the start's own error, clear a gone pane's status
Three test stores gain the pane-start field the window's store always has.
* test(terminal): the admission stub answers whether its pane is still written; a closed pane's failed start clears
* refactor(terminal): the rebound workspaces' bindings show through one call in the bindings module
* test(terminal): a pane main wrote and the user closed mid-start drops its failed status
* fix(terminal): a split main starts is listed to phones and session.tabs without a window's report
* fix(terminal): a reconnect shows its pane starting and why it failed; a lost owner race shows no failure; a split no one asked to see keeps the phones' tab
* fix(terminal): a kept create another owner won shows no failure; the window attaches to the winner
* fix(layout): a pane main closed stays closed when its terminal starts late (dark, layout-owner build only)
* fix(layout): main takes back a CLI split pane whose terminal does not start within 10 s (dark, layout-owner build only)
* fix(layout): the timeout take-back keeps a pane whose terminal started or is starting (dark, layout-owner build only)
* fix(layout): one take-back call keeps the layout-writer count
* fix(layout): a split take-back is decided in the write queue, and a spawn for a taken-back pane starts nothing (dark, layout-owner build only)
* test(layout): a spawn for a taken-back pane is refused before the provider spawns
* test: typed store fake in the closed-pane spawn test, no casts
* fix(layout): a CLI split whose pane main closes before it mounts answers at once (dark, layout-owner build only)
* test(layout): the closed-before-mount split fails because of the close
