Jinwoo Hong a40ae0ce5a Close, rename and equalize panes through main (dark, build switch off by default) (#29187)
* feat(layout): add the dark layout.apply channel and route pane splits through main behind ORCA_LAYOUT_OWNER

A build made with ORCA_LAYOUT_OWNER=main registers layout.apply: main applies the
window's layout command to the stored partition through the shared applyLayoutCommand,
minting new ids. A user split then waits for main's answer and mounts the pane id main
minted. Every other build substitutes 'window', so neither branch is compiled in.

* fix(layout): write only the records a layout.apply command touched

A load-then-save rewrite also normalizes records the command never touched. The command's
effect is now the diff between the save before and after it, written onto the stored
partition record by record. A split whose main reply says a paired server holds the tab
splits as today.

* fix(layout): write a load-supplied record whole and check that patched partitions reload to the command's result

* feat(layout): close, rename and equalize panes through main behind ORCA_LAYOUT_OWNER

In a layout-owner build the window's pane close, title change and equalize go through
layout.apply and the window shows main's answer. A window pane close keeps the legacy
close's rules: the tab's last pane is refused, a pane restarted since main read the close is
left alone, every partition holding the tab closes it, and the tab's remote session id follows
the remaining pane. The rules sit behind a command field only layout.apply sets.

* fix(layout): close the tab when a racing pane close leaves the window one pane

* fix(layout): leave an unmounted tab alone when main refuses its last pane

* fix(layout): close a user's pane even if its terminal restarted, as today

* test(layout): pin the restarted-pane close directly, not through a made-up profile state

* fix(layout): leave a split to today's path only when the workspace's row names a paired server

The split switch point asked which host to route to with a helper that falls back to the focused
server, so a focused server could claim a workspace whose row names no owner. Use the same owner
test the tab mirror uses.

* test(layout): type the split owner mock without a cast

* test(layout): type the layout-owner command mocks with the real signature

* fix(layout): finish the main merge with this branch's versions of the layout-owner files
