* 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

* 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
