Merge main into Pallet-placement

Resolved conflicts:
- app/update/mod.rs: keep the dock's dock_open_at_default for the XREF
  manager; take main's stable xref row identity (row_index(&id)).
- app/view/mod.rs: keep the edge layout from app::dock; drop main's copy
  of the old edge-stack code (main only reformatted it there).
- ui/window/layers.rs: keep main's new visible_indices next to the
  branch's view_panel.
Files the branch only reformatted take main's version. Adds the Lao
(lo-LA) translations for the new dock texts.

 `ocs_capture` defaults to the drawing viewport and a longest edge of 1600 pixels. Set `scope` to `window` for the full interface or change `max_dimension` between 256 and 4096.
 
+With `diff: true`, an unchanged comparison returns metadata only, including
+`diff.changed: false`, the hash and resource URI; it does not resend image or
+resource content blocks, regardless of `delivery`. The initial baseline (also
+after `reset_diff_baseline: true`) still uses the requested image delivery.
+Changed captures retain the requested diff mode, including cropped patches.
+Use `diff: false` or read the returned resource URI to retrieve the full image

 Clients using MCP 2026-07-28 can advertise `io.modelcontextprotocol/tasks`. OCS then returns a standard task handle when an operation is still running and accepts `tasks/get`, `tasks/update`, and `tasks/cancel`. Other clients continue to receive the existing operation status and can read it with `ocs_read`.
 
 The source-tree protocol smoke test treats the executable as a black box and uses only the Python standard library. It checks both supported protocol styles, the published schemas, structured errors, and the four-tool surface:

+1. ດາວໂຫຼດ `OpenCADStudio-*-macos-arm64.dmg`.
+2. ເປີດດິສອິມເມດ ແລະ ລາກ `OpenCADStudio.app` ໄປໃສ່ໂຟນເດີ **Applications**.
+3. ຖ້າ Gatekeeper ບລັອກການເປີດຄັ້ງທຳອິດ, ໃຫ້ອະນຸມັດແອັບໃນ **System Settings → Privacy & Security**.

+
+ປ່ຽນພາສາໄດ້ໃນການຕັ້ງຄ່າຂອງແອັບ. ເມື່ອເລືອກ **ລະບົບ**, ລຸ້ນບຣາວເຊີຈະໃຊ້ພາສາທີ່ບຣາວເຊີຕັ້ງໄວ້.
