Record the local-build pin in the OmarchyCN shipping prerequisites

 - The region screen, Rime bundling and local `rime-ice-installer` build exist only on the `omarchycn` branches: a China-ready ISO is built by running `./bin/omarchy-iso-make --local-source ../omarchy ../omarchy-pkgs` from `omarchy-iso/` until they are merged and published.
 - omarchy-pkgs PR 265 (rime-ice-installer) must merge, with `omarchy-offline.patch` upstreamed to manateelazycat/rime-ice-installer, before non-local ISO builds can list it.
 - omarchy-iso PR 210 (stop passing `offline` to archinstall 4.5's `sanity_check`) is cherry-picked on `omarchy-iso/omarchycn`; the edge snapshot already ships archinstall 4.5.
+- A local-source ISO builds `omarchy-dev` and `omarchy-settings-dev` under the published version number, so the next edge release would replace them with builds that lack the China code. Until these branches ship upstream, the ISO pins the local builds with `IgnorePkg` and a `pre-refresh-pacman` hook (omarchy-iso README). Pinned machines get no Omarchy updates.
 - `stable-mirror.omarchy.cn`, `rc-mirror.omarchy.cn` and `mirror.omarchy.cn` must resolve for Arch packages to come from China; until then pacman falls through to `.org`.

 | # | Requirement | Result | Evidence |
 |---|---|---|---|
-| 1 | China package sources: `pkgs.omarchy.cn` before `.org`, Arch `.cn` mirrors before `.org`, `omarchy update` keeps them | Pass | China install has a `.cn` twin above each `.org` server in `pacman.conf` and `mirrorlist`; `omarchy update -y` keeps them; `region-test.sh`, `region-switch-test.sh`. Arch `.cn` hosts do not resolve yet, so pacman falls through to `.org`. |

 | 2 | Region choice on the installer's first screen | Pass | Configurator asks Global/China before the keyboard; summary shows the region; `test_region.py`, `setup-form-test.sh`; both QEMU installs answered it. |
 | 3 | Chinese input ready at first login, Ctrl+Space toggles | Pass | China install: Rime Ice and the Wanxiang model from the ISO, no prompt; after reboot Ctrl+Space typed 中文, then Ctrl+Space typed `ok`. Global install has no Rime. |
 | 4 | CJK font fix (PR 9693) | Pass | `50-omarchy.conf` rebuilt; `fontconfig-cjk-test.sh` covers fc-match and the string lang path apps use; China VM resolves SC, JP and Latin mono as expected. |
