i18n: complete Simplified Chinese catalog, Chinese font fallback and a coverage xtask (#930)

Adds a complete Simplified Chinese (zh) catalog covering every English message, a font fallback for Chinese text, and `cargo xtask i18n --check`, which checks that the complete catalogs (ja, zh) carry every English message and that every command label is translatable.

+## Coverage
+
+A message a locale never received falls back to English silently, so a gap shows up only as a row
+that looks untranslated. Two guards catch that in the build:
+
+- `every_complete_catalog_carries_every_english_message` — adding a key to `en.json`
+  without giving it to a complete catalog fails the tests. English is the source catalog,
+  Japanese and Chinese are delivered complete; German and Korean are still partial — their
+  gaps are reported by `cargo xtask i18n` without failing the build.
+- `every_toolbar_tab_and_panel_is_in_the_english_catalog` — tabs and panels reach the UI as bare
+  source strings, resolved only by the English-label adapter, so a heading missing from `en.json`
+  can never translate.
+
+Command labels are the same case on a larger scale: every label in the engine's registry now has
+an entry under `cmd.<command id>`, and `every_command_label_is_in_the_english_catalog` fails if a
+command is added without one.
+
+The context menu and the browser are the same case again, and they carry the most labels of all:
+`every_menu_label_is_in_the_english_catalog` opens every menu the app can reach, flips the state
+each conditional label branches on (origin shown, bodies locked, bodies hidden) so both branches
+are seen, and fails on any label the catalog has never seen. Unit symbols are left out of the
+sweep: `mm` is `mm` in every language, so they are not prose to translate. The sweep also asserts
+it keeps reaching a broad set of labels, so it cannot pass by finding nothing.
+
+`cargo xtask i18n` prints the same picture across every locale — which messages each one is
+missing and which command labels English cannot translate. `--check` turns it into a non-zero exit
+for CI. `--add-missing` writes each uncovered label into `en.json` under `cmd.<command id>`, with
+the English label as its text, so the label adapter can find it and only the translations are left

+//! `cargo xtask i18n`: the message catalogs' coverage report, and a way to repair it.
+//!
+//! The catalogs under `crates/ui-egui/src/locales` are plain JSON maps from a stable message id
+//! to one translation. The English catalog is also the lookup table for `Locale::label()`, which
+//! translates source strings coming from the engine (command labels, toolbar tabs and panels) by
+//! matching their English text. A label the English catalog does not carry therefore stays English
+//! in *every* locale, silently — nothing fails, the row just looks untranslated.
+//!
+//! That is the failure this command exists to make visible. `--check` turns the report into a
+//! non-zero exit for CI; `--add-missing` writes the uncovered command labels into the English
+//! catalog under `cmd.<command id>` so a translator only has to fill in the other catalogs.
+//!
+//! German and Korean predate the coverage guards and are still partial, so their gaps are
+//! reported but do not fail `--check`; the catalogs delivered complete (`COMPLETE`) may not
+//! regress.
