Localizes the GPUI editor shell so a non-English system no longer sees English in the editor once the language picker ships in 0.6.2.

What was converted

545 new catalog keys under editor.window.*, editor.export.*, editor.clips.*, editor.timeline.*, editor.tabs.*, editor.canvas.*, editor.modal.* and ui.*, with translations in all six catalogs (zh-CN, ja, fr, es, de, hi) that follow GLOSSARY.md.

• Editor window (editor_window.rs, editor_window/): header and toolbar buttons and tooltips, aspect ratio and preview quality labels, transport tooltips, the clip and text context menus, presets menu and dialogs, the add-track popover, zoom and 3D lane prompts, frame picker, the "could not be opened" screen and its preflight errors, deletion and close blockers, title save errors, audio and image import errors, and the file dialog filter names.
• Export dialog (editor_export.rs): every section, segmented option, toggle, stat, progress heading, completion state, the cancel and resource confirmations, upload failure dialogs, and the size and time estimates. Estimates keep their numeric formatting; only the units and the ~ and < wording come from the catalog.
• Clips (editor_clips.rs): the sidebar, import menu, rfd filter names, the import and append error dialogs (titles and bodies), the clip and split default names, and the user-facing import errors.
• Timeline (editor_timeline.rs): track names, track picker descriptions, the remove-track hints, empty lanes, segment labels, scene modes and badges.
• Editor tabs (editor_tabs.rs): the camera, audio, cursor, keyboard, captions and sync tabs, including every menu catalogue (shapes, blur modes, corner styles, stereo modes, cursor styles, weights, positions, caption animations, highlight styles, caption languages, caption models and presets).
• Canvas, modal and ui helpers: canvas selection labels and lock hints, the export cancel modal, the "Recording retained" alert, SelectionHeader and the Coming Soon tooltip.

The selection header used to build "{count} {noun} segment{s} selected". It is now one plural message per noun (ui.selection.*), and the zoom header's All {count} / {count} of {total} / {count} forms are plural messages too. selection_label still takes the same noun strings, so editor_panels.rs is untouched. "Remove the {track} track." is now one message per track (TrackKind::picker_remove) instead of a sentence wrapped around a translated label.

The const catalogues hold fn() -> &'static str instead of &str, so a label is read in the current language each time a menu or row is drawn. The timeline model keeps placeholder names (untitled text, caption and audio segments, clip numbers, mask kinds), so EditorWindow rebuilds it when the language changes. The frame title and preset name placeholders are set on render rather than once at creation.

Left in English on purpose

• "Export cancelled" and the other control-flow comparisons in editor_export.rs.
• Clock and duration formatters (format_time, format_clip_time, format_duration, slider readouts in ms and s).
• Font family names (FONT_OPTIONS), keyboard key names (kbd.rs, Space, Esc), product names (Cap, Studio, Instant, Studio Sound, the PRO badge), OS names in the frame picker (macOS, Windows, MacBook), format names (MP4, GIF, 720p, 4K) and model engine names.
• Persisted values: the Cap Recording export file name fallback, the Audio name stored on imported audio segments, export prefs.
• Internal and technical errors that only reach logs or wrap engine text: thumbnail decode, ffmpeg probing, metadata save, the preparing pipeline, and the disk check messages built in cap_utils::export_resources, which Tauri shares.
• The Make it pop caption preset preview words.

Layout

Segmented controls that stretch (the export dialog's destination and quality rows) now truncate their labels instead of overflowing, and the export stats card truncates its labels. English fits as before, so nothing moves for English.

How English was proven unchanged

• src/i18n/editor_shell_surface_tests.rs pins every plain key to the literal it replaced (484 pairs, counted against the catalog so a new key without a pair fails) and checks every parameterized message against the format! it replaced, with plural cases 0, 1, 2 and 5. It also checks the per-noun selection labels and the remove-track hints against the old assembled sentences.
• editor_export.rs gained a test that pins format_estimate_range output.
• Every plain English value was checked against the literals in the pre-change sources; the only values not found verbatim are the derived ones covered by the tests above.
• src/i18n/tests.rs gets one filter line so these keys are counted by the new test file instead.

CI

CI run 40383143384 on 92f1aac is green: GPUI builds and cap-gpui tests on macOS (arm64 and Intel), Windows and Linux, cap-i18n-build tests, Format (Cargo), Typecheck and Biome. The root-workspace Clippy and Rust test jobs are skipped by path filters because no root crate changed.

Confidence Score: 5/5

The changes since the previous review appear safe to merge.

Summary

Localizes the GPUI editor, export dialog, clips, timeline, and tabs, with translated catalogs and English text checks.

• Editor controls and timelines show labels in the selected language.
• More app screens and native menus follow the selected language.
