Desktop settings mixed nested experiments with debug tools, while native live input and update checks had unreliable ownership and fallback behavior. This change makes advanced features peer pages, hardens live input and update discovery, and restores the established capsule and switch geometry after correcting unintended visual changes.

• Simplifies advanced settings and removes the retired desktop agent UI and IPC. Existing preference and wire fields remain readable.
• Preserves the original recording capsule size, rounded controls, switch shapes and native trackpad momentum. Translation controls retain their updated corner treatment. Segmented indicators animate without distorting their shape; dropdowns retain their edges, visible backgrounds and keyboard focus feedback. The history list has a continuous rounded surface and the correction-rule add button uses an 8 px radius.
• Guards Enter during IME composition and for 500 ms afterwards. QA message following respects manual scrolling, with a visible jump-to-latest control beyond 120 px.
• Validates macOS live replacement ownership, selection, focus and application identity; lost targets fall back to copying. Native capsule input is limited to visible controls and open menus, separately for each mirror.
• Discovers updates from GitHub and Aliyun concurrently, including rate-limit fallback and version-aware source selection, while retaining signature verification.
• Releases inactive rendering resources and improves the cross-platform CI, cache and packaging workflows.

Validation on 405d1afb (application source matches 5427c49d; the last commit only updates a test):

• TypeScript, production build and 165 frontend test files passed locally.
• Chromium and WebKit: 54 focused capsule, control geometry, settings and motion tests passed; the WebKit 90% zoom case passed 10 repeated runs without ResizeObserver errors. Earlier focused navigation, scrolling and fallback tests passed.
• Native macOS main and mirror GUI acceptance passed on the final source, including the restored 116 × 32 capsule, original button shapes, transparent click-through, confirm/cancel and language selection. All applicable checks passed: cross-platform CI and iOS CI. The branch-only Linux publishing job was skipped as intended.
• Earlier native input, updater, packaging and full CI evidence is retained in the PR history; it does not establish the result for the current commit.

The installed application is not replaced and this PR does not publish a release.
