Add QR pairing auto-connect and improve compatibility/codec selection
- Add a QR pairing workflow in the device pairing UI, including generated temporary QR credentials, method switching (QR vs pairing code), and automatic pairing when the target pairing service is discovered over mDNS.
- Update pairing entrypoints so both QR and pairing-code paths share a single validation/connection flow, support discoverable host+port prefill from nearby services, and improve pairing-state transitions.
- Refine compatibility-mode session behavior by removing forced clipboard-sync disablement while preserving the existing audio-disable invariant; allow multiple connection candidates to surface explicitly.
- Update automatic video codec selection to prefer Google VP8 over Google H264 in the constrained Google-only fallback path when no user codec is selected, with VP8 fallback handling to H264 if VP8 decode is not available.
- Add/update targeted unit tests for pairing, compatibility mode, and codec selection behavior, and keep runtime/build contract updates aligned with the new behavior.

Harden compatibility input and video recovery
- Stream compatibility-mode touch events through the bundled helper with bounded MOVE coalescing and interrupted-stream recovery.
- Expand video recovery through maxSize 540, cancel conflicting reconnects, and show actionable session-aware failures.
- Move management dashboards and icon caching to typed helper snapshots and version metadata.
- Update AGP to 9.3.1 and add focused coverage for connection display, helper caching, touch queues, runtime state, and video recovery.
Screen-Remote-Review: confirmed
## Add URL automation and compatibility recovery
- Add screen-remote URLs for navigation, transient scrcpy overrides, management, and settings.
- Add an ADB screenshot compatibility mode with user-confirmed video capture and decoder-size recovery.
- Add opt-out telemetry, debug diagnostics, media hardening, remote volume-key forwarding, and regression coverage.
## Add legacy shell fallback and remote device helpers
- Fall back from shell_v2 to legacy shell when unsupported or rejected, and remember rejected connection features.
- Add a remote JPEG screenshot stream with DisplaySurface and SurfaceControl capture backends.
- Add helper APIs for directory listing, process inspection, application metadata, icons, and remote text injection.
- Extend compatibility to older Android runtimes and replace unavailable platform APIs with portable implementations.
- Add regression and integration coverage for legacy shell, management helpers, screenshots, and platform compatibility.
## Standardize runtime diagnostics in English
- Replace Chinese and locale-dependent internal diagnostics across logging, ADB, media, scrcpy, session, control, and foreground-service paths with fixed English text.
- Align reconnect permanence matching and stream-closure detection with the translated error messages while preserving runtime flow.
## Unify ADB routing and improve management and decoder recovery
- Separate primary and delayed-ACK streaming routes in DadbSession, isolating resource ownership between scrcpy forwarding and regular management operations
- Preload and cache app and file data, improve terminal interruption, history, and semantic highlighting, unify semantic colors across themes, and normalize an empty game-mode bitrate to 2 Mbps
- Replay a bounded complete GOP after decoder switches and add regression tests, introduce the manual pre-push Wiki review gate, and bump the version code to 7
