feat: prepare desktop editors, recording reliability and diagnostics

[richiemcilroy]

Both desktop editors now support timed style and image tracks, saved ordering across text/image/mask layers, 3D scene controls, and consistent caption and keyboard timing through cuts. Preview and export use the saved project configuration, and late GPUI export previews cannot replace a newer request or a reopened window.

The release also includes recording quality controls, browser-based pricing, safer device and permission lifecycles, bounded recording shutdown and recovery, structured operation diagnostics, and safer native save/export behavior. Linux camera, Wayland capture/Stop handling and installed ONNX Runtime lookup are included, along with macOS 12.3 packaging and the camera enumeration fixes from #2248. The structured diagnostic upload endpoint is in #2252. Desktop release notes are included.

Validation: 351 desktop frontend tests, 922 GPUI tests and 859 tests across Tauri, project configuration, rendering, camera effects and utilities pass. Seven shared-crate tests and one GPUI test remain intentionally ignored by their existing suites. Forty-seven packaging tests, desktop TypeScript, scoped Biome, root/GPUI formatting and desktop frontend production build pass. Both native applications compile with all test targets. CI-equivalent workspace Clippy with all features and warnings denied passes on macOS. Tauri bindings were regenerated with typescript_bindings_tests::export_typescript_bindings, and the frontend build regenerated the icon declarations. One existing upload scheduling test needed lower test concurrency to meet its timing threshold.

The final snapshot comparison preserved the original editor control bindings and overlay rows. Stop requests now release their pending state on completion and retain errors, with regressions for retry and stale completion. Forty-two GPUI timeline tests and the frontend production build pass after those corrections.

Build metadata probes use explicit system Git paths. Custom installations can set CAP_BUILD_GIT to an absolute executable path. An executable shadowing Git on PATH and a relative override are both rejected; native checks and Clippy pass.

Greptile reached a fresh 5/5 on this revision with no unresolved review threads. All current CI checks pass, including macOS, Windows and Linux desktop builds, platform Clippy, synchronization tests, typechecking and security scans. Packaged native UI, low-storage Stop/recovery/Quit, signed packages/updater behavior and A/V performance remain release validation gates; local compilation and unit tests do not establish those results.

Confidence Score: 5/5

The PR appears safe to merge based on the reviewed changes, with no outstanding blocking findings.

Summary

• Adds timed style and image tracks, persistent layer ordering, 3D scene controls, and cut-aware caption and keyboard timing.
• Improves recording shutdown, recovery, permissions, native save/export behavior, and operation diagnostics.
• Adds Linux camera and Wayland support, installed ONNX Runtime discovery, macOS 12.3 packaging, and broader release validation.
• The latest revision hardens build metadata collection by using explicit Git executable paths and an absolute CAP_BUILD_GIT override.
