Can I vibecode Zight?

Build a lightning-fast, highly polished personal replacement for Zight (formerly CloudApp) in an empty repository.
Use exactly this stack: Tauri 2, React, TypeScript, ffmpeg, and SQLite; do not offer alternative stacks.

Primary Objective: Create a seamless desktop application for visual communication that captures screen recordings, GIFs, and high-quality screenshots, provides robust annotation tools, and allows for instant local saving or generation of a shareable hosted link (via a user-provided S3/R2 bucket, not a proprietary cloud).

Detailed Feature Requirements:
1. Versatile Screen & Video Recording: Implement robust capture modes including full screen, specific window, and custom region selection. Support simultaneous webcam overlay (picture-in-picture) and optional microphone audio. Ensure 4K recording capabilities using optimized `ffmpeg` presets (H.264/WebM).
2. Instant GIF Maker: Provide a one-click toggle to convert short screen recordings directly into lightweight, optimized GIFs for easy sharing in chat applications.
3. Advanced Annotation Studio: Build an intuitive built-in editor that opens immediately after a screenshot or video capture. Include tools for drawing arrows, adding text, shapes, highlighters, and a crucial blur tool to quickly obscure sensitive information (passwords, PII).
4. AI-Ready Summarization (Optional hook): Generate a smart poster frame for videos. Provide a local hook or simple API integration point where a user could plug in a local transcription model (like Whisper) to generate "Smart Chapters" or a Markdown summary of the video.
5. Bring-Your-Own-Cloud Sharing: Instead of mandatory proprietary cloud upload, allow the user to configure their own S3-compatible storage (AWS, Cloudflare R2, Backblaze) in the `.env` file. Upon capture, optionally auto-upload and instantly copy a shareable public URL to the clipboard.
6. Local Library & Quick Actions: Maintain a searchable, visually appealing gallery of all past captures in SQLite. Provide instant "copy file path", "reveal in folder", and "drag-and-drop to other apps" functionality.

Strict Constraints:
- Make the first run work locally with one documented command.
- Store all user data locally by default. Never commit credentials.
- Show an always-visible recording timer and allow stopping from the system tray.
- Deliberately leave out: public proprietary cloud hosting, viewer identity/engagement analytics, enterprise workspaces, and SSO.
- Include clear empty, loading, success, and recoverable error states.
- Handle unavailable external APIs gracefully (fallback to local-only mode).
- Write focused tests for the core video transformation and one end-to-end happy path.
- Create a comprehensive README with setup, permissions, architecture, and backup instructions.
- Finish by running tests and fixing any errors.
