Feature/save load localstorage

[Flux07-gezz]

Description

This PR introduces a client-side project state serialization and restoration framework utilizing browser localStorage under the versioned key reframe-projects-v1. Because Reframe functions as a static export application, this enables persistent timeline editing progress across browser reloads without requiring an external database backend.

Key Changes:

• src/hooks/useVideoEditor.ts: Created saveProject(), listProjects(), loadProject(), and deleteProject() hooks wrapped in safe error boundaries to avoid browser storage quota crashes.
• src/components/VideoEditor.tsx: Constructed clean, responsive Save and Load action modals matching Reframe's structural design language.
• Accessibility & Linting Fixes: Refactored layout container rows inside the modal loops to use semantically accurate html interactive buttons to pass strict jsx-a11y/click-events-have-key-events and no-static-element-interactions checks. Removed autoFocus hooks to maintain cross-device usability.

Note: Due to standard browser memory limitations, raw video binary files/blobs are intentionally not stringified. A dynamic UX callout banner has been integrated into the restoration modal to remind users to re-select their source file after state hydration.

Hey @magic-peach! 👋

Just wanted to give you a heads-up that PR #754 is ready for review — it implements the save/load project state feature using localStorage (closes #686 and #688) .

Here's a quick summary of what's in it:

• saveProject(), listProjects(), loadProject(), deleteProject() added to useVideoEditor.ts
• Modal-based Save and Load UI in VideoEditor.tsx
• SSR-safe localStorage access with typeof window guards
• Full error handling for private browsing / quota exceeded
• Schema versioning (schemaVersion: "v1") and savedAt timestamps for future migrations
• Warning shown to users that the video file needs to be re-selected after loading

All CI checks are passing. Would love to get your feedback whenever you get a chance! 🙏
