v0.1.0-alpha.1

Summary

First public alpha of WVC-CAD after the review-brief P0/P1 pass.

• Real Save / Save As / recent files (File System Access + Tauri dialog/fs)
• Autosave quota safety, multi-window writer id, Tauri close confirm
• Hardened .sketch.json loader (limits, NaN/Infinity, fuzz)
• Original app icons + CSP
• Sample sketches under File → Sample… and first-run tip

Install

Windows NSIS setup attaches when the Tauri build finishes (unsigned — SmartScreen may warn; see PACKAGING.md).
MSI is deferred for this alpha: WiX requires a numeric-only prerelease segment.

Try without installer

npm install && npm run dev — open a sample from the File menu.

Known

Dimension presentation can look a bit odd; that can be tightened in a follow-up.
