fixup: Bump typescript from 5.9.3 to 6.0.3

Fix TypeScript 6.0 compatibility

- Update main tsconfig: remove baseUrl, update moduleResolution to bundler
- Update webview tsconfig: add lib es2017, disable strict checks
- Add ambient.d.ts for asset module declarations (.scss, .png, etc.)
- Add VscodeAPI type declaration
- Set ignoreDeprecations to 6.0 to silence deprecation warnings

Fixes build errors after upgrading from TypeScript 5.9.3 to 6.0.3
