Replace sharp with wasm-vips for image processing
Fixes #696 - Replaced sharp dependency with wasm-vips (WebAssembly build of libvips) - Eliminates native build requirements that caused installation failures - Added vips.ts singleton wrapper for async initialization - Updated image-resize.ts and image-convert.ts to use wasm-vips API - Added unit tests for image processing functionality

### Changed
|
||||
|
||||
- Light theme colors adjusted for WCAG AA compliance (4.5:1 contrast ratio against white backgrounds)
|
||||
- Replaced `sharp` with `wasm-vips` for image processing (resize, PNG conversion). Eliminates native build requirements that caused installation failures on some systems. ([#696](https://github.com/badlogic/pi-mono/issues/696))
