Browsers like Safari and Edge on macOS require icons with purpose "any" to display the app icon when installed as a desktop app.
Previously, only "maskable" purpose icons were declared, causing a generic icon to appear instead of the JetKVM logo.
Fixes#816
Add SVG and ICO to cacheable files.
Emit robots.txt directly.
Recognize WOFF2 (font) files as assets (so the get the immutable treatment)
Pre-gzip the entire /static/ directory (not just /static/assets/) and include SVG, ICO, and HTML files
Ensure fonts.css is processed by vite/rollup so that the preload and css reference the same immutable files (which get long-cached with hashes)
Add CircularXXWeb-Black to the preload list as it is used in the hot-path.
Handle system-driven color-scheme changes from dark to light correctly.
