Wire together all Phase 8 components into the browser's navigation flow:
- Use css_loader::collect_stylesheets for external <link> and inline <style>
- Use img_loader::collect_images to fetch and decode <img> elements
- Store pre-fetched PageState (DOM, stylesheet, images) so window resizes
only re-style/re-layout/re-render without re-fetching
- Show error page for network failures instead of process::exit
- Preserve base URL from HTTP response for resolving relative subresources
- Generate file:// base URL for local file paths

Add about: scheme handling to ResourceLoader:
- Recognize about:blank and return a minimal empty HTML document
(<!DOCTYPE html><html><head></head><body></body></html>)
- UTF-8 encoding, no network requests
- Unsupported about: URLs return InvalidUrl error
Update browser main to use about:blank as default:
- No URL argument opens about:blank instead of hardcoded demo page
- URL arguments (http://, https://, about:, data:) load via ResourceLoader
- File path arguments still work as before
4 tests covering fetch/fetch_url paths, DOM structure validation,
and unsupported about: URL rejection.

Add data_url module to the url crate:
- Base64 decoder (RFC 4648): standard alphabet, whitespace stripping, padding
- Data URL parser: extract MIME type, charset, base64/percent-encoded payload
- Default MIME type text/plain;charset=US-ASCII when omitted
Integrate with ResourceLoader in browser crate:
- Handle data: URLs in both fetch() and fetch_url() without network access
- Classify decoded content into Html/Css/Image/Other resource types
- Decode text resources using charset from data URL parameters
44 tests covering base64 decoding, data URL parsing, MIME extraction,
percent decoding, and ResourceLoader integration.
