Adds a new Svelte store under source/components to track the current GitHub page URL in SPA navigation flows. The stored value is hashless, and hash-only transitions do not trigger updates.

• Store implementation

  • Added source/components/url.ts with a readable store that normalizes URL values by removing #....
  • Exposes the current canonical URL (including pathname/search, excluding hash).

• SPA navigation coverage

  • Updates on history.pushState, history.replaceState, and popstate.
  • Also listens to navigation.navigate when the Navigation API is available.

• Update semantics

  • Emits only when the normalized URL changes, so fragment-only changes are ignored.

function normalizeUrl(url: string): string {
	const parsed = new URL(url, location.origin);
	parsed.hash = '';
	return parsed.href;
}

• Tests
  • Added source/components/url.test.ts covering:
    • initial hash stripping
    • push/replace updates
    • hash-only no-op behavior
    • popstate handling
    • Navigation API handling
