Function resolveUrl

resolveUrl(relative: string, base: string): string
Resolves a relative URI against a base URL using string manipulation, avoiding the overhead of constructing URL objects.

Handles the same cases as new URL(relative, base):
- Absolute URIs (with scheme) are returned as-is.
- Protocol-relative URIs (//host/path) inherit the base scheme.
- Absolute paths (/path) replace the base path.
- Relative paths are resolved against the base directory.
Parameters
- relative: string
  The relative (or absolute) URI to resolve.
- base: string
  The base URL string to resolve against.
Returns string
A resolved absolute URL string.
