/**
 * Internal URL parser that handles colons in the host segment.
 *
 * Standard `new URL()` interprets colons as port separators, which breaks
 * namespaced internal URLs like `skill://plugin:name`. This parser extracts
 * components via regex first, then falls back to a minimal URL-like object
 * when `new URL()` fails.
 *
 * All code that parses internal URLs (router, protocol handlers, tools)
 * MUST use this function instead of calling `new URL()` directly.
