Minor Changes - BREAKING CHANGE: Make search param pattern decoding and serialization consistent with `URLSearchParams`. Affects: `RoutePattern.{match,href,search,ast.search}` Previously, `RoutePattern` treated `?q` and `?q=` as different constraints: ```ts // Before: `?q` and `?q=` are different let url = new URL(' // Matches "key only" constraint? new RoutePattern('?q').match(url) // ✅ match // Matches "key and value" constraint? new RoutePattern('?q=').match(url) // ❌ no match (`null`) // Different constraints serialized to different strings new RoutePattern('?q').search // -> 'q' new RoutePattern('?q=').search // -> 'q=' ``` There were two main problems with that approach: Unintuitive matching ```ts // URL search looks like `?q=` let url = new URL(' // Pattern search looks like `?q=` let pattern = new RoutePattern('?q=') // But "key and value" constraint doesn't match! pattern.match(url) // ❌ no match (`null`) ``` Parsing and serialization For consistency with `URLSearchParams`, search param patterns should be parsed according to the WHATWG `application/x-www-form-urlencoded` parsing spec and should also encode spaces as `+`. Now, we use `URLSearchParams` to parse search param patterns to g
