/**
 * Match a request path against a Trigger path with OpenAPI-style
 * `{param}` segments. Returns the extracted params on a match, or
 * `null` if the segments don't line up.
 *
 *   matchPath("/api/contact", "/api/contact")       → {}
 *   matchPath("/api/posts/{id}", "/api/posts/abc")  → { id: "abc" }
 *   matchPath("/api/posts/{id}", "/api/posts")      → null
 *   matchPath("/api/posts", "/api/posts/abc")       → null
 *
 * Pure path math — no I/O. Lives in `domain/service/` so adapters
 * (HTTP layer) can call it without dragging an HTTP framework dep.
