/**
 * Creates a `paramsAtom` computed from `pathAtom` + the matched route pattern
 * (`patternsAtom`).
 *
 * Kept synchronous (not `atom(() => …)`) so that when the router sets
 * `patternsAtom` during a template render, `paramsAtom` already reflects the
 * new params for that same render pass.
 *
 * Public `set` / `update` are wired to `navigateTo` (via buildPath) in
 * RouterUtils. Internal sync uses `originalSet`.
 *
 * @example
 * const paramsAtom = createParamsAtom(pathAtom, patternsAtom);
 * // patternsAtom = "/users/:id", path = "/users/42" → { id: "42" }
