fix(es/parser): handle Flow async generic arrows (#11926) **Description:** Fixes two Flow parser gaps reported in #11925: - Parse async generic arrows with typed params and explicit return annotations, such as `async <T>(x: T): Promise<T> => x`. - Parse anonymous function-type parameters in `declare class` method signatures, preserving the existing `__flow_anon_param_N` synthetic parameter convention. - Adds focused Flow parser fixtures for both cases. Validated with: - `cargo fmt --all` - `cargo test -p swc_ecma_parser` - `cargo test -p swc_ecma_parser --features flow --test flow -- --ignored` - `cargo test -p swc_ecma_transforms_typescript flow_strip_reparses_as_javascript -- --ignored` - `cargo test -p swc_ecma_parser --features flow --test flow_hermes` - `cargo clippy --all --all-targets -- -D warnings` **Related issue:** Fixes #11925

fix(es/minifier): handle unknown member props (#11927) **Description:** Fixes a build failure when `swc_ecma_minifier` is compiled with `RUSTFLAGS="--cfg swc_ast_unknown"`. With `swc_ast_unknown`, `MemberProp` is treated as non-exhaustive, so the hoisted property replacement match in the minifier needs to account for future or unknown variants. Unknown member props now simply skip this optimization path, preserving the original expression and normal traversal behavior. Also adds a patch changeset for `swc_ecma_minifier` and `swc_core`. Validated with: - `RUSTFLAGS="--cfg swc_ast_unknown" cargo check -p swc_ecma_minifier` - `git submodule update --init --recursive` - `cargo fmt --all` - `cargo test -p swc_ecma_minifier` - `cargo clippy --all --all-targets -- -D warnings` **Related issue:** Closes #11910
