fix(es/parser): isolate enum await context (#12506) **Description:** An enum initializer such as `enum E { await = 1, X = await }` is incorrectly rejected inside an async function or module. Parse enum bodies with their own declaration grammar while preserving await restrictions in enclosing scopes and nested async functions. Includes a patch changeset for `swc_ecma_parser` and `swc_core`. **Related issue (if exists):** - Close #12511

fix(es/codegen): parenthesize typed arrow parameters (#12503) **Description:** Minifying `const f = (x: number) => x` can produce `const f=x:number=>x`, which is invalid TypeScript. Preserve required parentheses for typed or optional parameters, return annotations, and generic arrows. Includes a patch changeset for `swc_ecma_codegen` and `swc_core`. **Related issue (if exists):** - Close #12508

fix(es/parser): isolate enum await context Enum members can reject await identifiers under enclosing async or module grammar and misclassify escaped contextual operands. Give enum bodies independent Await/Yield parameters. Distinguish escaped operands from unescaped type operators during recovery while preserving nested function and loop restrictions.

fix(es/parser): allow namespace await identifiers File-level await reservation rejects identifiers inside TypeScript namespaces, and recovery can misread escaped contextual operands. Scope namespace grammar while preserving inherited Await/Yield and strictness. Restore outer state and distinguish escaped operands from unescaped type operators during recovery.
