fix(es/fixer): preserve TypeScript expression grouping Preserve required parentheses for TypeScript casts in conditionals and instantiation expressions before binary operators. Keep `await` and type assertions grouped on the left of exponentiation. Scope TypeScript lookahead state to each operand and add TS/TSX fixtures.

fix(es/parser): isolate function names in async arrow parameters Suspend await collection while parsing function expression names so nested names do not trigger the enclosing async arrow parameter check. Add fixtures for ordinary and generator names and collection restoration.

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.
