…#63748) cc @shuding ### Why? The typescript plugin in #63667 does not target the call expression or assigned actions. ```ts 'use server' function action() { return async function() { return 'foo' } } async function action2() { return 'foo' } export const callAction = action() // call expression export const assignedAction = action2 // assigned ``` ### Current  ### Fixed  x-ref: #63667 Closes #63743

For problems like #62821, #62860 and other, the only way to improve the DX would be relying on the type checker to ensure that Server Actions are async functions. Inlined definitions will always be checked by SWC (as they're always syntactically defined as functions already), but export values are sometimes determined at the runtime.
Also added
react-domrelated methods to the disallow list for the server layer.Examples:
