[F] setAutoDecorator

function setAutoDecorator(
   program,
   decoratorFqn,
   target,
   value?): void;

Programmatically apply an auto decorator to a target, storing its argument values.

Mirrors what the synthesized auto dec implementation does when the decorator is written in source, so emitters and mutators can mark synthetic types the same way without reaching into the program state map directly.

Parameters

Parameter	Type	Description
`program`	`Program`	The current program.
`decoratorFqn`	`string`	The fully-qualified name of the decorator (e.g., “MyLib.myDec”).
`target`	`Type`	The type to mark.
`value`	`Record`<`string`, `unknown`>	The stored `{ paramName: value }` record (defaults to `{}` for a no-arg decorator).

Returns

void
