`@__KEY__` and `#__KEY__` are currently treated as normal comments. Codegen can drop them before a later property-mangling pass. The property may then be renamed while the annotated string keeps its old name.
This classifies the marker as a property-key annotation. Codegen keeps it next to string and no-substitution template literals when annotation comments are enabled, and the property mangler reads that classification instead of scanning source text. Final output still follows the normal comment options, so whitespace-minified or annotation-disabled output removes the marker.
## Example
Input:
```js
const object = { _field: 1 };
const key = /* #__KEY__ */ "_field";
object[key];
```
Before, an intermediate codegen pass could remove the marker:
```js
const object = { _field: 1 };
const key = "_field";
object[key];
```
After, the marker survives for the later property-mangling pass.
Verified with the affected crate suites, `just minsize`, workspace lint, docs, AST generation, and independent review. `just ready` is only blocked locally by existing Node-version and terminal-color snapshot differences.
