jsii crashes with internal Error when using `effect/schema`

### Describe the bug

The following Code makes jsii crash:

```ts
import { Schema } from "effect"

export class BaseMessage extends Schema.Class("BaseMessage")({
op: Schema.String,
id: Schema.UUID,
data: Schema.Unknown
}) {}
```

`package.json`
```json

"description": "Library to validate the Ommited Messages",

"name": "Author",

},
"dependencies": {
"@effect/schema": "^0.75.5",
"effect": "^3.12.1"
},
"bundledDependencies": [

],
"stability": "experimental",

}
},
"outdir": "./lib",
"tsc": {
"outDir": "dist",
"rootDir": "src"
}
}
}
```

jsii Error:
```txt

```

This happens when running with node or bun. The above error is when running with node, despite the paths saying .bun

Running with bun produces the same error, just different wording:
```txt

### Regression Issue

- [ ] Select this option if this issue appears to be a regression.

### Expected Behavior

jsii compiles the code or gives an error why it can not be compiled

### Current Behavior

jsii encounters an internal error

### Reproduction Steps

Described above

### Possible Solution

Check why `base.symbol` is undefined in `jsii/lib/assembler.js:871`

### Additional Information/Context

```
jsii --version
5.7.4 (build fc2a28e), typescript 5.7.3
```

### SDK version used

5.7.4 (build fc2a28e), typescript 5.7.3

### Environment details (OS name and version, etc.)

Pop!_OS 22.04 LTS with kernel 6.9.3-76060903-generic

Reproduce the failure with the provided effect/schema example using jsii 5.7.4 and TypeScript 5.7.3. Start at jsii/lib/assembler.js:871 and inspect the path to _hasInternalJsDocTag at line 1866, focusing on why base.symbol is undefined. Done means jsii compiles the example or reports a specific supported error instead of JSII9997.
