[BUG]: Generating from a folder of schema files gives invalid results

Generating using the following syntax to pick up all of the json schemas in a folder produces a generated file where the results are incorrect.

## Issue Type

parsing (I think)

## Context (Environment, Version, Language)

Input Format: Schema
Output Language: Verified with C#, Java, and Rust

CLI, 23.0.170

## Description

I have two schema files "Person" and "Product" that both reference a third file "Location".

If I generate specifying each of those files separately then I get something sensible (although see also [this bug](https://github.com/glideapps/quicktype/issues/2633)).

If I generate using the folder with them in it as an input then the results make no sense, missing properties, adding in the schema, ID, title, and description.

## Input Data

[BugReportGenerateFromFolder.zip](https://github.com/user-attachments/files/16281634/BugReportGenerateFromFolder.zip)

See the readme in this zip.

The results were generated with
`quicktype --lang rust --src-lang schema --out generatedFromFiles.rs --src .\product.json --src .\person.json --src .\location.json`
and
`quicktype --lang rust --src-lang schema --out generatedFromFolder.rs --src .\`
(I've tried giving the absolute path rather than a relative one - no change)

## Expected Behaviour / Output

The results from generating a folder with json schemas in it should be identical to specifying each of those schemas separately.

## Steps to Reproduce
Unzip the example files.
Run the two commands.
Do a file compare on the two generated files.
