Pull request: [compiler]: fix link compiler & 4 broken tests from path containing spaces

## Summary

Problem #1: Running the `link-compiler.sh` bash script via `"prebuild"` script fails if a developer has cloned the `react` repo into a folder that contains _any_ spaces. 3 tests fail because of this.

<img width="1027" alt="fail-3" src="https://github.com/user-attachments/assets/1c4f4429-800c-4b44-b3da-a59ac85a16b9" />

For example, my current folder is:
`/Users/wes/Development/Open Source Contributions/react`

The link compiler error returns:
`./scripts/react-compiler/link-compiler.sh: line 15: cd: /Users/wes/Development/Open: No such file or directory`

Problem #2: 1 test in `ReactChildren-test.js` fails due the existing stack trace regex which should be lightly revised.

`([^(\[\n]+)[^\n]*/g` is more robust for stack traces: it captures the function/class name (with dots) and does not break on spaces in file paths.
`([\S]+)[^\n]*/g` is simpler but breaks if there are spaces and doesn't handle dotted names well.

Additionally, we trim the whitespace off the name to resolve extra spaces breaking this test as well:

```
-     in div (at **)
+     in div  (at **)
```

All of the above tests pass if I hyphenate my local folder:
`/Users/wes/Development/Open-Source-Contributions/react`

I selfishly want to keep spaces in my folder names. 🫣
