Bug Description

On a newly created typescript project with almost no source code, claude repeatedly trips over the edit of src/main.ts until it finally crashes with the following exception:

node:internal/process/promises:394
    triggerUncaughtException(err, true /* fromPromise */);
    ^

Error: String not found in file. Failed to apply edit.

The interesting thing is the path that Claude wants to use to update the file. It tries to update a file with this path:

⏺ Update(../../../christian/hujer/WebstormProjects/NewProject_TypeScript_withPlayground/src/main.ts)
  ⎿  Error: File does not exist.

The correct path would have been ../../../christian.hujer/WebstormProjects/NewProject_TypeScript_withPlayground/src/main.ts

It appears that a period in the system user name (christian.hujer) trips over the current version of Claude code in certain situations.

Steps to Reproduce

1. Create a user with a period in their name.
2. Create a new TypeScript project without tests
3. Start claude
4. Ask Claude to create the tests for you

Expected Behavior

Claude creates the tests.

Actual Behavior

Claude crashes with the following error message and stack trace:

node:internal/process/promises:394
    triggerUncaughtException(err, true /* fromPromise */);
    ^

Error: String not found in file. Failed to apply edit.
