fs_read tool fails to handle symlinks properly in WSL

Expected Behavior:
fs_read should be able to read directories through symlinks. When given a path like /home/USER/.aws that is a symlink to /mnt/c/Users/USER/.aws, it should follow the symlink and read the target directory.

Actual Behavior:
fs_read fails with error "Path is not a directory: ../../mnt/c/Users/USER/.aws" when trying to read a symlinked directory. The tool appears to be generating an invalid relative path instead of properly
resolving the symlink.

Steps to Reproduce:
1. In WSL environment, create a symlink: ln -s /mnt/c/Users/USER/.aws /home/USER/.aws
2. Try to read the symlinked directory with fs_read: {"mode": "Directory", "path": "/home/USER/.aws"}
3. Tool fails with symlink resolution error

Environment:
• OS: Linux 5.15.167.4-microsoft-standard-WSL2 - Ubuntu 24.04.3 LTS
• Q CLI version: 1.15.0
• In WSL: true
