Bug: rg.exe hangs when running from home directory (Windows) - scans millions of files

Description

When running opencode from the home directory on Windows, rg.exe scans ALL files in the home directory (including AppData, node_modules, go/pkg, etc.), consuming 95%+ CPU and 1GB+ RAM, making the system completely unresponsive.

This started after v1.17.2 when the default changed to use ripgreplayer on Windows instead of fff.

Steps to Reproduce

1. Open PowerShell on Windows
2. Run opencode from home directory (C:\Users<username>)
3. rg.exe starts scanning millions of files
4. System becomes unresponsive

Expected Behavior

opencode should skip heavy directories (AppData, node_modules, go, .cache, etc.) by default, or limit scan depth when not in a git repository.

Actual Behavior

rg.exe runs --no-config --files --glob=!.git/* which scans EVERYTHING.

Environment

• OS: Windows 11
• opencode version: v1.18.15
• rg version: 14.1.1
