[BUG] Title: Bash tool: third-party CLI binaries silently fail (exit 1, no output) even with dangerouslyDisableSandbox: true

What's Wrong?
When Claude Code's Bash tool executes certain third-party CLI binaries, they fail silently with exit code 1 and no output — even when dangerouslyDisableSandbox: true is set. The same binaries work perfectly in the user's terminal.
Environment:
- OS: Fedora Linux 6.19.8-200.fc43.x86_64
- Shell: bash
- Claude Code version: (doplň claude --version)
- Affected binary: glab 1.89.0 (/usr/bin/glab)
Steps to reproduce:
- Install glab (GitLab CLI) — e.g. sudo dnf install glab
- Verify it works: glab --version → prints glab 1.89.0 ()
- Ask Claude Code to run: glab --version
- Bash tool returns exit code 1, empty output
Expected behavior:
glab --version executes and returns glab 1.89.0 () — same as in the terminal.
Actual behavior:
Exit code 1
(no output, no stderr)
Additional notes:
- git (same permissions, same location /usr/bin/) works correctly via Bash tool
- ldd /usr/bin/glab shows no missing libraries
- Adding Bash(glab:*) to permissions.allow in settings.json did not help
- Using dangerouslyDisableSandbox: true in the tool call did not help
- The issue appears to affect other third-party binaries as well (not just glab)
Thank you

What Should Happen?
All commands which are working in bash (have correct PATH etc) should work in claude-code.
