1. Fixed crash in /api/cli-tools/status when statuses[toolId] is undefined
- Added null check before accessing statuses[toolId] properties
- Prevents "Cannot set property of undefined" error
2. Added support for droid.exe detection in ~/bin directory
- Added ~/bin and ~/.local/bin to EXPECTED_PARENT_PATHS
- Added droid.exe variant to toolBins for Windows
- Added specific path check for droid in ~/bin/droid.exe
These fixes resolve issues where CLI tools (Claude Code, Codex, Droid)
were showing as "not installed" even when properly installed.
