fix: resolve claude binary path for daemon-spawned agent

Browse Source 
The browse server runs as a daemon and may not inherit the user's shell
PATH. Add findClaudeBin() that checks ~/.local/bin/claude (standard
install location), which claude, and common system paths. Shows a clear
error in the sidebar chat if claude CLI is not found.
