Add diagnostic script and improve permission fix for talkkonnect
Added diagnose_talkkonnect.sh to help troubleshoot installation issues: - Checks binary installation - Finds all config files and shows ownership - Analyzes systemd service configuration - Detects audio/PipeWire sessions for each user - Identifies permission mismatches - Provides specific recommendations Improved fix_talkkonnect_permissions.sh: - Now automatically updates systemd service file if needed - Changes service user to match target user - Updates config path in service file - Reloads systemd after changes - Stops service before making changes These tools help resolve the "permission denied" error when talkkonnect is configured to run as one user but config is owned by another.
