When installing the Gateway daemon via LaunchAgent (macOS) or systemd (Linux),
environment variables defined in config.env.vars were not being included in
the service environment. This caused API keys and other env vars configured
in clawdbot.json5 to be unavailable when the Gateway ran as a service.
The fix adds a configEnvVars parameter to buildGatewayInstallPlan() which
merges config.env.vars into the service environment. Service-specific
variables (CLAWDBOT_*, HOME, PATH) take precedence over config env vars.
Fixes the issue where users had to manually edit the LaunchAgent plist
to add environment variables like GOOGLE_API_KEY.
This PR includes three main improvements:
1. Tailscale Binary Detection with Fallback Strategies
- Added findTailscaleBinary() with multi-strategy detection:
* PATH lookup via 'which' command
* Known macOS app path (/Applications/Tailscale.app/Contents/MacOS/Tailscale)
* find /Applications for Tailscale.app
* locate database lookup
- Added getTailscaleBinary() with caching
- Updated all Tailscale operations to use detected binary
- Added TUI warning when Tailscale binary not found for serve/funnel modes
2. Custom Gateway IP Binding with Fallback
- New bind mode "custom" allowing user-specified IP with fallback to 0.0.0.0
- Removed "tailnet" mode (folded into "auto")
- All modes now support graceful fallback: custom (if fail → 0.0.0.0), loopback (127.0.0.1 → 0.0.0.0), auto (tailnet → 0.0.0.0), lan (0.0.0.0)
- Added customBindHost config option for custom bind mode
- Added canBindTo() helper to test IP availability before binding
- Updated configure and onboarding wizards with new bind mode options
3. Health Probe Password Auth Fix
- Gateway probe now tries both new and old passwords
- Fixes issue where password change fails health check if gateway hasn't restarted yet
- Uses nextConfig password first, falls back to baseConfig password if needed
