feat(webhook): add tunnel = "external" for externally-managed ingress#98

Conversation
Adds a webhook tunnel mode for when a tunnel already exists but is managed OUTSIDE ephemerd — e.g. a Cloudflare tunnel on another host forwarding a public hostname to ephemerd's webhook port. In this mode ephemerd serves the /webhook/<provider> receiver and disables polling, but does NOT create a tunnel or auto-register the GitHub webhook (that ingress and registration are owned externally). A matching secret is required so incoming signatures can be verified — unlike managed tunnels (ngrok/localtunnel) we must not invent one. Also fixes a misleading log line: with a webhook secret set but tunnel = "none", ephemerd already ran in webhook mode (polling disabled) yet logged "polling mode enabled (tunnel disabled)". The startup log now reflects the real discovery mode for each tunnel setting, and the webhook port defaults to 8080 whenever a receiver is active.

Fixes a misleading startup log: with a secret set but
tunnel = "none", ephemerd already ran webhook-only (polling disabled) yet loggedpolling mode enabled (tunnel disabled). The log now reflects the real discovery mode per setting, and the webhook port defaults to 8080 whenever a receiver is active.Tests: external-requires-secret, external keeps the provided secret + defaults port, managed tunnel still auto-generates, none+secret defaults port.
Note
No Cloudflare creation code is added —
externalis for an externally-run tunnel. A managedcloudflareprovider (shelling out tocloudflared) could be a follow-up if the host should self-serve the tunnel.🤖 Generated with Claude Code
