feat(webhook): direct delivery mode for zero-LLM push notifications (#12473)
External services can now push plain-text notifications to a user's chat
via the webhook adapter without invoking the agent. Set deliver_only=true
on a route and the rendered prompt template becomes the literal message
body — dispatched directly to the configured target (Telegram, Discord,
Slack, GitHub PR comment, etc.).

Reuses all existing webhook infrastructure: HMAC-SHA256 signature
validation, per-route rate limiting, idempotency cache, body-size limits,
template rendering with dot-notation, home-channel fallback. No new HTTP
server, no new auth scheme, no new port.

Use cases: Supabase/Firebase webhooks → user notifications, monitoring
alert forwarding, inter-agent pings, background job completion alerts.

Changes:
- gateway/platforms/webhook.py: new _direct_deliver() helper + early
  dispatch branch in _handle_webhook when deliver_only=true. Startup
  validation rejects deliver_only with deliver=log.
- hermes_cli/main.py + hermes_cli/webhook.go: --deliver-only flag on
  subscribe; list/show output marks direct-delivery routes.
- website/docs/user-guide/messaging/webhooks.md: new Direct Delivery
  Mode section with config example, CLI example, response codes.
- skills/devops/webhook-subscriptions/SKILL.md: document --deliver-only
  with use cases (bumped to v1.1.0).
- tests/gateway/test_webhook_deliver_only.py: 14 new tests covering
  agent bypass, template rendering, status codes, HMAC still enforced,
  idempotency still applies, rate limit still applies, startup
  validation, and direct-deliver dispatch.

Validation: 78 webhook tests pass (64 existing + 14 new). E2E verified
with real aiohttp server + real urllib POST — agent not invoked, target
adapter.send() called with rendered template, duplicate delivery_id
suppressed.

Closes the gap identified in PR #12117 (thanks to @H1an1 / Antenna team)
without adding a second HTTP ingress server.
