Webhook agent runs default to the constrained hermes-webhook toolset
(web/vision/clarify) because payloads can carry untrusted third-party
content. That default is right for public webhooks but wrong for trusted
local pushes (e.g. an OOM monitor daemon that needs the agent to run
ps/free/py-spy): the only workaround was widening platform_toolsets.webhook,
which elevates EVERY webhook route at once.
This adds a 'toolsets' key on individual webhook route configs (static
routes in config.yaml and dynamic subscriptions in
webhook_subscriptions.json) that replaces the platform-level resolution
for that route only:
- BasePlatformAdapter.toolsets_for_source(): per-source override hook,
default None (no behavior change for any other platform).
- WebhookAdapter.toolsets_for_source(): maps the session chat_id
(webhook:{route}:{delivery_id}) back to its route config and returns
the route's toolsets list.
- GatewayRunner._resolve_enabled_toolsets_for_source(): shared resolver
used by both agent-run call sites; validates the override through the
SAME _get_platform_tools path as platform config, so unknown names and
platform-restricted toolsets (e.g. discord_admin) are dropped rather
than trusted.
Deliberately NOT exposed via 'hermes webhook subscribe': granting elevated
tools is a manual config edit only, so an agent-created subscription
cannot self-grant terminal at runtime.
Cache-safe: the toolset list is resolved before agent construction and is
constant for a route, so the per-session agent signature and frozen system
prompt are unaffected mid-conversation.
