* Add generic host-verified webhook ingress for tools
* Stabilize trace E2E test rig and approval behavior
* Fix webhook security issues from review feedback
- Reject tools without webhook_capability() (was unauthenticated RCE)
- Remove secret-in-query-string fallback (leak via logs/referrers)
- Require approval for event_emit tool (escalation via routine triggers)
- Simplify header_value() (HeaderMap already case-insensitive)
- Redact internal errors from webhook HTTP responses
- Remove unused hmac_timestamp_tolerance_secs field
- Add regression test for tool without webhook capability

* Harden webhook ingress: require auth mechanism, body limit layer, health check
- Reject webhook capabilities that declare no auth mechanism (empty
WebhookCapability would previously allow unauthenticated access)
- Add DefaultBodyLimit layer to reject oversized payloads before buffering
- Health check (GET) now verifies tool has webhook_capability(), not just
existence
- Add regression tests for all three fixes

* Fix auto_approve_tools inconsistency between dispatcher and thread_ops
dispatcher.rs skips all approval checks (including Always) when
auto_approve_tools is true, but thread_ops.rs still required approval
for Always tools. This caused deferred tool calls to unexpectedly halt
in test rigs and auto-approve configurations.
Match dispatcher behavior: short-circuit all approval when
auto_approve_tools is enabled.
