feat(web): create webhook automations and inspect their deliveries

[juliusmarminge]

Web users had no way to create webhook tasks or see what a webhook sent.

The scheduled-task editor gets an On webhook option with:

• the URL (the T3 Connect URL, or this environment's address), with Copy and Rotate (rotate asks first);
• a hint listing the placeholders;
• an optional Require signature section with header, prefix and encoding, defaulting to GitHub's settings, plus a write-only secret.

In the task list, webhook tasks read "On webhook · Listening". Their menu has Deliveries instead of Run now. Deliveries lists recent requests with their outcome, and opening one shows the prompt sent to the agent next to the request's headers and body.

docs/user/project-settings.md gains a short "Webhook automations" section.

Before / after

Before (main)	After

The URL field is blurred because it holds a private tailnet address.

Verification

• Exercised in the Browser panel against a dev server seeded with a copy of real data and the signed curl requests described in the server PR.
• Web typecheck and lint are clean.
• scheduledTasksSettings.logic.test.ts (22 tests) passes, including the webhook draft and schedule mapping, the blank secret keeping the stored one, and the URL resolution.

📝 Walkthrough

Walkthrough

Scheduled-task settings now support webhook schedules, signature configuration, endpoint controls, and delivery inspection. Runtime state exposes query atoms for delivery lists and details. Project settings documentation describes webhook behavior.

Changes

Webhook scheduled tasks

Layer / File(s)	Summary
Webhook schedule and draft model apps/web/src/components/settings/scheduledTasksSettings.logic.ts, apps/web/src/components/settings/scheduledTasksSettings.logic.test.ts, apps/web/src/components/settings/ScheduledTasksSettings.tsx	Draft conversion supports webhook schedules and signature settings. Tests cover schedule conversion and endpoint URL selection.
Webhook editor and endpoint controls apps/web/src/components/settings/ScheduledTasksSettings.tsx	The editor adds webhook prompt and signature controls, endpoint URL display, copying and rotation, and validation for required signature settings. Linked webhook tasks can now open in the editor.
Task delivery inspection apps/web/src/components/settings/ScheduledTasksSettings.tsx, packages/client-runtime/src/state/server.ts, docs/user/project-settings.md	Webhook task rows offer delivery history. The dialog displays delivery details, runtime state exposes delivery query atom families, and documentation describes webhook settings and delivery behavior.

Explanation

The description explains the problem, changes, and verification, and includes before-and-after screenshots. It does not include the required Scope and approval information or a link to a triaged issue or approved discussion. This feature adds a new workflow, so the template’s small-fix exception does not appear to apply.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR adds a complete webhook automation workflow, including externally triggered agent runs, URL rotation, signature settings, and delivery logs containing request data. It also introduces default prompt and GitHub signature behavior, making the runtime and product-default impact too broad for automatic approval.

No code changes detected at b591463. Prior analysis still applies.
