feat(eve): add first-class Photon iMessage channel

[OwenKephart]

Summary

Add photonIMessageChannel() as a first-class eve channel for Photon-powered iMessage. It gives authors a focused iMessage API while leaving room for Photon integrations on other messaging platforms to have their own explicit surfaces.

import { connectPhotonCredentials } from "@vercel/connect/eve";
import { photonIMessageChannel } from "eve/channels/photon";

export default photonIMessageChannel({
  credentials: connectPhotonCredentials("photon/my-agent"),
});

• lazy Photon credentials, including Vercel Connect support
• same-project Vercel OIDC verification for Connect-forwarded webhooks, or Photon signing-secret verification for direct webhooks
• first inbound iMessage mentions subscribe the thread, including blank/attachment-only messages, so follow-up messages are delivered
• queue overlapping inbound messages and skip events with no model-visible content
• mark accepted inbound messages read without letting receipt failures block delivery

The Photon adapter is vendored into eve and the public API is documented.

Validation

pnpm --filter eve build:compiled
pnpm --filter eve exec vitest run --config vitest.unit.config.ts \
  src/public/channels/photon/photonIMessageChannel.test.ts \
  src/public/channels/photon/inboundContent.test.ts

Build Timing: e2e/fixtures/agent-tools-sandbox

This is an informational timing measurement inside eve build, from preflight through publication. Output-size measurement and profile writing are excluded.

Build mode: deployable Vercel build with sandbox template prewarm included.

• Build pipeline: 2.01 s -> 1.99 s (-26.1 ms) vs main (0c0de19).
• Timing is informational: shared GitHub runners are too variable for a hard timing budget.

Additional Suggestion:

validate-channel-registry.ts checks a non-existent meta.eve.channel field, so it always throws on the first delegating channel item and breaks the docs build (registry:check).
