feat(eve): add first-class Photon channel

[OwenKephart]

Summary

• Add photonChannel() as a first-class eve channel for Photon-powered iMessage.
• Accept lazy credentials from connectPhotonCredentials(), use Photon signing secrets when configured and same-project Vercel OIDC otherwise, and route new/subscribed threads into eve sessions.
• Mark accepted messages as read by default without failing delivery when the receipt fails.
• Vendor the Photon adapter into eve and document the public API.

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

export default photonChannel({
  credentials: connectPhotonCredentials(process.env.PHOTON_CONNECTOR_ID!),
});

Validation

• Covered lazy credential construction and default/custom webhook routing.
• Verified public package types, the compiled vendored adapter, and focused channel tests.

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: 1.89 s -> 1.90 s (+12.0 ms) vs main (6dc662c).
• 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).
