feat(eve): tag workflows with channel request ids

[ruiconti]

Inbound Vercel requests carry x-vercel-id, but we never wrote it to workflow rows. When a platform request opened a session or resumed a turn, there was no way to join that workflow run back to the request that caused it. This records the id as a workflow attribute.

What

• Read x-vercel-id off the inbound channel route and thread it through send, run, and deliver as requestId.
• Serialize it into workflow context as eve.channelRequestId.
• Emit $eve.channel_request_id on session, subagent, and turn rows.
• Missing header means no id. We don't invent one.

Route → runtime

channel-dispatch.ts reads the header once per request and builds a route agent that injects requestId into deliver/run. It spreads into a fresh input each call, so a frozen caller input is never mutated. createSendFn takes the id as a metadata.requestId argument.

Context

New ChannelRequestIdKey. buildRunContext sets it from RunInput.requestId, so run carries it into the serialized context the driver starts with. deliver puts it on the resume hook payload, so a resumed turn picks it up too.

Attributes

readChannelRequestId reads the slot and drops empty or non-string values. The session, subagent, and turn attribute builders emit $eve.channel_request_id from it — undefined when the run didn't start from an inbound route, like a schedule.

Doesn't touch

Driver hook timing, rekey, cross-channel receive, subagent callback routing. No behavior change beyond the new attribute.

Ported from ash#1004, with three changes for this repo

• The run test stubs VERCEL_ENV=production. Latest-deployment routing is gated on it here (shouldRouteToLatestDeployment), so without the stub the run pins to the current deployment and the deploymentId: "latest" assertion fails.
• Changeset is patch, not minor. The change only adds optional fields and new exports, so nothing breaks — a patch under the pre-1.0 rule.
• workflow-entry.ts was already sitting at the 700-line cap, so the two new requestId fields tip it over. The two deliver payloads stay inline (no extra consts) and the file gets a temporary allowlist entry with a TODO to extract the deliver-routing helpers (routeDeliverForChildren, waitForNextDeliver).
