feat(eve): remote authorization events via the durable resumeHook path

[ruiconti]

Replaces the closed #1204. For #1170. Stacked on #1202 (terminal envelope).

What changed and why

#1204 relayed a remote callee's authorization.* through a best-effort route-direct side channel (world.streams.write, drop-ok). That was the wrong lane. Authorization events are low-frequency control — a handful per session, gated by human sign-ins — so they belong on the main run's durable path, exactly where a local subagent's authorization events already go.

This PR does that:

• The callee forwards each authorization.required/authorization.completed to the caller's session-callback URL as a status: "notification" event (session-callback-notification.ts).
• The caller's callback route projects it into a subagent-authorization-event hook payload and resumeHook(continuationToken)s the parked parent turn — the same durable resume the terminal callback uses.
• The turn workflow handles it identically to a local subagent's authorization event (turn-workflow.ts → runProxySubagentEventStep → re-emit on the parent stream). Zero new handling in workflowEntry; it reuses the local path.

So local and remote authorization now converge on one mechanism, and nothing rides a lossy side channel.

The lane split (see #1205)

The separate high-frequency progress lane — the one that must stay off the main run's replay journal — remains reserved. It has no concrete event type yet, so it's future work; "working"/"input_required" stay reserved on the wire.

Not yet here

• e2e verification. The fixture + evals aren't ported onto this branch yet. This branch re-emits authorization events raw on the parent stream (the durable proxy path), so the evals need feat(eve): propagate remote-callee authorization events to the caller #1167's top-level authorization.* assertions with the interactive-connection fixture (since the eve/tools export is dropped) — an adaptation, not a copy. Tracked as the next step; unit coverage (route projection + callee forwarder, 24 tests) is green in the meantime.
• Remote input.required (proxied HITL) — shelved follow-up.

Unit suite 5367 green, lint + guard clean.

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: 2.71 s -> 2.68 s (-35.5 ms) vs rui/remote-terminal-callback (8be5119).
• Timing is informational: shared GitHub runners are too variable for a hard timing budget.
