feat(runtime): emit sandbox run hook events

[drewstone]

Summary

• add passive hooks, runId, scenarioId, and deterministic now support to openSandboxRun
• emit factual agent.run / agent.turn lifecycle events with prompt hashes, event counts, session/box ids, deliverable metadata, and error/read status
• record runtime hook events into benchmark corpus rows via a bench-local structural recorder, without importing agent-eval or adding runtime analysis claims
• cover lifecycle emission and hook-error isolation in sandbox-run tests

Verification

• pnpm typecheck
• pnpm lint (passes; existing tests/profiles/coder.test.ts template-literal warnings remain)
• pnpm exec vitest run tests/runtime/sandbox-run.test.ts
• pnpm typecheck:examples
• pnpm test
• pnpm build
• pnpm verify:package
