eve@0.30.7

Patch Changes

• e5c9191: Add experimental agent messaging behind experimental.subagentPersistentSessions in agent.ts. Opted-in agents keep delegated children alive after they answer: each child is owned by a lifecycle handle, settles every turn with an explicit outcome carrying its per-turn token usage, and parks instead of terminating. The parent's subagent tools gain an agentId parameter to continue a parked child, discoverable from a per-model-call <agents> system injection that lists only parked (resumable) children. An omitted, empty, or unknown agentId starts a fresh child; continuing a child that is still starting or working fails with AGENT_BUSY. Without the opt-in, children keep running as one-shot tasks. The subagent tool input schema no longer includes the unused description field.
• bd21332: Cancelling a turn with running delegated children no longer leaks their handles as permanently running. The cancellation epilogue now parks each abandoned child as "(cancelled)", so cancelled children stay resumable and later cancellations no longer stall retrying already-dead children.
• 1758161: Add guided GitHub channel setup through eve add channel/github. The flow provisions a Vercel Connect GitHub App, routes verified webhooks, scaffolds the channel, and explains how to install and use the app.
• 56de47b: Show far more of what local traces record in eve traces: span rows carry inline token/cost/tool chips, the header aggregates models, token totals, cost, and errors, and two new flags expose everything else — --verbose expands every span with all attributes and events, and --json dumps the full trace machine-readably.
