Add stale eve client stream repro

[ruiconti]

Summary

• Add an agent-idle-stream-repro fixture app with an idle_stream_repro tool that waits before returning a deterministic marker
• Add a matching scenario descriptor for packaged eve dev coverage
• Add a dev-server scenario that stalls the first live stream after actions.requested, reads the durable tail from startIndex, and proves the client result remains pending

Notes

Repro only. This does not change client reconnect behavior or NDJSON stream handling.

Verification

• pnpm --filter agent-idle-stream-repro typecheck
• pnpm --filter agent-idle-stream-repro build
• pnpm --filter eve typecheck
• pnpm lint
• pnpm --filter eve exec vitest run --config vitest.scenario.config.ts test/scenarios/dev-server.scenario.test.ts -t "reproduces a live stream"

AI assistance

• e0 generated the fixture and scenario from the requested behavior and ran the verification above.
