fix(ci): give planning smoke enough time

[blove]

Summary

• give the shared LangGraph backend verifier a planning-specific stream timeout
• export the timeout policy so it can be covered without running the live verifier
• add cockpit unit coverage that keeps planning above the default smoke timeout

Root Cause

Production smoke was failing before Playwright ran. The Verify shared LangGraph backend step consistently reported the shared deployment as healthy and passed six assistant probes, but planning aborted exactly at the verifier's fixed 30s stream timeout. That graph intentionally does two model calls: one to create structured plan state, then one to execute the plan and answer.

Validation

• node ../../node_modules/vitest/vitest.mjs run src/lib/verify-shared-deployment.spec.ts --config vite.config.mts --reporter=verbose from apps/cockpit
• node node_modules/.bin/tsx scripts/verify-shared-deployment.ts --dry-run
• NX_DAEMON=false node node_modules/.bin/nx test cockpit --skip-nx-cache --runInBand
• git diff --check
