What’s new

• scripts/embedded/test-cron-event-driven.ts - Operational test verifying cron timer precision

Performance

• Event-driven cron scheduler - Replaced 1s setInterval polling with precise setTimeout that wakes exactly when the next cron is due. Zero wasted ticks between executions:

  Scenario	Before	After
  1 cron every 5min	300 ticks/5min (299 wasted)	1 tick/5min
  0 crons registered	1 tick/sec (all wasted)	0 ticks
  Cron in 3 hours	10,800 wasted ticks	1 tick at exact time

• A 60s setInterval safety fallback catches edge cases (timer drift, missed events). Zero functional changes, zero API changes.
