Felix Connector v0.4.3

• Fix: Connected status is keyed off poll-loop heartbeat, not skipped last_run_at (a skipped cron tick no longer looks Connected)
• Fix: disconnecting clears the runner lease so a re-pair within ~60s can check in immediately
• Fix: list_orders + search_orders use real WooCommerce queries (billing_email on HPOS and classic orders)
• Fix: invalid money/qty refused as validation_error before WooCommerce is mutated; handlers catch Throwable
• Fix: missing FELIX_API_BASE fails closed (no silent production pairing from local/staging)
• Docs: production requires a 1-minute host poll; 5-minute host cron is unsafe vs 120s command TTL
