Subject: [PATCH] doorbell-listener: poll every 5s (was 30s) for tighter lag
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ntfy /json?poll=1 is regular polling, not long-poll. Worst-case
lag = 2 × POLL_INTERVAL × N_topics = 120s at 30s. Reducing to 5s
caps lag at ~20s with 2 topics. For sub-second latency, switch to
ntfy SSE (/<topic>/sse) - tracked separately.
