Subject: [PATCH] Enable DeepSeek cache warming + HTTP/2 compression (v0.9.1)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three improvements for DeepSeek API cost/performance:

1. Daemon cache warming: export DEEPSEEK_API_KEY, COLIBRI_CACHE_WARMING=true,
   COLIBRI_CACHE_WARMING_INTERVAL_HOURS=6 in rc.d prestart. Keeps DeepSeek
   prefix cache warm across sessions (~3,500 free tokens/request).

2. pi HTTP/2: change allowH2:false → true in http-dispatcher.js after
   npm install. Enables HPACK header compression and multiplexing for
   API calls (Node 24 + undici 8.3 handle this correctly).

3. Live verification: cache warming triggered and confirmed cache HIT
   with 3,584 hit tokens on first warm cycle.

Tested: daemon restart, cache warming log, CLI status confirms enabled.
