Campaign B: binary size

Metric: sum of bytes of worker, mcp and 6 hook binaries (release flags, -s -w -trimpath, -tags fts5). Lower is better. Threshold: at least 3% drop, tests green. Stop: 5 consecutive no-improve trials or 15 trials. Mutate: Go code and build flags. Frozen: public API, DB schema, plugin manifest.

id	mutation	total bytes	delta vs base	kept?
01	baseline	102698416	-	base
02	pkg/hooks: raw HTTP/1.0 client replaces net/http	87603952	-14.7%	KEEP
03	statusline: shared client, drop net/http	84531056	-3.5% vs 02	KEEP
04	embed gzipped ONNX runtime libs, gunzip at first use	57216880	-32.3% vs 03	KEEP

Notes:

• Trial 04 needs scripts/download-onnx-libs.sh to produce .gz files; existing raw libs trigger a re-download.
• Extracted library verified byte-identical to the raw dylib (cmp).
