- extract the headless search out of `easy` into an engine that
measures the baseline, resolves the target, and drives the
producer/consumer loop, so the CLI and web share one search
- make `State` fully observable — structured discovery feed, run phase,
baseline/target, and final outcome — and render the same snapshots two
ways: the in-place terminal panel and an SSE stream
- serve a small embedded page (HTML/JS/Pico baked in via include_str!)
on a hand-rolled hyper service: POST /api/run runs one search at a
time, GET /api/events streams live snapshots as JSON until it settles
- open the UI on a bare invocation (double-clicked binary); `web` with
--host/--port/--no-open controls it explicitly
- bump to 0.2.0
