frugon v0.2.2

A dramatically faster analysis pass, a cleaner "Candidates considered" legend, and a fixed demo image on PyPI.

Fixed

Analysis is dramatically faster — two hot-loop costs fixed. First, pricing a large log was checking the pricing file on disk once per record — tens of thousands of redundant filesystem checks per run. It now checks once per run; this was the largest single cost, and it speeds up every analysis (single-model, --wholesale, and --candidates runs alike). Second, the "Candidates considered" block introduced in v0.2.1 was re-running the easy/hard call classification once per candidate — up to 23 times over the same call set — even though that classification never depends on the candidate; it now runs once and every candidate's projection is derived from it. Together, on the bundled ~56,100-call demo, the analysis pass dropped from roughly 17 seconds to about 1 second, and the pause after "Priced" is gone. The figures are unchanged to the cent.
The demo image now renders on PyPI. The README's demo GIF used a relative path that GitHub resolves but PyPI's project-page renderer does not, so the animated demo never showed up on pypi.org/project/frugon. It now points at the raw GitHub URL, so it renders on both.

A clearer "Candidates considered" legend on a default (no --candidates) run. The pool size and how many rows are shown now sit right in the header — "23 in pool · top 5 shown" — instead of a trailing sentence you'd read after the table. The two paragraphs of prose below the table are now three short bullet points: what each row represents, how the recommendation is picked, and how to compare specific models or measure quality yourself. An explicit --candidates run is unchanged.
