Adds a per-(provider, model) audit table showing the raw token fields each
provider records (input, output, reasoning, cache write/read) alongside the
totals codeburn displays and prices. It makes the normalizations explicit:
reasoning folds into output, the Anthropic cacheReadInput / OpenAI cached
vocabularies collapse to a per-call max, and cache write/read use the 1.25x /
0.1x input multipliers when a model omits explicit cache rates.
--format json adds per-component cost, the applied rates, both raw cache-read
fields, and recomputed vs attributed cost, so any token-to-cost drift is
visible in one command. Same options as `codeburn models`.
