v0.97.0 — the run becomes evidence

The run becomes evidence. Every journal line carries a hash chain — nika trace verify walks it and names the first broken link; export and replay check the chain before trusting the data. nika trace reproduce compares a recorded run against a fresh one and classifies every task (reproduced · nondeterministic · authored · environment). The journal attests its engine (engine_version + platform on workflow_started). Models are priced before the first run — 602 rules refreshed from models.dev, per-model rates in check --json (the VS Code preflight shows $in/$out per 1M on this tag). check IS the dry-run — the plan names what dispatches in which wave. doctor --json speaks machine; bare nika init/new converse on a terminal.
