docs(learning-harness): implementation plan, 28 tasks in 5 groups, two sanity reviews

Foundation: taxonomy, DeepSeek endpoint, corpus fields, TypeScript grammar,
curated hunter tools. Core: classifier tiers and measurement, per-pair family
scoring and aggregation, detector configurations and runner, verifier registry
with oracle callback, canary templates and second judge, journal and archive.
Integration: one teacher rule, family scoring on the pairs hunter path, round
zero with per-model noise floors, scan-path tags and manifest block, proposers,
acceptance and revert, round orchestration, publish, subcommands. Corpus
repairs and validation last. Both sanity reviews' findings recorded in the
plan; K-run evaluation honors requirement 3.5 at every stage.
