Bump BRAIN_TESTS_FLOOR to 82 (SB-S2 adds consolidate(12)+consolidate-cli(7)).
No new test-runner section → ASSERT_BASELINE_FLOOR unchanged at 78 (the hook
SC6 test runs separately via `node --test hooks/scripts/__tests__/*.test.mjs`,
not the structure gate). Add docs/second-brain/consolidation-loop.md (CLI usage,
engine rules, the candidate-file session↔engine contract, operator gate, honest
limits incl. no-reader-until-S3). Gate 93/0/0; hook suite 136/0.
