Summary:
- audit Doctor lint default selection after the full lint-family backfill
- make legacy state, skills readiness, session transcripts, and session snapshots explicit-only for default lint
- document default lint vs --all/--only and keep plugin/SDK public contracts unchanged
Validation:
- Galin review: no blocking findings
- maintainer accepted the default-lint compatibility tradeoff in PR comment
- exact-head hosted gates passed for d5d88a0db1: CI#28976811444 and Workflow Sanity#28976811343
- local broad pnpm check was blocked by a shrinkwrap guard failure that reproduces on origin/main and is unrelated to this five-file Doctor diff
