v0.7.0 — measured token savings

What's new

• eval_repo.sh — lints a map, then probes every namespace with its own name as the grep pattern. Zero per-repo config; prints a per-row hit/byte table and mean pct_saved.
• check_namespaces.sh — map lint: dead scopes, duplicate tags, draft rows, generated dirs, coverage gaps.
• eval_scope.sh — single-query token delta: root grep vs scoped grep.
• Scaffold derives prefixes from the codebase's own vocabulary, nests sub-team rows (payments:checkout:), emits repo: slugs, and lands zero-TODO drafts.
