IB-WP-0016-T07: review report and output policy; close IB-WP-0016

Enrich reports/generation-summary.md with the review-oriented sections
that the 2026-05-17 smoke run flagged as missing: ## Chapter coverage
(per-chapter source/entity/relation/anchor counts), ## Entities (the
deduped title list), ## Unmapped source chunks (sources with no
downstream generated artifact), and ## Page anchors (total plus
deterministic sample). Sections are conditional on data being present
so generic non-Lefevre runs stay terse.

Add docs/lefevre-readiness.md as the final sign-off document for
IB-WP-0016: what is wired (T01-T06 recap), an output policy table
(checked-in fixture sources vs disposable generated infospaces vs
archive targets), a seven-item reviewer checklist (duplicate entities,
relation endpoints, weak evidence, overgeneralization, anchor
coverage, unmapped sources, plan-vs-actual variance), a scale-up plan
from one-chapter to full-book, and the load-bearing risks still
outstanding (cross-chunk dedup, whole-run resume, adaptive routing
deferred to LLM-WP-0004 / IB-WP-0018, rate-table drift).

Closes IB-WP-0016 (Lefevre EPUB3 Infospace Readiness Pilot): T01-T07
all done; the workplan is set to status=done.

131 tests pass, 1 skipped (live OpenRouter smoke, correctly gated).
