feat(scanner): force rescan = original scan; feat(filters): the manually-edited filter (faceted plan Phase 13)

Force rescan contract change (owner-directed): the editorial-keep skip
is retired. Force rescan now re-derives EVERY field on EVERY book from
all sources — multi-file books included (the folder/zip flows ran the
full chain on create and on manifest-flagged edits, but skipped the
sidecar apply under force). metadata_overrides is the only protection:
ApplyMetadataOverrides re-applies manual values inside the writer, so
manual edits survive; everything else re-derives.

- A force pass also STAMPS each re-derived book's manifest with the
  current parser version (success-only — same truthfulness rule as
  Phase 10) and closes its open processing issues (Phase 11 self-heal).
  Force rescan and the ev-bump trickle now converge: either leaves the
  library fully current; the deploy order is bump-first, then Rescan
  All (documented in the plan and contract_pins).
- Single-file force rescan already ran the full chain — unchanged,
  now pinned.

NEW filter field manually_edited ("Manually edited", boolean):
cardinality(mi.metadata_overrides) > 0 / = 0. Composed-engine (qf)
only — the builder's Book facts group gains it with is true/false;
no value menu, no suggestion surface; family lens inherited.

Tests: multifile force applies sidecar metadata + stamps + override
protection; single-file pin; the filter both directions scoped to the
test library; adjacent suites (Audiobook, Calibre, ExtractorVersion,
CrossLibraryMove, ProcessingIssues, FilterBuilder, SchemaIdempotency)
green. The extractor mechanism itself is untouched — the owner bumps
scan_extractor_version manually via the admin UI (plan Phase 13 §3).
