feat: add extrabiblical meta table + validator (#1538)

[CraigBuckmaster]

What this does

Introduces the extrabiblical meta table — first-class schema for Second Temple and apocryphal literature (1 Enoch, Jubilees, Jasher, Apocrypha, DSS). Seeds content/meta/extrabiblical.json as an empty array; content follows in HWGTB-P1-04 (#1541).

Closes

Closes#1538

Changes

• New filecontent/meta/extrabiblical.json — empty array.
• _tools/build_sqlite_schema.py — CREATE TABLE extrabiblical with all 17 columns from the issue's schema plus idx_extrabiblical_category index.
• _tools/build_sqlite_loaders.py — populate_extrabiblical() loader. Empty file → 0 rows.
• _tools/build_sqlite.py — loader imported and registered in the pipeline after populate_difficult_passages.
• _tools/schema_validator.py — new EXTRABIBLICAL section with all integrity checks from the issue: id shape/uniqueness, required top-level keys, category enum, tradition_status four-key check, brief/full summary shape, nt_citations[].ref regex, citation_refs[].type enum, cross-links against scholars.json, debate-topics.json, difficult-passages.json, and journey files.
• _tools/validate_sqlite.py — DB-side integrity: table exists, tradition_status_json / brief_summary non-empty, cross-link columns resolve to debate_topics, difficult_passages, and scholars row IDs.
• app/assets/db-manifest.json — content hash bump.

How I verified

Three-phase smoke test:

1. Temporarily populated extrabiblical.json with a valid dummy entry and confirmed all checks pass.
2. Switched the dummy's scholar_id to nickelsburg (not on master) — validator correctly reported 'nickelsburg' not in scholars.json. Tried ref: "Jude 14-15" — initial regex rejected it; fixed regex to handle multi-word book names and chapter-less references like Jude.
3. Reverted to empty array (final committed state) and confirmed:
   • python _tools/schema_validator.py — 136483 passed, 77 failed (same pre-existing set as master), 0 new failures ✅
   • python _tools/build_sqlite.py — extrabiblical: 0 rows ✅
   • python _tools/validate_sqlite.py — 94 passed, 0 failed, 2 warnings ✅

Out of scope

• Depends on [HWGTB-P0-01] Expand scholar registry: patristic + canon-formation voices #1537 (scholars.json additions). Works correctly off master because with an empty seed file no scholar-ID cross-checks fire. Once [HWGTB-P0-01] Expand scholar registry: patristic + canon-formation voices #1537 merges, HWGTB-P1-04 can reference nickelsburg/vanderkam freely.
• App-side rendering of extrabiblical detail screens — handled in HWGTB-P2-02 / P2-03.
• app/assets/explore-images.json drift reverted (unrelated to this issue).

Rollback

Revert this PR. The extrabiblical table gets dropped on the next build_sqlite.py run (table is (re)created from schema each build). No user.db migrations.
