test(pdf): integration smoke (w/ search + cancel) + vector regression + alnum e2e (#[ignore]) for v0.20 sub-item 1

Step 9 (Group I) of v0.20.0 sub-item 1 (scanned PDF OCR) plan.

I3 — crates/kebab-app/tests/ingest_pdf_ocr_smoke.rs (신규):
- ingest_with_mock_ocr_yields_pdf_ocr_summary — `#[ignore]` real Ollama,
  ingest_with_config production path + IngestItem.pdf_ocr_pages verify.
- ocr_text_indexed_and_searchable — `#[ignore]` real Ollama, app.search
  의 OCR text indexed verify (§ Acceptance #2).
- ingest_with_cancel_aborts_mid_pdf — production cancel chain (pre-set
  cancel=true + dummy endpoint, no panic/deadlock verify).

I4 — crates/kebab-parse-pdf/tests/text_extractor_regression.rs (신규):
- vector_pdf_extract_byte_identical_to_baseline — F4 mojibake.pdf 의 vector
  PDF path canonical 의 byte-identical 보존 (Step 1-8 모든 변경 전후 invariant).
- baseline 신규 = tests/snapshots/vector_pdf_canonical.json (first run create).
- normalize_provenance_timestamps inline helper (R-3 mitigation, workspace
  전체 부재 — 신규 12-line).

I5 — crates/kebab-parse-pdf/tests/ocr_e2e.rs (신규):
- f1_alnum_accuracy_ge_85 / f2_alnum_accuracy_ge_70 — `#[ignore]` real
  Ollama qwen2.5vl:3b, § Acceptance §9 #3 의 implementation.
- alnum metric = strsim::levenshtein (dev-dep 추가).
- truth file copy from PoC scratch (page1.txt + page2-batchim.txt) →
  scanned_page1_truth.txt + scanned_page2_truth.txt.
- kebab-parse-image dev-dep 추가 (OllamaVisionOcr::from_parts 호출용).
  parser isolation invariant 의 dev-dep exception (spec §3.1, dep graph
  baseline -e normal 보존).
