* feat: TSR-aware table extraction (extract_tables_with_structure_mem)
New public function that consumes raw structure-recovery output (HTML
structure tokens + per-cell bboxes from a model like SLANet) and assembles
markdown tables by pulling cell text from the native PDF — no OCR, no
geometry inference.
Why: the existing extract_tables_in_regions_mem infers grid geometry from
text positions only and can't distinguish merged cells from multiple narrow
columns. Pairing structure recovery from a layout/TSR model with native
PDF text gets perfect text quality with proper row/col/span structure.
- New module src/tables/structured.rs: token state machine, polygon→AABB,
crop-px→page-pt, rowspan/colspan-aware cell layout, markdown emitter.
Accepts both 4-element rects and 8-element 4-corner polygons.
- New public extract_tables_with_structure_mem in src/lib.rs that reuses
extract_page_text_items, region_overlaps_item, and the shared region
text-collection helper. No existing public function modified.
- napi binding extractTablesWithStructure mirroring the existing
extractTablesInRegions shape (f64 in JS → f32 internally).
- 14 unit tests + 5 integration tests, including a real-PDF gold-standard
match against bits_pilani_feedback.pdf.

* TSR follow-ups: header-aware separator, cells API, v1.6.0
- cells_to_markdown emits the separator after the LAST row that contains
is_header=true cells, falling back to "after row 0" when no header is
flagged. Multi-row theads now render correctly. Three new unit tests
cover: multi-row header, header not on row 0, no headers (fallback).
- New public extract_tables_with_structure_cells_mem returning
Vec<Vec<StructuredCell>> so callers can drive their own rendering or
debug overlays without re-doing the parse + extraction. The markdown
variant now wraps it. The previously-unused page_pt_bbox field is
surfaced through this API.
- New napi binding extractTablesWithStructureCells + StructuredCellJs.
- Bump @firecrawl/pdf-inspector to 1.6.0.
