84b4448648 feat(pdftract-5qca): implement form_fields JSON output + schema integration 
Phase 7.4.5 implementation: Wire combined Vec<(String, FormFieldValue)> from
combiner into document-level /form_fields JSON output with tagged union schema.

- Add FormFieldJson, FormFieldTypeJson, FormFieldValueJson, ChoiceValueJson to schema
- Add form_fields: Vec<FormFieldJson> to ExtractionResult (always emitted, empty when none)
- Implement acro_field_to_value() converter for Phase 7.4.2 type-specific extraction
- Wire form field extraction in extract_pdf(): walk AcroForm, extract XFA, combine with XFA-wins
- Add convert_form_field_to_json() helper for FormFieldValue → FormFieldJson conversion
- Update docs/schema/v1.0/pdftract.schema.json with form_fields $defs and required field
- Add form_fields_to_markdown() to markdown module for Form Fields footer table

Schema shape: /form_fields is array of {name, type, value, default?, page_index?, rect?,
required, read_only, multiline?, max_length?, options?, multi_select?, selected?,
state_name?, pushbutton?, radio?}. Type field is tagged enum: "text", "button", "choice",
"signature". Value field varies by type (string|boolean|string|array|uint|null).

67b3fde4d6 feat(pdftract-j6yd): implement signatures array output + validation_status enum + schema integration 
Add document-level /signatures array output per Phase 7.3 of the plan.

Changes:
- Add SignatureJson struct to schema module with all signature metadata fields
- Update ExtractionResult to include signatures: Vec<SignatureJson>
- Integrate signature extraction into extract_pdf() pipeline
- Update result_to_json() to include signatures in JSON output
- Update JSON schema with signatures array and SignatureJson definition
- Add markdown sink signatures footer when signatures are present
- Add comprehensive tests for signature JSON serialization and validation

Acceptance criteria:
- Schema tests: 5/5 signature JSON tests pass
- Markdown sink emits Signatures footer when count > 0
- PyO3 binding automatically handles Vec<SignatureJson> via serde
- docs/schema/v1.0/pdftract.schema.json updated with signatures shape

Verification note: notes/pdftract-j6yd.md

92e90af0b0 feat(pdftract-zy2jx): generate JSON Schema from Rust output types 
- Add schemars dependency to pdftract-core (v1.2)
- Add JsonSchema derives to output types (ExtractionResult, PageResult, ExtractionMetadata, SpanJson, BlockJson, CellJson, RowJson, TableJson, ExtractionQuality, Receipt, ReceiptsMode)
- Create xtask/src/bin/gen_schema.rs for schema generation
- Add gen-schema command to xtask main.rs
- Generate docs/schema/v1.0/pdftract.schema.json using Draft 2020-12

Schema includes:
- $schema: "https://json-schema.org/draft/2020-12/schema"
- $defs with all output type definitions
- Proper type annotations for all fields

d14ec92fcb feat(pdftract-3zhf): add unified TableDetector::detect entry point 
Add unified detect() method to TableDetector that combines both
line-based and borderless table detection pipelines. This completes
the coordinator bead for Phase 7.2: Table Detection and Structure
Reconstruction.

All child beads (7.2.1-7.2.6) are closed:
- 7.2.1: Line-based detection (path segment clustering)
- 7.2.2: Borderless detection (x0 alignment heuristic)
- 7.2.3: Span-to-cell assignment (centroid containment)
- 7.2.4: Header row detection (bold + StructTree TH)
- 7.2.5: Merged cell detection (missing interior edges)
- 7.2.6: Table JSON output schema integration

Critical tests pass:
- 5x3 bordered table (15 cells extracted)
- Merged header cell colspan=3
- Borderless 3-column table detection
- Two-page table continuation detection
