Implements Phase 7.1.2: StandardType -> BlockKind mapping for converting walked StructElem nodes into the BlockKind taxonomy used by Phase 4 output. Changes: - Add BlockKind enum with all output block kinds (paragraph, heading with level, table, list, list_item, figure, caption, code, block_quote, toc, formula, reference, note, form_field_struct, inline, structural_container, artifact, unknown) - Add MappingResult struct bundling block_kind, is_emitted flag, and optional diagnostic - Add structure_type_to_block_kind() function for pure type mapping - Add map_element_to_block() function as primary mapping API - Add is_artifact() placeholder for Phase 3.4 marked-content integration - Add 32 comprehensive unit tests covering all mapping paths Key features: - Complete type mapping for all 40+ PDF standard structure types - Heading level extraction: H->level 1, H1..H6->level 1..6 - Inline elements (Span, Quote) map to Inline (not emitted as blocks) - Structural containers (Document, Part, Sect, Div, etc.) map to StructuralContainer (descend without emitting) - Unknown types emit diagnostic and fall back to paragraph Acceptance criteria: - Every Standard structure type has a mapping decision - Critical test: H1/H2 -> heading level 1/2 - Unit tests: list nesting, table grouping, span passthrough - Unknown-type fallback path emits a diagnostic line Refs: Plan section 7.1 lines 2552-2553
