Implements the StructTree parser (Phase 7.1.1) with: - Depth-first walker over /StructTreeRoot via /K array - Support for all four /K entry types: StructElem, MCID, MCR, OBJR - /RoleMap resolution with chain handling and cycle detection - /Lang inheritance through the structure tree - /ActualText inheritance (applies to all descendant content) - Public API: StructureType, StructElemNode, StructTreeRoot, RoleMap, Kid Acceptance criteria: - PASS: All four /K element kinds handled without crashing - PASS: /RoleMap chains resolve to standard type or NonStruct - PASS: /Lang and /ActualText inherit correctly down tree - PASS: Unit tests for Word RoleMap (Heading1 -> H1) - PASS: Unit tests for nested /Lang and /ActualText scope - PASS: Public type StructElemNode documented in core crate References: - Plan section 7.1 StructTree Exploitation (lines 2547-2549, 2552-2553) - PDF 1.7 spec 14.7.4 (Structure Tree) and 14.8.4 (Standard Structure Types) Co-Authored-By: Claude Code <noreply@anthropic.com>
