v0.4.10

🔧 Critical Bug Fix

Fixed heading-map preservation of deeply nested subsections (#### and beyond).

The Problem

Heading-map entries for #### subsections were being deleted during translation. The root cause was duplicate parsing logic:

• parseDocumentComponents() used a simple 2-level parser (## and ### only)
• parseSections() had full recursive support (##-######)

This meant #### subsections were treated as content instead of structure, preventing them from being added to heading-maps.

The Solution

Refactored parseDocumentComponents() to call parseSections() internally:

• ✅ Eliminated duplicate parsing logic (DRY principle)
• ✅ Full recursive support for all nesting levels
• ✅ Single source of truth for parsing

Impact

• All 140 tests passing ✅
• No breaking changes - pure bug fix
• Bundle size: 1941kB (unchanged)
• Test coverage: Added 6 tests for #### and ##### changes
