feat: Improve CMap handling with binary CMap support, inline ToUnicode, and fallback decoding ...
- Add pdf.js binary CMap (bcmap) parser for Japan1/GB1/CNS1 CID fonts
- Support inline ToUnicode streams (not just object references)
- Add CMapDecisionCache for heuristic primary vs remapped CMap selection
- Build fallback CMaps from embedded font data and CIDSystemInfo
- Handle simple fonts without ToUnicode via embedded font cmap
- Add Symbol/Wingdings/ZapfDingbats font decoding fallback
- Support usecmap chaining in both text and binary CMap formats
- Scan XObject Forms for text operators in detector
- Change default detection strategy from EarlyExit to Sample(8)
