jedarden 16ca205a1b feat(pdftract-66ykq): implement CCITTFaxDecode passthrough with diagnostics
- Add STREAM_INVALID_CCITT diagnostic code for missing/invalid /Columns
- Modify CCITTFaxDecoder to use default /Columns (1728) when missing
- Emit STREAM_INVALID_CCITT diagnostic when /Columns is missing
- Emit OCR_CCITT_UNSUPPORTED diagnostic when full-render and libtiff unavailable
- Add unit tests for CCITT decoder parameter parsing and passthrough

Acceptance criteria:
- CCITT stream with full-render + libtiff → pass-through, no diagnostic
- CCITT stream WITHOUT full-render → OCR_CCITT_UNSUPPORTED diagnostic
- /K=-1 /Columns=2480 /BlackIs1=true → all 3 params recorded on ParsedCCITTParams
- Missing /Columns → STREAM_INVALID_CCITT diagnostic + default width 1728
- Round-trip test with CCITT fixture data
