jedarden a20647a4a6 feat(pdftract-njde): implement font fingerprint cache (Level 3) ... Implement Level 3 of the encoding fallback chain. Hash the raw decoded font program bytes (/FontFile, /FontFile2, /FontFile3) with SHA-256 and look up the 32-byte digest in a compile-time phf::Map. - build.rs: generate_font_fingerprints() reads JSON, builds phf::Map - src/font/fingerprint.rs: FontFingerprint, CachedFingerprint, lookup API - build/font-fingerprints.json: empty database (placeholder) Acceptance criteria: - Empty JSON produces valid phf::Map - Hash is stable across runs - Lookup of unknown digest returns None - Binary footprint < 500KB for 200-font DB (empty = negligible) Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>		2026-05-23 21:27:24 -04:00
