jedarden 7429a67d08 feat(pdftract-juc): implement Standard 14 font metrics registry

- Add build.rs that generates compile-time std14 metrics from JSON
- Add std14.rs module with Std14Metrics struct and get_std14_metrics()
- Add build/std14-metrics.json with AFM-derived widths for all 14 fonts
- Re-export Std14Metrics, NamedEncoding, get_std14_metrics in lib.rs

Acceptance criteria:
- All 14 Standard fonts (Courier, Helvetica, Times, Symbol, ZapfDingbats
  and their variants) return valid metrics from the registry
- Subset-prefixed names (ABCDEF+Helvetica) resolve via strip_subset_prefix()
- Width tables match Adobe AFM data within rounding tolerance
- Binary footprint < 60 KB (generated source: 20 KB, actual data ~8 KB)
