feat(versionaware): gate prebuilt tables behind build tag, use flat globals
Move codes_gen.go behind //go:build prebuilt_tables. Without the tag, Tables/Revisions are empty and all resolution happens via lazy JAR extraction from the device. Replace nested CompiledTable literals with flat global vars (one per method slice, one per version table). The Go compiler statically initializes flat globals in the data segment, eliminating runtime init code entirely (9.48MB map.init → 0 init code). Results (x86): - Default binary (no prebuilt): 112MB, 45ms startup - Prebuilt binary (flat globals): 123MB, 52ms startup - Original (map init): 124MB, 80ms startup
