fenleon cfd6cd4e71 NAC sign ported to Kotlin (NacSign): full mint in-repo; spec rev 31; NacMint facade ...

The verified pure-python sign model (sig_hand/sig_init/sig_tail) is now
transcribed to Kotlin: NacSignTablesData.kt carries 102 tables as generated
base64 source (ClearAdiTablesData precedent, provenance header), NacSign.kt
runs the pipeline (u32tab → scatter → perms → keygen → phases B–E → rounds →
genBufs → threshold-cipher tail), and NacValidation.mint computes sig16
internally — the full 517-B stamp from Kotlin inputs. Pinned by 5 synthetic
LCG vectors against the python model (208 tests, 0 failed; table images
re-decoded and compared table-by-table, 32/32). Spec rev 31; README status
updated. NacMint: minimal public facade for consumers (the imessage tool
wires ClearAnisetteProvider + the mint behind its AnisetteSource/
ValidationDataSource seams).
