Add M1 design documents: law script + API shapes (3 designs, recommend B)

- M1 law script format decision doc recommends S-expressions with fixed
  combinators for non-Turing provability, auditability, and immutability
  at runtime (S99). Includes example constitution with all L1-L5 invariants.

- M1 trader-wallet-marketplace API designs: compare 3 radically different
  shapes (minimal tokens, event-sourced ledger, GraphQL). Recommend Design B
  (ledger) for auditability, replay capability, and SAE integration.

- Ada config: core_config.gpr with GNAT 2022 compiler flags.
