Addresses @0x-r4bbit's review:
- lez-authority now provides an Authority(Option<[u8;32]>) newtype and an
Ownable trait (require_owner / transfer_ownership / renounce_ownership);
programs embed the authority slot in their account type instead of calling
a wrapper. Replaces the old AuthoritySlot.
- TokenDefinition::Fungible embeds authority: Authority; TokenDefinition
implements Ownable.
- Fold mint authority into NewFungibleDefinition { mint_authority: Option<AccountId> };
remove the separate NewFungibleDefinitionWithAuthority instruction.
- mint/set_authority authorize against the definition account itself (its id
must match the stored authority and be authorized in the tx), restoring the
2-account mint shape and supporting PDA authorities.
- Fix AMM: the pool-definition PDA is now the LP token's mint authority, so the
AMM mints LP at creation and on add-liquidity (was permanently revoked).
- Instruction params use AccountId; remove LP-0013-specific comments.
- Regenerate token/amm/ata/stablecoin IDLs.
Tests: lez-authority 8, token unit 56, token/amm/stablecoin/ata integration all
green under RISC0_DEV_MODE=1; fmt + clippy clean.
