Adds a 4th workspace crate `aldabra-dao` for native Agora-on-Cardano DAO interaction. Multi-DAO from day one — DaoConfig per DAO at \$ALDABRA_DATA/daos/<name>.json + .active selector. Sulkta DAO and any community Agora deployment (Bob's DAO, Alice's DAO) are first-class. Phase 0 type port complete: - StakeDatum, StakeRedeemer, ProposalAction, ProposalLock, Credential - ProposalDatum, ProposalRedeemer, ProposalStatus, ProposalThresholds, ProposalTimingConfig, ProposalVotes - GovernorDatum, GovernorRedeemer - All Constr indices verified against Agora source makeIsDataIndexed + EnumIsData declarations (Stake/Proposal/Governor/Action/Status all cross-referenced) - Round-trip tests for every type Phase 1 read surface (this commit): - DaoStore: DaoConfig load/save/list/remove + active-DAO selector with first-register-becomes-active UX. 8 unit tests. - DaoReader trait + KoiosDaoReader impl for get_governor + list_stakes. list_proposals stubbed pending Phase 4 proposal-script-address discovery. - Stake address sharing handled: list_stakes filters on gov_token_policy (the shared MLabs stakes addr serves many DAOs). Stubs for upcoming phases: - agora/treasury.rs (Phase 4 — treasury spend helpers) - agora/authority_token.rs (Phase 4 — GAT mint/burn) - agora/reference_scripts.rs (Phase 2/3 — independent script-hash discovery per Sulkta's choice 2026-05-05; computed locally, never trust MLabs registry) - builder/mod.rs (per-operation Plutus tx builders, populated phase-by-phase) Spec doc + decisions: internal notes in workspace. Effects map (`ProposalDatum.effects`) kept as raw PlutusData for round-trip integrity until Phase 4 (proposal create) needs typed access. ExUnits strategy locked: Koios tx_evaluate from day one (no hardcoded values). Wired up in Phase 2 alongside reference-script discovery.
