`0.8.3` — Treasury custody and redemption hardening

Refreshed generated IDL, contract bindings, and public SDK types against omegax-protocol v0.3.1.
Updated reserve-domain bootstrap behavior so buildCreateDomainAssetVaultTx(...) requires a concrete vault token account.
Reflected the custody-aware inflow surface: sponsor funding, premium payments, and LP capital deposits require source token account, vault token account, asset mint, and token program accounts.
Reflected the redemption hardening: redemption requests and queue processing pass shares only, while asset payouts are derived on-chain from class NAV and queued redemption state.

Fixed buildOpenMemberPositionTx(...) so invite-only enrollment keeps inviteAuthorityAddress as an optional signer account, matching the canonical open_member_position contract.
Added regression coverage for invite-authority account metas so token/invite-gated member builders do not silently degrade back to open-member posture.
Kept the package on the devnet-first public release track while preserving the current canonical contract target.

Refreshed the generated IDL, contract bindings, and public SDK types against the latest public omegax-protocol v0.3.0 surface.
Added parity for the linked protection-claim settlement hardening so SDK consumers see the current obligation-first liability path.
Kept the package on the devnet-first public release track while preserving the current canonical contract target.

Added first-class SDK coverage for the current oracle and schema registry surface, including canonical builders and generated contract parity for oracle profiles, pool oracle controls, outcome schemas, and schema dependency ledgers.
Exported the new @omegax/protocol-sdk/oracle module for attestation workflows, including createOracleSignerFromEnv(...), createOracleSignerFromKmsAdapter(...), and attestOutcome(...).
Added buildAttestClaimCaseTx(...) plus the supporting generated bindings and PDA helpers so oracle services can anchor schema-bound claim-case attestations on-chain without dropping to custom instruction packing.
Refreshed protocol bindings, PDA helpers, and parity coverage so the SDK matches the latest public protocol surface.
Kept the package on the devnet-first public release track while preserving the current v0.3.0 contract target.

Shipped the canonical health-capital-markets SDK surface for governance, reserve domains, health plans, claims, obligations, capital classes, allocations, and reserve-aware read models.
Kept the public SDK surface and docs focused on the canonical health capital markets model.
