Changes

---

Points to Note

9 Features Return None

Due to agave-feature-set 3.0.0 limitations (Solana SDK 3.1.0 not published to crates.io yet), these features return None:

• AccountDataDirectMapping
• ProvideInstructionDataOffsetInVmR2
• IncreaseCpiAccountInfoLimit
• VoteStateV4
• PoseidonEnforcePadding
• FixAltBn128PairingLengthCheck
• LiftCpiCallerRestriction
• RemoveAccountsExecutableFlagChecks
• DisableRentFeesCollection

Follow-up Required

When Solana SDK 3.1.0 is released:

1. Update Cargo.toml dependencies to 3.1.0
2. Add missing imports to svm.rs
3. Change the 9 None mappings to Some(feature_name::id())
4. Update test assertion from 9 unmapped to 0 unmapped
