Add fields 8-14 to the Proposal protobuf message for compact block propagation. These optional fields carry tx hashes, app-injected txs, block header, last commit, evidence, and proposer address — enabling validators to reconstruct blocks from their local mempool without waiting for block parts to gossip. Fields are NOT included in CanonicalProposal, so signing is unaffected. Backward compatible: old validators ignore unknown fields.
…erialization Add TxKeys, NonMempoolTxs, NonMempoolIndices, CompactHeader, CompactLastCommit, CompactEvidence, and ProposerAddress fields to the native Proposal type. Update ToProto/ProposalFromProto for serialization. Add HasCompactData() helper and headerFromProtoNoValidate() for safe deserialization without premature validation.
Default true. When enabled, proposers include compact block data in Proposal messages and receivers attempt mempool-based reconstruction.
Add GetTxsForKeys(keys []TxKey) to the Mempool interface for O(1) batch tx lookup by SHA-256 key. CListMempool uses the existing txsMap (sync.Map) for lock-free reads. NopMempool returns all missing.
Proposer side: populate TxKeys, NonMempoolTxs, CompactHeader, etc. in defaultDecideProposal when compact_proposals is enabled. Receiver side: on proposal receipt, attempt block reconstruction via tryReconstructBlock(). If hash matches proposal.BlockID, set ProposalBlock immediately and trigger enterPrevote without waiting for block parts. Falls back to traditional gossip on failure. Add 3 metrics: compact_reconstructed, compact_missed, compact_hash_mismatch. Wire mempool into consensus State via StateMempool option.
- Rename proto/dydxcometbft to proto/perpxcometbft - Update README.md to PerpX/perpx-chain branding - Update organization references to 1119-Labs - Update branch naming to perpx-fork - Regenerate protobuf files with new package names - Update mempool import path for new proto package location

Summary
Implements compact block proposals (Sei Twin-Turbo style) to reduce block propagation latency. The proposer includes tx hashes + block metadata in the Proposal message itself, enabling validators to reconstruct blocks from their local mempool instantly — without waiting for block parts to gossip.
