…XXL#76) - Add StakingService with stake, unstake, claimRewards, autoCompound, setAutoCompound, and getStakingOpportunities - Add StakingDTOs (StakeDto, UnstakeDto, AutoCompoundConfigDto, etc.) - Wire StakingService into DeFiModule and expose REST endpoints: GET /defi/staking POST /defi/staking POST /defi/staking/:id/unstake POST /defi/staking/:id/claim POST /defi/staking/:id/compound PUT /defi/staking/:id/auto-compound GET /defi/staking/opportunities - Add 8 unit tests for StakingService covering all core methods - Fix pre-existing PortfolioConstraintService bugs: * Category allocation check now uses warningThresholdPercent to distinguish error vs warning boundary * Add getCategoryConcentrationPenalty() for asset-type concentration risk scoring (fixes risk-score-near-limit warning threshold test)

Summary
Implements staking and yield optimization automation as described in issue #76.
Changes
New: StakingService (
src/defi/services/staking.service.ts)stake()— opens a new staking position against a DeFi protocol adapterunstake()— reduces/closes a staking positiongetStakingPositions()— lists all staking positions for a userclaimRewards()— claims accumulated staking rewards and persists yield recordsautoCompound()— re-stakes claimable rewards when auto-compound is enabledsetAutoCompound()— toggles auto-compound on a positiongetStakingOpportunities()— discovers staking APY across all protocol adaptersNew: StakingDTOs (
src/defi/dto/staking.dto.ts)StakeDto,UnstakeDto,AutoCompoundConfigDto,StakingPositionResponseDto,StakingOpportunityDtoNew: Unit tests (
src/defi/services/staking.service.spec.ts)8 tests covering: stake, unstake (partial + full close + 404), getStakingPositions, claimRewards, autoCompound (disabled + enabled), setAutoCompound, getStakingOpportunities (capability filter)
Updated: DeFiModule + DeFiController
REST endpoints added:
/defi/staking/defi/staking/defi/staking/:id/unstake/defi/staking/:id/claim/defi/staking/:id/compound/defi/staking/:id/auto-compound/defi/staking/opportunitiesFix: PortfolioConstraintService (pre-existing test failures)
