Map Fee allocation ratios from StakeDAO

[Xeonus]

We are currently missing the veBAL / vlAURA allocation shares because StakeDAOs votemarket aggregates everything.
More specifically we are missing following fields:

auraIncentives
auravebalShare
auraIncentivesPct

since fee run for timestamp periodStart=1767225600

Use the StakeDAO VoteMarket Analytics data (hosted on GitHub) to retroactively determine the Aura/BAL split after each round completes.

Data Sources Available

1. Balancer-level analytics (all veBAL voters):
   - Metadata: https://raw.githubusercontent.com/stake-dao/votemarket-analytics/main/analytics/votemarket-analytics/balancer/rounds-metadata.json
   - Per-round: https://raw.githubusercontent.com/stake-dao/votemarket-analytics/main/analytics/votemarket-analytics/balancer/{roundId}.json
   - Contains: totalDepositedUSD, per-gauge totalDeposited, nonBlacklistedVotes, efficiency
2. Aura/vlAURA-specific analytics (Aura voters only):
   - Metadata: https://raw.githubusercontent.com/stake-dao/votemarket-analytics/main/analytics/votemarket-analytics/vlaura/balancer/rounds-metadata.json
   - Per-round: https://raw.githubusercontent.com/stake-dao/votemarket-analytics/main/analytics/votemarket-analytics/vlaura/balancer/{roundId}.json
   - Contains: Same structure but filtered to Aura voter proxy's voting power only

        "dollarPerVote": 0.00132,
        "incentiveDirected": 8442.01,      // BAL inflation directed

    ]
  }

Calculation Method

For a given fee allocation period (biweekly):

1. Match the period to VoteMarket rounds: Use endVoting timestamps from rounds-metadata.json to find the round(s) that overlap with the fee allocation period (periodStart → periodEnd). A biweekly period typically spans 2
   weekly VoteMarket rounds.
2. Fetch both Balancer and vlAURA data for the matching round(s).
3. Calculate Aura's share per gauge:
   For each gauge in the allocation:
   aura_votes = vlaura_round.analytics[gauge].nonBlacklistedVotes
   total_votes = balancer_round.analytics[gauge].nonBlacklistedVotes
   aura_share_for_gauge = aura_votes / total_votes
4. Calculate aggregate split:
   aura_incentives = sum(pool.total_to_incentives_usd × aura_share_for_gauge[pool.gauge])
   bal_incentives = total_incentives - aura_incentives
   aura_vebal_share = aura_incentives / total_incentives
5. Alliance pools exception: Pools with is_whitelist=true (alliance/aura-only) are 100% Aura by definition — no lookup needed.
