feat: Cloud Function to aggregate matchLog into playerProfile

[ibloud]

Summary

Build a post-game aggregator that reads completed matchLogs and updates playerProfiles/{playerToken} (Phase 1 key), with did support for Phase 2 migration.

Implementation

• Trigger on match completion (or scheduled processor of completed logs).
• Compute and persist:
  • matchesPlayed, wins, losses, winRate
  • acpl
  • veilRate, opponentVeilRate
  • sacrificeRate
  • comebackWins
  • inversionClause totals (total, blind, seal)
• Upsert playerProfiles with createdAt/updatedAt.
• Keep researchConsent default false.

Acceptance Criteria

• Profile doc updates correctly after a completed match.
• Metrics are deterministic from the same matchLogs.
• Re-processing is idempotent (no double-counting).
