This commit introduces several major performance improvements and adds robust error handling for malformed HTTP requests: Performance Optimizations: - Add database migration with BRIN indexes for time-series data and partial indexes for recent queries, significantly improving query performance - Create global StreamingPacketsPubSub system for real-time packet distribution with geographic bounds filtering using ETS for fast lookups - Refactor PacketConsumer to use Stream module for memory-efficient processing, preventing memory accumulation during batch operations - Implement dedicated BroadcastTaskSupervisor pool for async broadcast operations, preventing GenServer blocking on I/O - Increase database connection pool from 25 to 45 (production) and 15 to 30 (dev) for better concurrency support Error Handling: - Add SentryFilter to prevent Bandit.HTTPError from missing Host headers from cluttering Sentry (common with bots/scanners) - Configure custom 400 Bad Request error handling - Filter out common bot/scanner paths from error reporting All changes include comprehensive test coverage following TDD practices. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
