Continuous-aggregate OHLC rollups

[Miracle656]

Background

Computing candles on the fly is expensive. Materialized/continuous aggregates give fast OHLC queries at scale.

What to build

Add continuous aggregates (TimescaleDB hypertable + continuous aggregate, or scheduled materialized views) for 1m/1h/1d OHLC, with a refresh policy and a query endpoint that reads the rollup.

Key files

• prisma/schema.prisma / sql/ migrations
• src/api/candles.ts

Acceptance criteria

• Rollups refresh incrementally
• Candle endpoint reads the aggregate, not raw rows
• Benchmark shows the speedup vs on-the-fly
