Performance monitoring for StarPunk

This package provides performance monitoring capabilities including:
- Metrics collection with circular buffers
- Operation timing (database, HTTP, rendering)
- Per-process metrics with aggregation
- Configurable sampling rates
- Database query monitoring (v1.1.2 Phase 1)
- HTTP request/response metrics (v1.1.2 Phase 1)
- Memory monitoring (v1.1.2 Phase 1)

Per ADR-053 and developer Q&A Q6, Q12:
- Each process maintains its own circular buffer
- Buffers store recent metrics (default 1000 entries)
- Metrics include process ID for multi-process deployment
- Sampling rates are configurable per operation type
