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

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
