Implement PID-controlled adaptive rate limiting for database operations
- Add LoadMonitor interface in pkg/interfaces/loadmonitor/ for database load metrics
- Implement PIDController with filtered derivative to suppress high-frequency noise
- Proportional (P): immediate response to current error
- Integral (I): eliminates steady-state offset with anti-windup clamping
- Derivative (D): rate-of-change prediction with low-pass filtering
- Create BadgerLoadMonitor tracking L0 tables, compaction score, and cache hit ratio
- Create Neo4jLoadMonitor tracking query semaphore usage and latencies
- Add AdaptiveRateLimiter combining PID controllers for reads and writes
- Configure via environment variables:
- ORLY_RATE_LIMIT_ENABLED: enable/disable rate limiting
- ORLY_RATE_LIMIT_TARGET_MB: target memory limit (default 1500MB)
- ORLY_RATE_LIMIT_*_K[PID]: PID gains for reads/writes
- ORLY_RATE_LIMIT_MAX_*_MS: maximum delays
- ORLY_RATE_LIMIT_*_TARGET: setpoints for reads/writes
- Integrate rate limiter into Server struct and lifecycle management
- Add comprehensive unit tests for PID controller behavior
Files modified:
- app/config/config.go: Add rate limiting configuration options
- app/main.go: Initialize and start/stop rate limiter
- app/server.go: Add rateLimiter field to Server struct
- main.go: Create rate limiter with appropriate monitor
- pkg/run/run.go: Pass disabled limiter for test instances
- pkg/interfaces/loadmonitor/: New LoadMonitor interface
- pkg/ratelimit/: New PID controller and limiter implementation

Refactor export functionality in App.svelte to support both GET and POST methods for event exports, enhancing flexibility in user permissions. Update server-side handling to accommodate pubkey filtering and improve response handling for file downloads. Adjust UI components to reflect these changes, ensuring a seamless user experience.
