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

Adjust ACL behavior for "none" mode and make query cache optional

This commit allows skipping authentication, permission checks, and certain filters (e.g., deletions, expirations) when the ACL mode is set to "none" (open relay mode). It also introduces a configuration option to disable query caching to reduce memory usage. These changes improve operational flexibility for open relay setups and resource-constrained environments.

Add Relay functionality for managing startup and shutdown processes

- Introduced a new package `run` with a `Relay` struct to manage the lifecycle of a relay instance.
- Implemented `Start` and `Stop` methods for initializing and gracefully shutting down the relay, including options for log capturing and data directory cleanup.
- Added methods to retrieve captured stdout and stderr logs.
- Enhanced configuration handling for data directory and logging based on user-defined options.
