Add BBolt rate limiting and tune Badger defaults for large archives (v0.48.12)

- Increase Badger cache defaults: block 512→1024MB, index 256→512MB
- Increase serial cache defaults: pubkeys 100k→250k, event IDs 500k→1M
- Change ZSTD default from level 1 (fast) to level 3 (balanced)
- Add memory-only rate limiter for BBolt backend
- Add BBolt to database backend docs with scaling recommendations
- Document migration between Badger and BBolt backends

Files modified:
- app/config/config.go: Tuned defaults for large-scale deployments
- main.go: Add BBolt rate limiter support
- pkg/ratelimit/factory.go: Add NewMemoryOnlyLimiter factory
- pkg/ratelimit/memory_monitor.go: New memory-only load monitor
- CLAUDE.md: Add BBolt docs and scaling guide

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
