Allow overriding MAX_TERMINAL_BUFFER_SIZE, TRIM_TERMINAL_TO, MAX_TEXT_OUTPUT_SIZE,
TRIM_TEXT_TO, and MAX_MESSAGES via CODEMAN_* env vars, falling back to existing
defaults. Enables users with fewer sessions or more RAM to tune buffer sizes
without patching source.

- Add Disposable, BufferConfig, MemoryMetrics, CleanupRegistration types
- Create src/config/buffer-limits.ts with consolidated buffer size constants
- Create src/config/map-limits.ts with Map size limits to prevent unbounded growth
- Implement BufferAccumulator utility with configurable trim and onTrim callback
- Implement LRUMap with automatic eviction and O(1) operations
- Implement CleanupManager for unified resource cleanup with isStopped guard
- Add comprehensive tests for all new utilities
This lays the foundation for memory leak prevention and performance improvements.
