Release v0.0.23

Breaking Changes 🚨

• Preserve --port CLI override across configuration reloads, changing previous behavior where CLI flags could be overridden by config.

New Features 🎉

• Add hot reload support for the configuration file using an fsnotify-based file watcher.
• Introduce AtomicConfig with atomic.Pointer for lock‑free reads.
• Support SIGHUP as a manual reload trigger on Unix systems.

• Allow API key, base URLs, model routing, and fallbacks to reload live without restart.
• Preserve the --port CLI override across configuration reloads.

Bug Fixes 🐞

• Preserve the old configuration during reload and log watcher errors instead of silently ignoring them.
• Move change detection before atomic store so the old config remains accessible while comparing host/port and timeout changes.
• Wrap the config.WatchConfig goroutine to capture and log startup errors.
• Improve resource cleanup in the config watcher.
• Add error logging for absolute path and watcher creation failures.
• Enhance config watcher and improve concurrency handling in AtomicConfig.

Improvements 🚀

• Refactor server struct fields for better tidiness.
• Optimize concurrency handling within AtomicConfig.
• Add comprehensive tests for atomic config and watcher functionality.

Documentation 📚

• Update README and internal comments to document hot reload capabilities and SIGHUP usage.
• Revise configuration documentation to reflect live reload of API key, base URLs, model routing, and fallbacks.

Chores 🧹

• Update go.mod and go.sum with new dependencies (fsnotify, slog).
• Incorporate CI/CD pipeline updates for new test files.
• Refactor internal files for improved organization and code quality.
