Subject: [PATCH] fix: resolve CHANGELOG.md path issue for Docker deployment

- Update changelog.go to use binary directory as base path
  - Uses os.Executable() instead of relative path '..'
  - Automatically adapts to local and Docker environments

- Modify server Dockerfile build context
  - Change context from ./server to project root (.)
  - Update COPY commands for new context
  - Add CHANGELOG.md to container image

- Update AGENTS.md guidelines
  - Explicitly specify relative path format for file references

This ensures the changelog API works correctly in both local development
and Docker deployment environments.
