1. default.nix

The entrypoint of overlays, it execute and import all overlay files in the current directory with the given args.

2. fcitx5

fcitx5's overlay, add my customized Chinese input method - 小鹤音形输入法

This overlay provides:

• Custom rime data for 小鹤音形输入法 (Flypy input method)
• Cross-platform support for both Linux (fcitx5-rime) and macOS (squirrel)
• Pre-configured input method settings

3. Package overlays

• computer-use-linux.nix: packages pkgs/computer-use-linux.
• cua-driver.nix: packages pkgs/cua-driver (used by the computer-use VMs).
• smartctl-exporter/: pins prometheus-smartctl-exporter to the upstream commit carrying PR #329 until nixpkgs provides a version containing the fix; see overlays/smartctl-exporter/default.nix.
