This updates the flake overlay setup to match the mkFlake-based layout and the split overlay pattern (overlays/external.nix + overlays/patches.nix). Overlays are now sourced directly from overlays/*.nix without a compatibility default.nix.

Overlay loading moved to direct file imports in flake.nix
- Changed overlay mapping to import each overlay file with flake inputs:
```
overlays = modules.mapModules ./overlays (path: import path inputs);
```
- This allows overlay files to consume flake inputs explicitly and keeps overlay discovery centralized in flake.nix.
overlays/external.nix converted to a real overlay function
- Replaced placeholder attrset with an overlay function signature (final: prev:).
- Composes external overlays from flake inputs in one place:
  - sentinel.overlays.default
  - hyprland.overlays.default
  - cachyos.overlays.pinned
  - gaming-edge.overlays.default
  - quickshell.overlays.default
  - hyprpwcenter.overlays.default
Removed legacy compatibility file
- Deleted overlays/default.nix.
- Overlay behavior now comes exclusively from overlays/*.nix imported by flake.nix.
