Refactor home modules and update configs

- Remove unused `pkgs` import from hardware and adjust user stateVersion
to 25.11 with updated wheel comment. - Split Bash aliases and functions
into separate modules and rename `bash.nix` to `bash/default.nix` with
imports. - Delete old Bash alias/function files and consolidate them
under the new structure. - Simplify `bat.nix` by removing commented
style lines. - Increase Cava `frame_rate` from 60 to 144 and clean up
legacy color settings. - Refactor Chromium configuration: separate
extensions into `extensions.nix` and use a minimal default module. -
Replace large Kitty config with minimal enable/module and import
`extra-config.nix` and `settings.nix`. - Overhaul Librewolf setup:
extract profiles, extensions, search, and settings into dedicated files.
- Update home `default.nix` imports to reflect new module paths and
remove obsolete references. - Modularize SwayNC by moving settings and
style to separate files. - Add explicit Vesktop package definition. -
Remove old VSCode module; introduce VSCodium with profile-based
extensions, keybindings, and user settings. - Reorganize XDG portal and
desktop entries into modular files. - Rebuild Zed configuration: split
user settings, language models, languages, LSP, extensions, and extra
packages into distinct files.
