Relocate SSH inventory and rbw socket wiring from `modules/lib/` to
dedicated `modules/ssh/` modules to improve logical grouping.
- Move `ssh-inventory.nix` to `modules/ssh/inventory.nix`.
- Move `rbw-ssh-socket.nix` to `modules/ssh/rbw.nix`.
- Relocate `users-merge.nix` logic into `modules/system/users.nix` to
reduce dependency on generic library modules.
- Update `docs/conventions.md` to reflect new module paths.
- Refactor `modules/deploy/navi.nix` to use a local helper for
generating Navi hive configurations.
- Add Pi5 specific Niri KDL configuration snippets.
Refactor the SSH configuration generation to reduce duplication and
improve efficiency.
- Extract `IdentityFile` line generation into a shared variable in
`ssh-inventory.nix` to ensure consistency between per-host and
gitea blocks.
- Optimize `selectedHosts` resolution in `home-manager/default.nix`
by reusing `activeHosts` when the "all" wildcard is used.
- Tighten IPv4 regex matching in `ssh-inventory.nix` using anchors.
- Update `users-merge.nix` to propagate `extraIdentities` to the
rbw outbound configuration.
- Set default `authorizedHosts` to "all" for inbound SSH users.
- Introduced a new module `rbw-ssh-socket.nix` to manage SSH_AUTH_SOCK for rbw.
- Updated `default.nix` to utilize the new SSH socket variable for session management.
- Refactored Bash and Fish shell configurations to use the new module for setting SSH_AUTH_SOCK, improving maintainability and consistency across shell environments.
- Introduced a new private default settings file for Dank Material Shell (DMS) to manage user-specific settings.
- Updated DMS home-manager module to generate a settings seed file, merging extra right-bar widgets into the first-run configuration.
- Added support for dynamic inclusion of DMS window rules based on user configuration.
- Enhanced the Niri configuration with a preference for no client-side decorations and improved keybindings for bar toggling.
