rl-2511: Move entries from incorrect sections

- Everything related to `bower` was removed, as it is deprecated and not used by anything in nixpkgs.

- `reaction` has been updated to version 2, which includes some breaking changes.

  For more information, [check the release article](https://blog.ppom.me/en-reaction-v2).

- `mealie` has been updated to 3.0.2: This update introduces breaking changes in some API endpoints (see the [release changelog](https://github.com/mealie-recipes/mealie/releases/tag/v3.0.0)).

- The `offrss` package was removed due to lack of upstream maintenance since 2012. It's recommended for users to migrate to another RSS reader

- `installShellFiles`: Allow installManPage to take a piped input, add the `--name` flag for renaming the file when installed. Can also append `--` to opt-out of all subsequent parsing.

- The systemd initrd will now respect `x-systemd.wants` and `x-systemd.requires` for reliably unlocking multi-disk bcachefs volumes.

- `neovim`: Added support for the `vim.o.exrc` option, the `VIMINIT` environment variable, and sourcing of `sysinit.vim`.

  See the neovim help page [`:help startup`](https://neovim.io/doc/user/starting.html#startup) for more information, as well as [the nixpkgs neovim wrapper documentation](#neovim-custom-configuration).

- `cloudflare-ddns`: Added package cloudflare-ddns.

- [`homebox` 0.20.0](https://github.com/sysadminsmedia/homebox/releases/tag/v0.20.0) changed how assets are stored and hashed. It is recommended to back up your database before this update. In particular, `--storage-data` was replaced with `--storage-conn-string` and `--storage-prefix-path`. If your configuration set `HBOX_STORAGE_DATA` manually, you must migrate it to `HBOX_STORAGE_CONN_STRING` and `HBOX_STORAGE_PREFIX_PATH`.

- GIMP now defaults to version 3. Use `gimp2` for the old version.

### Breaking changes {#sec-nixpkgs-release-25.11-lib-breaking}

- `reaction` has been updated to version 2, which includes some breaking changes.

  For more information, [check the release article](https://blog.ppom.me/en-reaction-v2).

- `lib.mapAttrsFlatten` has been removed, following its deprecation in NixOS 24.11. Use `lib.attrsets.mapAttrsToList` instead.

- `lib.attrsets.cartesianProductOfSets` has been removed, following its deprecation in NixOS 24.11. Use `lib.attrsets.cartesianProduct` instead.

  and called `setup.py` from the source tree, which is deprecated.

  The modern alternative is to configure `pyproject = true` with `build-system = [ setuptools ]`.

- `boot.enableContainers` is only turned on when a declarative NixOS container is defined in `containers`.

  If you use the `nixos-container` tool for imperative container management, set `boot.enableContainers = true;` explicitly.

### Deprecations {#sec-nixpkgs-release-25.11-lib-deprecations}

- `lib.options.mkAliasOptionModuleMD` is now obsolete; use the identical [`lib.options.mkAliasOptionModule`] instead.

### Additions and Improvements {#sec-nixpkgs-release-25.11-lib-additions-improvements}

- `neovim`: Added support for the `vim.o.exrc` option, the `VIMINIT` environment variable, and sourcing of `sysinit.vim`.

  See the neovim help page [`:help startup`](https://neovim.io/doc/user/starting.html#startup) for more information, as well as [the nixpkgs neovim wrapper documentation](#neovim-custom-configuration).

- `cloudflare-ddns`: Added package cloudflare-ddns.

- `lib.cli.toCommandLine`, `lib.cli.toCommandLineShell`, `lib.cli.toCommandLineGNU` and `lib.cli.toCommandLineShellGNU` have been added to address multiple issues in `lib.cli.toGNUCommandLine` and `lib.cli.toGNUCommandLineShell`.

- The `services.polipo` module has been removed as `polipo` is unmaintained and archived upstream.

- `boot.enableContainers` is only turned on when a declarative NixOS container is defined in `containers`.

  If you use the `nixos-container` tool for imperative container management, set `boot.enableContainers = true;` explicitly.

- `virtualisation.lxd` has been removed due to lack of Nixpkgs maintenance. Users can migrate to `virtualisation.incus`, a fork of LXD, as a replacement. See [Incus migration documentation](https://linuxcontainers.org/incus/docs/main/howto/server_migrate_lxd/) for migration information.

- `virtualisation.libvirtd` now uses OVMF images shipped with QEMU for UEFI machines. `virtualisation.libvirtd.qemu.ovmf` has been removed.
