* Remove formatter.nix and nix-auto-follow from the Dendritic module

* Remove treefmt configuration from dev

* Add treefmt configuration back to dev

* Add support for `submodules` input attribute

* Update modules/options/inputs.nix

* move functions to lib for unit-testing

* add nix-unit

* move _lib.nix to dev for testing

* fix: inputs preserve follows correctly when non empty.

added unit tests

Fix #32.

fmt

make _lib a dir

* make ./dev use flake-file from repository root

* regen

* run metadata before pruning

* nix-unit.flake-parts follows

* dev flake now references local flake-file

* follow more nix-unit inputs

* run flake metadata on CI

* more migrating tips

* Use diffutils instead of delta.

Fixes #33

* Do not ship templates/*/flake.lock.

Otherwise the flake.lock will always reference previous commits of flake-file and never be able to reference the latest commit. So now we instruct people to run `.#write-flake` to regen flake.nix and flake.lock right after `flake init`.

Closes #29

Based on my experience during https://github.com/vorburger/nixfiles/commit/abb2430d5dfa142f6013e6bd62cd11b9d0cbf839.

Updated image in README with a new ouroboros graphic.

because allfollow seems is more slowly maintained.

* feat(inputs): add support for attribute representation

Adds support for all flake reference attributes to the flake-file.inputs option. This allows users to specify inputs using the attribute set representation, in addition to the URL-like syntax.

* refactor merge on user defined values.

* feat: Add nix-auto-follow module

This adds nix-auto-follow as a flattening mechanism which can be
activated with a provided module.

Closes #19.

* doc: Added documentation for nix-auto-follow module

This also fixes broken link to the allfollow module.

- Move options from _options/ to options/ directory
- Convert all option files to proper flake-parts modules with options namespace
- Introduce hooks system for extensible write and check operations:
- write-hooks: run during flake generation on working copy
- check-hooks: run during flake validation on temporary copy
- Refactor prune-lock to use hooks system instead of hardcoded logic
- Update formatter option to use package type instead of command string
- Simplify write-flake.nix using new hooks architecture
- Replace hardcoded prune-lock logic with configurable hook system

BREAKING CHANGE: The formatter is now expected to return a package with meta.mainProgram,
the old behavior expected a command string.

- Create modules/_options/ directory with individual option files
- Split large options.nix into modular components:
- do-not-edit.nix: header comment option
- formatter.nix: flake formatter configuration
- inputs.nix: flake inputs with follows support
- outputs.nix: outputs function configuration
- prune-lock.nix: lock pruning options
- Simplify main options.nix using dynamic imports
- Improve code organization and maintainability

- Move allfollow.nix to modules/prune-lock/ directory
- Convert dendritic.nix to dendritic/ directory with default.nix
- Update prune-lock API from command string to program derivation
- Add _nothing.nix as example pruning app that does nothing
- Update allfollow.nix to use writeShellApplication pattern
- Rename check-flake to check-flake-file for clarity
- Add standalone prune-lock package

BREAKING CHANGE: prune-lock.command option replaced with prune-lock.program

Due to not being inherited flakeModules the allfollow module could
not be imported on the user-end. It is inherited now.

This closes #17.

It is now included by our new flakeModules.allfollow

This allows processing the flake.lock file opt-in.

It is also generic and does not depend on allfollow.

But we provide an allfollow flakeModule and also included
by default on dendritic.

flake-file now generates attributes in the following order:

- description
- outputs
- nixConfig
- inputs

The reason is that inputs tend to grow the more, nixConfig not so, and the
other two attributes are mostly static along the life of a project.
