There is a new test "Deep name collision" on AllOfTest that
exemplifies the kind of collision this change solves.
Some extra `__root__` keys needed to be added to a select few
other scenarios for consistency.
This commit introduces REUSE compliance by annotating all files
with SPDX information and placing the reused licences in the
LICENSES folder.
We additionally removed the docheader tool which is made obsolete
by this change.
The main LICENSE and copyright text of the project is now not under
my personal name anymore, and it belongs to "The Respect Project
Contributors" instead.
This change restores author names to several files, giving the
appropriate attribution for contributions.
This commit resolves an issue where validation messages would overwrite
each other when multiple validators failed on the same path or key
(e.g., within an `Each` or `Key` validator).
Changes to `NestedArrayFormatter`:
- Implemented a merge strategy: Key collisions now result in a list of
messages instead of the last message winning.
- Improved handling of mixed key types: When both numeric and string
keys are present (common in composite validators), numeric keys are now
replaced by the validator's ID (e.g., `arrayType`, `equals`) to provide
meaningful, distinct keys.
- Preserved list behavior: Purely numeric key sets are treated as lists,
maintaining their sequence without re-keying logic.
- Refactored the class to use smaller, single-purpose methods and
`array_reduce` for clarity.
Tests:
- Updated feature tests (`EachTest`, `AttributesTest`, etc.) to expect the
full set of validation errors.
- Enhanced `NestedArrayFormatterTest` with scenarios for key collisions,
mixed keys, and ID substitution.
