 Enhance LintSpdxCommand with contributor tracking and header normalization 
Improves SPDX header linting to ensure consistent license metadata across
the codebase.

Key changes:

- Enforce deterministic tag ordering (License-Identifier, FileCopyrightText,
  FileContributor) to ensure consistency, prevent merge conflicts, and
  simplify code reviews

- Add contributor alias mapping to consolidate contributors with multiple
  emails or name variations (e.g., "nickl-" → "Nick Lombard")

- Add --contributions-strategy option with "blame" (current code authors)
  and "log" (all historical contributors) to support different attribution
  philosophies

- Add optional path argument to lint specific files or directories

- Add --fix option to automatically correct header issues

After

  • After(callable $callable, Validator $validator)

Validates the input after applying a [callable][] to it.

v::after(str_split(...), v::arrayType()->lengthEquals(5))->assert('world');
// Validation passes successfully

Consider the following variable:

$url = 'http://www.google.com/search?q=respect.github.com';

To validate every part of this URL we could use the native parse_url function to break its parts:

$parts = parse_url($url);

This function returns an array containing scheme, host, path and query. We can validate them this way:

v::arrayVal()
    ->key('scheme', v::startsWith('http'))
    ->key('host', v::domain())
    ->key('path', v::stringType())
    ->key('query', v::notBlank());

Using v::call() you can do this in a single chain:

v::after(
    'parse_url',
     v::arrayVal()
        ->key('scheme', v::startsWith('http'))
        ->key('host',   v::domain())
        ->key('path',   v::stringType())
        ->key('query',  v::notBlank())
)->assert($url);
// Validation passes successfully

After does not handle possible errors (type mismatches). If you need to ensure that your callback is of a certain type, use Circuit or handle it using a closure:

v::after('strtolower', v::equals('ABC'))->assert(123);
// 𝙭 strtolower(): Argument #1 ($string) must be of type string, int given

v::circuit(v::stringType(), v::after('strtolower', v::equals('abc')))->assert(123);
// → 123 must be a string

v::circuit(v::stringType(), v::after('strtolower', v::equals('abc')))->assert('ABC');
// Validation passes successfully
