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

When

  • When(Validator $when, Validator $then)
  • When(Validator $when, Validator $then, Validator $else)

A ternary validator that accepts three parameters.

When the $if validates, returns validation for $then. When the $if doesn't validate, returns validation for $else, if defined.

v::when(v::intVal(), v::positive(), v::notBlank())->assert(1);
// Validation passes successfully

v::when(v::intVal(), v::positive(), v::notBlank())->assert('non-blank string');
// Validation passes successfully

v::when(v::intVal(), v::positive(), v::notBlank())->assert(-1);
// → -1 must be a positive number

v::when(v::intVal(), v::positive(), v::notBlank())->assert('');
// → "" must not be blank

In the sample above, if $input is an integer, then it must be positive. If $input is not an integer, then it must not be blank. When $else is not defined use AlwaysInvalid
