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

Not

  • Not(Validator $validator)

Negates any validator.

v::not(v::ip())->assert('foo');
// Validation passes successfully

In the sample above, validator returns true because 'foo' isn't an IP Address.

You can negate complex, grouped or chained validators as well:

v::not(v::intVal()->positive())->assert(-1.5);
// Validation passes successfully

Each other validation has custom messages for negated validators.
