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

Image

  • Image()

Validates if the file is a valid image by checking its MIME type.

v::image()->assert('/path/to/image.gif');
// Validation passes successfully

v::image()->assert('/path/to/image.jpg');
// Validation passes successfully

v::image()->assert('/path/to/image.png');
// Validation passes successfully

All the validations above must return false if the input is not a valid file or of the MIME doesn't match with the file extension.

This validator relies on fileinfo PHP extension.
