Add apply_to_files and skip_files parameter to rules and config

[jeparlefrancais]

Closes #7

These changes add a per-rule file filtering to control which files are processed by a rule.

• apply_to_files: only files whose path matches at least one pattern are processed
• skip_files: files matching any of the provided patterns are skipped. This is applied after apply_to_files, so both can be combined (e.g. only src/**/*.luau but skip **/*.test.luau).

Both fields are also added as parameters to the configuration, and they control if all the rules are applied or not.

Rule Example

"rules": [
  {
    "rule": "rename_variables",
    "apply_to_files": ["src/**/*.luau"],
    "include_functions": false
  }
]
