Add per-rule enabled config

[krekas]

Every FilaCheck rule can now be individually enabled or disabled via a published config file.

config/filacheck.php (new file)

A new config file is introduced with an enabled key for each of the 16 rules, all defaulting to true.

src/FilacheckServiceProvider.php

The service provider now loads and publishes the config, then filters the rule list before registering. Disabled rules are never passed to the scanner, so they are skipped entirely — not just silenced.

New behaviour

To disable a rule, publish the config and set enabled to false:

php artisan vendor:publish --tag=filacheck-config

// config/filacheck.php
'deprecated-reactive' => [
    'enabled' => false,
],

• Rules default to enabled: true, so existing installations are unaffected.
• Disabling a rule removes it from the registry entirely — it won't appear in output or count toward any totals.
• No changes were made to individual rule classes.
