Add tag filtering support for event replay

[nick-potts]

Added the ability to filter event replay by tags. This allows replaying only specific types of events based on their tags.

Changes include:

• New Tag attribute for marking event handlers with one or more tags
• Added --tag option to verbs:replay command
• Tags are case-insensitive
• Enabled prefixing for handle methods

Example usage:

// Single tag
#[Tag('email')]
public function handleSendEmail() { ... }

// Multiple tags
#[Tag(['billing', 'important'])] 
public function handleProcessBilling() { ... }

CLI usage:
verbs:replay --tag=email
verbs:replay --tag=email --tag=billing
