Pull request overview

This PR fixes the Vapor compiler to properly camelize kebab-case component event handlers, aligning its behavior with the standard Vue compiler. Previously, kebab-case event names like @update-model were incorrectly kept as "onUpdate-model" instead of being converted to onUpdateModel.

Key Changes:

• Apply camelize transformation to static event handler keys before converting them to handler format
• Update existing test expectations to reflect the corrected behavior
• Add new test case specifically for kebab-case event handler camelization
