InputTextControl enhanement

Editor assessment

The typo 'enhanement' is the first thing reviewers will see, and it sits in an otherwise unremarkable noun-phrase subject; imperative 'Extend InputTextControl with focus and blur handlers' would fix both mood and spelling while promoting the component to a scope. The feat type is correct for new configurable event handlers and yields a minor bump. The body earns credit by saying what changed — two more event handlers for focus and blur accepted from property pane config — though it never says why (what use cases or user requests motivated them), and it repeats rather than deepens the header. Formatting is compliant: blank line before body, well-formed Co-authored-by trailer, no trailing period. No breaking-change concerns since the new handlers are opt-in configuration. Decent content undermined by a careless header.
