feat: Add silent option to checkHotkey to suppress console output

[solssak]

🎯 Changes

This PR adds a silent option to the checkHotkey() function to suppress console output in production environments.
Motivation:
Currently, checkHotkey() always logs validation warnings and errors to the console with no way to suppress them. This can clutter production logs, and developers have no control over this behavior.
What changed:

• Added optional options parameter to checkHotkey() with a silent boolean property
• When silent: true, console.warn() and console.error() calls are suppressed
• Updated JSDoc documentation with usage examples
• Added 3 comprehensive tests to verify the silent option works correctly
  API Example:
  // Before (still works - backward compatible)
  checkHotkey(Alt+C) // Logs to console
  // New option
  checkHotkey(Alt+C, { silent: true }) // No console output
  Testing:
• ✅ All 161 tests pass (including 3 new tests for silent option)
• ✅ Type checking passes
• ✅ Fully backward compatible (no breaking changes)
