2.0.1

• Security: Moved Companies House API calls to a server-side WordPress AJAX endpoint so the API key is never exposed in frontend HTML.
• Added: Support for searching Officers and Disqualified Officers, plus a Company Officers tab inside the company profile modal.
• Fixed: Shortcode now properly uses output buffering (ob_start() / ob_get_clean()) instead of echoing directly.
• Fixed: Pagination off-by-one bug and null-safety for missing company fields.
• Improved: Scoped CSS styles under .ch_wrapper, standardized 4-character PHP prefixes (CHSP_ / chsp_), and added External Services disclosure for WordPress.org compliance.
