Add --search option to wp profile hook to filter results by callback name

[Copilot]

• Explore codebase and understand the structure
• Add --search=<pattern> option to wp profile hook command documentation
• Implement filter_by_callback() private static method in Command.php (case-insensitive substring match)
• Apply search filter in the hook() method after spotlight filtering
• Add Behat tests: search on a specific hook, search across all hooks with --all
• Refactor filter_by_callback() to use array_filter for idiomatic PHP
• Validate with linting, code style, and static analysis
