Pull Request Overview

This PR adds a new CamelCase function to the sx package that converts strings and string slices to camelCase format. The function follows the existing pattern established by PascalCase but produces camelCase output (first letter lowercase).

• Implements CamelCase function with support for both string and string slice inputs
• Adds comprehensive test coverage for various input formats and edge cases
• Introduces a helper function lowercaseWord for converting the first character to lowercase

[Copilot]

Converting to PascalCase first then lowercasing introduces unnecessary work. Consider implementing camelCase directly by reusing the PascalCase logic but applying lowercaseWord to the first word only, similar to how the slice case is handled.

Suggested change

	pascalCase := PascalCase(v, opts...)
	return lowercaseWord(pascalCase)
	options := CaseConfig{}
	for _, opt := range opts {
	opt(&options)
	}
	words := splitByCaseWithCustomSeparators(v, nil)
	result := joinWords(words, "", func(word string, i int) string {
	normalized := normalizeWord(word, options.Normalize)
	if i == 0 {
	return lowercaseWord(normalized)
	}
	return capitalizeWord(normalized)
	})
	return result
