Title Case ConverterConvert text to Title Case with proper capitalization rules.

Title case conversion capitalizes the first letter of each word while keeping certain minor words lowercase. The algorithm first splits text into words, then applies capitalization rules: always capitalize the first and last word, capitalize all major words (4+ letters), and lowercase minor words (articles: a, an, the; prepositions: in, on, at, by, to, etc.; conjunctions: and, but, or, nor, for, yet, so). After colons or semicolons, the next word is always capitalized. Hyphenated words have each part capitalized (e.g., "self-aware" → "Self-Aware"). The implementation handles edge cases like all-caps input (first lowercased, then title-cased) and preserves intentional uppercase like acronyms when possible.
