Add cross-platform SystemSpeller abstraction with three backends: - Windows: direct COM vtable calls to ISpellChecker (Win32 Spell API), no external crate — uses the same hand-rolled FFI pattern as file_association.rs. Handles ALL-CAPS words by also testing lowercase. - macOS: NSSpellChecker via objc2/objc2-app-kit (already in deps). - Linux: Hunspell .dic file reader + hunspell CLI pipe fallback. text_audit gains three new parameters: system_spellcheck: true — activate OS spell-checker language: en-US — BCP-47 language tag (default: OS default) suggest: true — include spelling suggestions The agent dictionary and system speller work as a layered pipeline: words matching the agent dictionary are accepted immediately; only remaining words are forwarded to the OS checker. Response includes a system_speller object (enabled, available, backend, language) and an unrecognized_words array with handle, position, and optional suggestions. Integration test: text_audit_system_spellcheck_flags_misspelled_words (20/20 p1_tests pass). Release build verified.
