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.
