Polyphon at v0.8.0: The End of the Prototype Phase

When I shipped Polyphon v0.1.0-alpha.2, session export and a plugin system were next on the roadmap. Today it's v0.8.0, and the features that actually changed how the product feels weren't the ones I planned: voices that interact with real files with per-voice sandboxing, whole-database AES-256 encryption with password protection, and FTS5 search that turns conversation history into working memory. This is the release where Polyphon starts to feel trustworthy for real work.
