OpenSquilla 0.3.1 maintenance release

🦐 OpenSquilla 0.3.1 is a maintenance release for the 0.3 line — focused on the small things that catch you off guard day to day.

💬 Chat & messaging: WebChat preserves multiline messages and improves spacing; Slack setup and reply workflows keep critical context like Socket Mode config and thread metadata.

🎬 Media workflows: voice, audio, and media helper handoffs are more reliable, and Windows scripts pause safely for review of generated output.

🧪 Provider validation: malformed tool-call history is caught locally before it reaches a provider, so bad requests do not waste tokens.

⚙️ Maintenance & CI: dependencies refreshed, CI classifies file changes by impact to skip unnecessary checks. Backward compatible with existing config.toml and session data.

Upgrade with the standard install commands — see the homepage Quickstart for the latest pinned wheel URL.
