OpenSquilla 0.2.1 maintenance release

🦐 OpenSquilla 0.2.1 is here — a maintenance release focused on stability, memory quality, and Windows 10 polish.

💪 Long-running WebUI sessions: tool-heavy operations now recover more cleanly from exhausted tool budgets, repeated tool failures, large file-write attempts, and final-response degradation.

🧠 Memory recall: the semantic search system now normalizes embeddings before querying and preserves high-confidence matches, improving multilingual lookup.

📎 Artifact delivery: generated files no longer leave duplicate messages in chat history once delivered.

🪟 Windows 10 startup: the portable launcher handles Visual C++ runtime initialization more reliably.

Big thanks to @nice-code-la for the Windows 10 bootstrap fixes. Upgrade today and let us know how it feels!
