What is new in OpenQuack 2.0.0-alpha.22

## What's new

- 🎛️ **Editable polish system prompt** (#108, SPEC-007) — tune how the on-device LLM cleans up your dictation (CJK/Latin spacing, ASR mishears) right from Settings, with a reset-to-default button. Also fixes a crash the feature exposed: long custom prompts no longer abort the llama.cpp prefill.
- 🪟 **Recording overlay follows you** (#102, SPEC-004) — the overlay now surfaces onto whichever Space/desktop you're actually on, instead of staying behind.
- 📋 **History cap applies at launch** (#106, SPEC-014) — your saved history entry limit now takes effect immediately on app start, not just after it's re-saved.
