v0.2.1 — notarized + cost tracking

Notarized release. brew upgrade --cask callcapture (or fresh install below).

brew tap bodharma/callcapture
brew install --cask callcapture

What's new

• 🔏 Fully notarized by Apple (Gatekeeper-clean double-click; no quarantine workaround needed).
• 💵 Per-session cost tracking — transcription + LLM processing cost shown per session, with editable rates in Settings → Pricing.

Self-contained: bundles the Python worker; uses cloud transcription (AssemblyAI / Deepgram) + on-device diarization, sentiment, emotion, insights. On-device Whisper is source-build only for now.
