perf: Switch Whisper to tiny.en (10x faster), increase proxy+uvicorn timeouts to 120s for CPU inference

fix: Lightweight baseline extraction — only compute pitch/energy/tempo inline, skip full feature pipeline to prevent OOM on HF

fix: Graceful fallback for baseline audio processing

fix: Restore full requirements.txt with CPU-only PyTorch for HF deployment

fix: Use lightweight requirements-deploy.txt (no PyTorch/transformers/whisper) to fit HF free tier size limits — ML services already have graceful fallbacks

fix: Type conversion errors for TrustedMember UUID and created_at column fetching

feat: Add Trusted Circle management UI in settings

feat: Broadcast Weekly Report to Trusted Circle via Brevo endpoint and UI button

style: Remove accept invitation button from Brevo email and change copy to reflect automatic enrollment

fix: Hardcode Brevo sender fallback to development email to bypass missing .env configurations

fix: Allow configuring Sender Email for Brevo via BREVO_SENDER_EMAIL to prevent silent drops on non-verified domains

fix: Only save trusted circle member to DB if Brevo email sends successfully

feat: Connect Trusted Circle invites to real Brevo transactional email sender

feat: Context-aware journal prompts, sleep correlation tracker, and dark/light mode toggle

feat: Weekly Report — Spotify Wrapped-style emotional summary with mood arc, AI narrative, emotion breakdown, and one-click image export

InnerVoice Production Upgrade: Multi-channel chat, premium UI components, Whisper-small accuracy upgrade, and full-screen layout polishing

feat: preload AI models on backend startup to reduce latency

feat: implement JWT auth and voice calibration onboarding
