cotel v0.2.0

Added

• Multi-user telemetry separation — each Claude Code user's data is tracked independently via user.id resource attribute
• Bearer-token authentication: API token creation and management via Tokens page; tokens linked to users in OTLP ingest
• Users page with search, pagination, per-user click-through to filtered analytics, and anonymous user view/delete
• Unified analytics dashboard with per-user filter across all charts and tables
• Setup page with step-by-step onboarding guide and copyable agent configuration prompt
• History page with time-series charts and daily activity heatmaps
• Session Detail: Cache Read and Cache Write KPI cards
• Data export (versioned ZIP/CSV) and import endpoint (POST /api/v1/import) with migration support
• Export/import round-trip integration tests
• Public ingest URL configuration (COTEL_PUBLIC_INGEST_URL) surfaced on Setup page
• Cloudflare Tunnel integration: locally-managed mode with bundled cloudflared binary
• Allow-anonymous setting to accept unauthenticated telemetry
• cotel logo mark as SVG favicon and sidebar brand
• GitHub links in header and Setup page
• VitePress documentation site deployed to GitHub Pages
• Manual release workflow with automated CHANGELOG stamping, Docker image push to GHCR, and GitHub Release creation
• Deploy workflow for self-hosted runner on push to main

Fixed

• Sessions were always empty with Claude Code beta telemetry: corrected attribute key mismatch for tool_name and cache_creation_tokens
• Cost-by-user chart now sorted by cost descending instead of insertion order
• Dashboard costs rounded to 2 decimal places
• Export endpoint returned 401 incorrectly; shared auth middleware extracted and applied consistently
• Session navigation: use React Router instead of window.location to avoid full page reloads
• Propagate cotel exit code from entrypoint script
• GitHub→Paperclip intake: prevent duplicate issues and ensure backlog landing

Changed

• Legacy server-side rendered dashboard replaced by full React SPA served on all routes
• Settings page merged into Setup as a second tab
