v1.4.0

Added

• GitHub Copilot usage tracking and quota support (#19) — CopilotParser for OTEL JSONL files (Copilot CLI and VS Code Copilot Chat), Copilot quota API query via GitHub OAuth token, auto-discovery of ~/.copilot/otel/*.jsonl and $COPILOT_OTEL_FILE_EXPORTER_PATH
• KiloCode parser support (#20) — parser for KiloCode VS Code extension SQLite database (kilo.db), supports input/output/cache/thinking tokens and cost calculation
• Per-model token breakdown with stacked bar visualization (#21) — API exposes inputTokens, outputTokens, cacheReadTokens, cacheWriteTokens, thinkingTokens, totalCost per model; unified ranked list with stacked composition bars
• Auto-detect tools and expand from 8 to 22 (#22) — automatic detection of installed AI tools replaces manual source path configuration; read-only Detected Tools panel in settings UI; GET /api/detected-tools endpoint
• USD/CNY currency toggle (#17) — segmented toggle in Pricing page to switch between USD and CNY display with exchange rate conversion
• Expanded model pricing table — added OpenRouter, Google, and additional Claude/OpenAI model variants; new inputText pricing field for models with separate text input pricing

Fixed

• Auto-recalculate costs after pricing save/reset (#15) — server automatically recalculates all record costs after save/reset, removing the need for manual recalculation; fix edit form layout for Chinese labels
• Fallback to credential file when keychain data is unusable (#18) — falls through to file-based credentials when macOS Keychain entry is not usable (parse error, wrong auth_mode)
