v0.5.0

What's changed

Added

• DeepSeek vendor (--vendor deepseek): fetches credit balance from
  GET /user/balance, preferring USD over CNY when both currencies are
  present. Severity thresholds are scaled per currency (CNY ≈ 7× USD).
  API key is read from DEEPSEEK_API_KEY env var or [deepseek] api_key
  in config. Disabled by default (requires explicit opt-in).
• DeepSeek API key field added to the TUI Settings overlay (s key),
  consistent with Z.AI and OpenRouter.
• macOS Keychain fallback for Anthropic credentials. Recent Claude
  Code builds on macOS store their OAuth state in the login Keychain
  (generic-password service Claude Code-credentials) instead of
  ~/.claude/.credentials.json, so the widget failed with an I/O error
  on a missing file. When the file is absent on macOS, ai-usagebar now
  reads the same { claudeAiOauth, mcpOAuth } JSON from the Keychain
  via security(1), and writes refreshed tokens back to that same item
  so it keeps a single source of truth with Claude Code instead of
  forking a stale copy. Linux behavior is unchanged.
