Changelog

Unreleased

Core command set: tweet, reply, read, replies, thread, search, mentions, and whoami.
Dual transports: GraphQL (cookie-based) and Sweetistics (API key); auto engine switches to Sweetistics when a key is present.
Sweetistics features: media uploads (images or single video), 15s request timeouts, and conversation fetch with force=true so threads/replies are always fresh.
Browser credential sourcing: Firefox (--firefox-profile) and Chrome (--chrome-profile) alongside env/CLI; JSON5 configs (~/.config/bird/config.json5, ./.birdrc.json5) with allowChrome/allowFirefox toggles and engine defaults.
whoami works with both transports and prefers Sweetistics when available; colorized help banner plus example block.
CI coverage: push/PR workflow (Node 22, pnpm 10, Go stable) running pnpm test; test suite expanded (≥70% coverage).
