Vendor Bird's Twitter GraphQL search client directly into /last30days, eliminating the dependency on `npm install -g @steipete/bird`. X search now works out of the box with just Node.js 22+ and browser cookies. - Add vendored bird-search.mjs wrapper (search-only subset of Bird v0.8.0) - Vendor @steipete/sweet-cookie for browser cookie extraction - Update bird_x.py to call vendored Node.js module instead of `bird` binary - Update README.md and SKILL.md for v2.1 (remove Bird CLI install steps) - Include Bird's MIT LICENSE in vendor directory The fallback chain is: vendored search -> xAI API key -> web-only mode.
