v2.1.0 — Google Antigravity, CLI and IDE

Added

• Google Antigravity, CLI and IDE. Antigravity — which Google is moving Gemini CLI
  users onto — wasn't read at all, so a heavy Antigravity user's share showed none of it.
  It keeps each conversation as an undocumented SQLite database of protobuf blobs under
  ~/.gemini/antigravity-cli/ and ~/.gemini/antigravity-ide/. The token usage per
  model call, the model, tool calls with their arguments, errors and command exit codes
  were decoded from real databases and checked against the plain-text transcripts
  Antigravity writes for some conversations (which carry no token counts themselves).
  Both Gemini and Claude models running inside Antigravity are recognised. Reading needs
  nothing beyond the standard library.
• doctor reports data it can't read. Older Antigravity versions saved encrypted
  .pb conversations; doctor now says how many it found rather than leaving a gap
  unexplained.

Fixed

• claude-opus-4-6-thinking (Antigravity's id for Opus 4.6) grouped as plain "Opus"
  instead of "Opus 4.6".
