v0.1.1

• Claude models in Pi and OpenCode now use prompt caching. cn set both up
  on Chat Completions, where Concentrate does not cache Claude, so every turn was
  billed at the full input price. Both now use the Responses API, as in
  Concentrate's Pi guide. Installing this version fixes cn pi, cn opencode,
  and tools set up with cn configure.
• cn claude keeps Claude's prompt cache warm between launches. Without a
  ~/.claude.json of your own, each launch looked like a new device, so resumed
  sessions re-sent the whole prompt at the cache-write price.
• Pi keeps your MCP servers, extensions, and other settings under cn pi.
• Pi and OpenCode show cost estimates with Concentrate prices.
• cn configure stores the key in Pi and Codex directly, fixing Pi's
  intermittent credential-helper errors. Installing this version converts tools
  you set up with 0.1.0 for you.
• New cn update, cn refresh, and cn changelog. cn offers new versions
  when you start it, and installing refreshes the tools you configured.
• cn logout also removes the key copies in configured tools.
