ruby_llm-browser v0.2.0

[0.2.0] - 2026-10-19

Added

• RubyLLM::Browser.tools(context:, schema:) builds fresh Inspect and Extract
  instances for chat.with_tools(*tools). It never includes Act or dispatches work.
• Agent validation commands, an offline development workbench, and desktop/mobile
  Chrome workflows with fixture screenshots. Browser libraries are development-only.

Changed

• Doctor reports mode: :offline, :live, or :unconfigured. FakeBackend checks
  skip Stagehand SDK and provider environment checks. Custom backends no longer
  receive unrelated Stagehand credential warnings. Stagehand remains blocked.
