feat(automode): autonomous coding loop with session persistence

  Add Auto-Mode - an autonomous coding loop for hands-free task completion.

  Features:
  - Autonomous iteration loop with configurable max iterations
  - Git worktree isolation for safe experimentation
  - Checkpoint system with automatic git commits
  - Circuit breaker protection (no progress, same error, test-only loops)
  - Completion promise detection (configurable keyword)
  - Resource limits (max runtime, max cost)
  - ESC key cancellation
  - Detailed changelog generation

  Session & Patterns:
  - Sessions saved to ~/.autohand/sessions/ and resumable via /resume
  - Auto-detects tech stack, frameworks, test/build/lint commands
  - Updates AGENTS.md with discovered project info

  CLI: --auto-mode, --max-iterations, --completion-promise, --no-worktree
  Slash: /automode status|pause|resume|cancel
  Hooks: automode:start|iteration|checkpoint|complete|cancel|error

-Autohand is an autonomous LLM-powered coding agent that lives in your terminal. It uses the ReAct (Reason + Act) pattern to understand your codebase, plan changes, and execute them with your approval. Built with TypeScript and Bun for blazing-fast performance.
+Autohand Code CLI is an autonomous LLM-powered coding agent that lives in your terminal. It uses the ReAct (Reason + Act) pattern to understand your codebase, plan changes, and execute them with your approval. It's blazing fast, intuitive, and extensible with a modular skill system.
+
+We built with a very minimalistic design philosophy to keep the focus on coding. Just install, run `autohand`, and start giving instructions in natural language. Autohand handles the rest.
+
+Scale Autohand across your team and CI/CD pipelines to automate repetitive coding tasks, enforce code quality, and accelerate development velocity.
