0.8.3

Agent setup

• The package ships an optional agent playbook, docs/playbook.md. It describes one setup that
  works: role notes, a shared Dispatching procedure, headless workers, the agent limit and the
  review loop. Recursive Board works the same without it.
• wi setup ends with the playbook's recommended setup, the path of the installed playbook, and
  wi doctor. An agent that runs setup shows that summary to the user, and says that it is
  optional. Setup copies no role note and writes no AGENTS.md.
• The skill tells agents to update with wi update, and to run wi update --dry-run first.

Added

• wi setup prints the optional recommended agent setup after the vault choice. --yes prints
  it too. wi setup --json --vault <path> prints one object with a recommendedSetup field.
• wi doctor checks the install and the optional agent setup on request. Each check prints pass,
  note or fix, and a fix prints the text to paste from the playbook. It writes nothing, and it
  exits 1 only when the install is broken.
• wi update installs the newest package, then refreshes both skill copies and the default
  vault's plugin files from it. It prints the Agent setup changes since the old version.
  --dry-run writes nothing.
• The npm package ships the plugin build: dist/main.js, dist/manifest.json and
  dist/styles.css.

Changed

• A card whose holder is the reserved value agent now reads Agent, not "Any agent".
