v0.2.0

Zero-friction install

curl -fsSL https://stephens.page/vaulted-agent/install.sh | bash
va claude
va codex
va grok

What is new

1. Auto-detect agents — if claude / codex / grok are on PATH, live harnesses are written (plainfile + empty.env so launch works before vault wiring).
2. Vault setup — interactive backend choice during install (TTY), or vaulted-agent setup later. Non-interactive: --backend onepassword --op-token-file ./token.
3. No token on disk — va claude --prompt-auth (or -p) prompts for the vault token for this launch only.

Skip auto-detect: --no-auto-harness. Skip prompts: --no-setup / -y.
