Summary

Replaces the three-line placeholder README with a standard npm-CLI README, so the package page on npmjs.com is presentable.

• Fixes the install URL — was curl -fsSL https://dial.up.railway.app/install | bash (a Railway preview host); now https://getdial.ai/install (verified 200).
• Drops the internal reference to docs/superpowers/specs/... — not relevant to package consumers.
• Adds the usual sections: intro, installation (npm + bootstrap), quick start, a commands table, configuration/env vars, "use from an AI agent" (the skill install), a docs link, and license.
• All doc links verified to resolve (200): the CLI reference, listen service, and CLI Skill pages.

Docs-only change (no src/ or package.json edit), so no version bump is required.

Test plan

• README renders cleanly on GitHub and the npm package page
• All links resolve
