chore: npm release readiness (compiled dist, manifest, LICENSE, README)

- Build to dist/ via bun build (externals stay external); exports point
  at dist/index.js so installed consumers never resolve .ts sources.
- Move @opencode/plugin to dependencies (imported at runtime).
- Add LICENSE (MIT), keywords, repository, homepage, author.
- prepublishOnly runs typecheck + tests + build.
- Rewrite README usage-first: problem, install, verify, config, dev.
