refactor(workflow-protocol): require AgentFn Opt generic

Make AgentFn<Opt> always take a mandatory options argument, removing
the void conditional overload. Simplify createAgentAdapter, restore
exports needed by tests, and fix CLI test bundles to use cas.put
instead of disallowed @uncaged/* imports.

+
+Every env var in a bundle must have a sensible default — bundles must run without any env vars set. Use \`env(name, fallback)\` from \`@uncaged/workflow-util\`.
+
+Discover the correct CLI path yourself (e.g. \`which cursor-agent\`, \`which hermes\`) and hardcode it as the fallback:

 ### Bundle import restrictions
 
 The bundle validator only allows these import specifiers:
 - Node built-ins (\`node:fs\`, \`node:path\`, etc.)
-- \`@uncaged/workflow-*\` packages
 
-Third-party packages (**including zod**) must be bundled into the \`.esm.js\` file, not left as external imports. When using \`bun build\`, only mark \`@uncaged/*\` as external.
+All other dependencies — including \`@uncaged/workflow-*\` packages, zod, and any third-party code — must be bundled into the \`.esm.js\` file. Bundles are fully self-contained: same Node/Bun version = same behavior.
