[DRAFT] Cli add initial support

[chelojimenez]

Note

Low Risk
Mostly build/test scaffolding and an executable entrypoint; low risk aside from potential packaging/runtime invocation issues if dist output or module resolution differs across environments.

Overview
Introduces initial CLI package wiring by adding a bin/mcpjam.js Node shebang entrypoint that runs the built dist/index.js.

Adds CLI-local project hygiene and test infrastructure: a cli/.gitignore for node_modules/ and dist/, plus a new ESM jest.config.js using ts-jest (with coverage settings and ignored TS diagnostic codes) to enable TypeScript unit tests under cli/tests.
