* This fixes #315
* In .gitignore,
  - add .idea
  - remove bin/build
* Remove bin and bin/cli.js
* Remove bin/scripts/copy-cli.js
* Refactor/move bin/scripts to cli/scripts
* Refactor/move bin/src/index.ts to cli/src/cli.ts
* Refactor/renamed client/bin/cli.js to client/bin/client.js
* In .github/workflows/main.yml,
  - add run of cli tests
* In cli/pacakge.json
  - change main and bin/mcp-inspector-cli properties to build/cli.js
* In client/package.json,
  - change bin/mcp-inspector-client properties to build/start.js
* In pacakge.json
  - change bin/mcp-inspector property to ./cli/build/cli.js
