Add NPX commands for installing and listing packages

Implement the `mcp-get` NPX command to install and list packages.

* **README.md**
  - Add instructions for using the `npx @michaellatman/mcp-get install {PACKAGE}` command
  - Add instructions for using the `npx @michaellatman/mcp-get ls/list` command

* **src/index.ts**
  - Create the main entry point for the commands
  - Import and use the `install` and `list` commands

* **src/install.ts**
  - Implement the logic for the `install` command to install a package

* **src/list.ts**
  - Implement the logic for the `ls/list` command to list installed packages

* **package.json**
  - Add a `bin` field to define the `mcp-get` command
  - Add dependencies required for the `install` and `ls/list` commands

* **packages/package-list.json**
  - Create a JSON file to contain the list of all available packages with properties: name, description, vendor, sourceUrl, and license

* **src/auto-update.ts**
  - Implement an auto-update function to update the `mcp-get` package if a new version is available
