Add a script in aci-mcp to easily install our MCP servers in Cursor, Claude desktop, etc

### Required Pre-requisites

- [x] I have read the [Documentation](https://www.aci.dev/docs)
- [x] I have searched the [Issue Tracker](https://github.com/aipotheosis-labs/aci/issues) and [Discussions](https://github.com/aipotheosis-labs/aci/discussions) that this hasn't been reported yet.
- [x] Consider asking in [Discussions](https://github.com/aipotheosis-labs/aci/discussions) first

### Motivation

Right now if users want to use our MCP server, they have to edit the JSON configs for each client (Cursor, Claude, etc), which can be tedious, especially the users will also need to replace the API key place holder with their actual API key.

### Proposed Solution

Many MCP servers today just provides a convenient command that can be run on the terminal to install those MCP server. We should do the same.
