feat: add parameters and subcommand to client.js

- Added `"commander": "^11.0.0"` as a dependency in the `package.json` file
- Added an `import { program } from 'commander'` statement in the `client.js` file
- Modified the `createdSession` function in the `client.js` file to use `program.opts().host` instead of `API_ENDPOINT`
- Added a `getSessionList` function in the `client.js` file to fetch the list of sessions
- Added a `lastSession` function in the `client.js` file to get the last session from the session list
- Added a `connect` function in the `client.js` file to establish a socket connection
- Modified the `main` function in the `client.js` file to use `program.opts().session` instead of `process.argv[2]` to get the session ID
- Modified the `main` function in the `client.js` file to use `program.opts().host` instead of `API_ENDPOINT` to initialize the socket connection
- Added a `program` object with options and actions in the `client.js` file
- Added `.bash_history` to the `.gitignore` file
- Added `.viminfo` to the `.gitignore` file
- Added `*.swp` to the `.gitignore` file
