Improve installation experience by adding Ainte to package managers

**Is your feature request related to a problem? Please describe.**
Currently, people are able to set up Ainte only installing jq, bun, nodejs on their own and then running it.
It makes the lifes of testers worse, compared to just installing it using a package manager.

**Describe the solution you'd like**
We should add the tool to brew and apt so that people can install it easily.

**Describe alternatives you've considered**
If adding it to package managers is difficult then we should bundle it into a simple makefile that installs the needed tools.

Start by auditing the repository's existing installation and build configuration, since the issue names no files or entry points. Review how jq, bun, and nodejs are currently required, then investigate the packaging requirements for Homebrew and apt. Done means users can install Ainte through both requested package managers without setting up those tools manually.
