Tracking issue for CI overhaul

[WolfSkin0]

This is the tracking issue for the CI overhaul.
Currently CI is in a horrible state with a bunch of non-functional code, an outdated build system, and an absolute mess of files.
Below are the current identified components and change proposals.

Workflow Components

Tool Installation

• Node.js
• Python
• SpacemanDMM's dreamchecker
• [NEW] Rustup & Rust
• [NEW] OpenDream (for additional linting)

Linter Tasks

• Ensure Directories are not "ticked"
• Generate changelogs
• Grep-based spellcheck (Need to double-check the code, but it looks like that's what it does)
• Check PHP and JSON file syntaxes
• Some script that I guess checks ticked files against schemas
• Run tgui tests
• Check if every DMI file can be parsed
• Check if every DMM file can be parsed
• Run spacemandmm's dreamchecker on the map

Potential Changes to Make

• Switch python to using Rye (for better portability)
• Switch Nodejs to Bunjs (faster, better direct TS support)
• Ditch Juke as the build system (seems to have received no updates as of 3 years ago) -- Replace with cargo-make?
