This commit improves performance by optimizing rule loading. Built-in rule imports are now cached, ensuring each rule module is only imported once across all files. Additionally, rules are loaded in parallel using Promise.all() instead of sequentially. The rules index is also simplified from just under 450 lines of repetitive getter definitions to around 180 lines using a declarative array and dynamically generating getters.

Compared to the performance of #9021 (by applying these changes on top of the ones from that PR), using the benchmark tool from #9020:

Mode Workspace size Before After Change Status
API Small 40.57ms 52.33ms +29.0% ✗ Slower
Medium 302.43ms 274.43ms -9.3% ≈ Same
Large 2.13s 1.73s -18.6% ✓ Faster
X-Large 7.71s 6.47s -16.1% ✓ Faster
CLI Small 471.80ms 456.10ms -3.3% ≈ Same
Medium 829.15ms 769.28ms -7.2% ≈ Same
Large 2.92s 2.54s -12.9% ✓ Faster
X-Large 9.36s 7.88s -15.8% ✓ Faster

The small API benchmark shows a small 12ms increase in runtime, presumably because the overhead of parallel loading is significant relative to the short baseline time. However, this is a negligible increase that won't be felt by users when linting, and is offset by substantial gains at scale where the parallel loading and caching compound. This increase in time is not observed when testing using the CLI against the same size workspace.

It fixes 7 bugs, including 5 performance ones that make Stylelint 7x faster and use 3x less memory on larger codebases such as design systems and monorepos. We also restructured our docs to create a [contributor guide](CONTRIBUTING.md). If you'd like to help out and contribute to Stylelint, that's the place to start.
