Minor Improvements

[Lightning11wins]

While reading some docs, I made a few minor improvements. These only improve the docs by about 5-10%, so they might not even be worth the time to review. Still, I'll leave this here in case we decide to use it at some point.

I wanted to make sure that devs using IntelliJ IDEA didn't accidentally push their editor files. I doubt most of us are using that editor, but it was an easy change to make.

This looks like fine, usable work. It's not at all a large PR, but it's still a small improvement on the pieces of documentation that it improves.

Also, looks like I forgot to label this, so that's fixed now.

Greptile Summary

This PR makes documentation-only improvements to two Markdown files (javascript.md and serverside_html_generation.md) — adding bold Author/Date headings, a Table of Contents, code-fenced syntax highlighting, and prose rewrites for clarity — plus adds .idea to .gitignore.

• The cross-reference in serverside_html_generation.md (line 16) still says javascript.txt instead of javascript.md, which is the symmetric fix of what was correctly applied in javascript.md.

Confidence Score: 4/5

Safe to merge after fixing the stale javascript.txt cross-reference in serverside_html_generation.md.

One P1 finding: the cross-reference to javascript.txt was not updated to javascript.md, breaking the intended symmetric fix. All other changes are clean documentation improvements.

centrallix-sysdoc/serverside_html_generation.md — stale cross-reference on line 16.

Important Files Changed

Filename	Overview
.gitignore	Adds *.idea/* to ignore JetBrains IDE metadata; pattern is unconventional but functionally correct for the .idea directory.
centrallix-sysdoc/javascript.md	Formatting improvements: bold Author/Date, inline code for file names, js syntax highlighting on code blocks, and minor prose rewrites for clarity. Cross-reference to serverside_html_generation.md is correctly updated.
centrallix-sysdoc/serverside_html_generation.md	Adds Table of Contents, bolds Author/Date, and adds attribution line. However, the cross-reference on line 16 still uses javascript.txt instead of javascript.md.
