fastRebuild removes all pages from Explorer

[sarmong]

Describe the bug

When using --fastRebuild, after updating a page, all other pages disappear from explorer.

To Reproduce

1. Create 2 markdown files.
2. Run npx quartz build --serve --fastRebuild -d ./content
3. Go to one of the files and update it
4. Wait for rebuild and go to that file in browser
5. The other page disappeared from Explorer

Expected behavior

fastRebuild correctly parses all pages to convert them to html code of Explorer

Desktop:

• Quartz Version: 4.4.0
• node Version: 20.9.0
• npm version: 10.1.0
• OS: Debian 12
• Browser firefox

never run code you don't understand, but with that in mind, hopefully this is helpful.

had a tinker with this at https://github.com/oddish3/quartz-debug/blob/v4/quartz/build.ts where i also tried to refactor it after i had fixed the issue where the files don't show afrer saving an edit when serving, if the fixed version is all one wants / more correct then i think this is it : https://gist.github.com/oddish3/7df34b109a4aa1e151f83b6f134d799d

but also a headsup i know very little about this but had some time to look at this with claude, here is our conversation : https://gist.github.com/oddish3/317f1f08ab929de0c591768a5607fc9d

yeah fastRebuild doesn't really work at all, I was looking into incremental build the other day, probably have to rewrite a lot of the logics (the original author just ghosted us :( )
