Allow Trailing Commas in repomix.config.json

[rockmandash]

When working with the "includes" key, I often comment out file paths to quickly test or calculate final token counts. However, I have to manually remove the trailing comma every time. Since comments are already supported in repomix.config.json, it would be very helpful if trailing commas were supported as well.

For reference, you can see where this is handled in our code:

repomix/src/config/configLoad.ts

Line 70 in b55c59d

const config = JSON.parse(stripJsonComments(fileContent));

Additionally, the json5 library, which we could consider as an alternative, supports trailing commas.

Or maybe we should support repomix.config.js javascript format? This way I can even inline instruction.md file using tagged template literal, no need separate files.

Hi, @rockmandash !
Thank you for the suggestion!

Yes, parsing with json5 sounds like a good solution for the trailing comma issue.

Regarding the js/ts config file support - I've been considering this for a while but haven't implemented it yet due to complexity concerns. I know there's demand for it, so I'll keep it under consideration for future updates.
