[Request] Please assist in, or add the option to, try to base on top of Firefox Nightly

There might be use cases where Firefox Nightly excels higher than stable in performance, security and privacy, as the newest freshest code lands there first, and stability is often reasonable and crashing is infrequent (I say from multiple years of using Nightly).

An example of fresh code that empowers privacy is the new Cookie Banner Reduction which could function as a nice fallback to automatically refuse cookie banners that are either manually allowed to unblock a website or that escape uBlock's Annoyances filter.

Please consider any of the following in order of effort to implement:

- Simply giving any advice/'dumbcumentation' on how to (dirtily) alter cachybrowser PKGBUILD to target the Nightly source code
- Adding "cachybrowser-git" to AUR ('dirty' port of the regular Cachy Browser PKGBUILD)
- || but as a PKGBUILD accessible through the cachyos repos if interested in 'adopting' the experimental 'you try it' PKGBUILD
- Go the extra mile and involve yourselves in any meaningful capacity if the opportunity and maintainer time/funds arrive for investigating this, such as offering a prebuilt cachybrowser-nightly

Ideally I'd do this myself as Ive done my fair share of PKGBUILD 'hacking' but I felt a smidge intimidated by this PKGBUILD and the fact I have no idea if I could reasonably compile Firefox everyday.

Thank you for reading and thank you kindly CachyOS devs for the awesome OS and apps.

Start by reviewing the existing Cachy Browser PKGBUILD and the repository's packaging conventions. The issue offers several possible outcomes—Nightly build instructions, an AUR package, a CachyOS package, or a prebuilt browser—so the desired scope and acceptance criteria need to be chosen before implementation.
