[FEATURE] Improve Out Of The Box Nature Of CachyOS + Apps In It (Optional Or Default)

### Pre-flight checklist - [x] I have searched existing issues/PRs and this has not been requested before. - [x] I have read the [Contributing Guidelines](https://github.com/CachyOS/linux-cachyos/blob/master/CONTRIBUTING.md). ### Request type - [x] New patch / patchset inclusion - [x] Kernel config change (enable/disable option) - [x] New kernel variant - [x] Scheduler tuning / addition - [x] Compiler / LTO / PGO optimization - [x] Security hardening - [x] Driver or hardware enablement - [x] Other ### Summary Two installer/defaults suggestions: 1. Ship sensible optional dependencies by default. Firefox installs without a spell-check dictionary, so spell check silently doesn't work until the user discovers hunspell-en_us exists. Nothing tells you it's missing — the feature just doesn't happen. Features users expect to work should work out of the box. Same applies to other common optional deps where the absence looks like a broken feature rather than a missing package. 2. Add a package selection step to the installer. Default to one app per job — one GUI and one terminal option for each role, matching the chosen desktop environment. Put alternatives (alacritty, micro, glances, etc.) behind an optional "extras" checkbox, off by default. Right now a KDE install ships duplicates of tools KDE already provides, which adds menu clutter for users who won't use them. This would also make the ISO smaller and cut install time. These two together would meaningfully improve the out-of-box experience — fewer surprises for new users, less cleanup for everyone else. We need something more uniform, less bad bloat, more good bloat, depend-ices, auto download depend-ices based on what you get, so maximum and stability and compat and security and such, so everything thats installed by default and any optional installed like gaming packages and more will ofc work out of the box, some people don't wanna hunt stuff down do do loads of coding or commands or anything like that, please make it easier and better by default, esp bases on what you have or pick, more up-top, please do this, thanks, good-luck:) - GG https://discordapp.com/channels/862292009423470592/1540353927071924234 ### Motivation / use case improve ease ability. stablenss compat for new users who dont wan to tweak cachy can be for anyone for anything ### Patch / upstream reference (if available) _No response_ ### Testing / benchmarks _No response_ ### Additional context _No response_
