added nixd lsp to helix

DEV_ENV

@@ -0,0 +1,65 @@
+This file will document what features I believe I need
+for NixOS to be a good development environment.
+
+
+Issues I've encountered:
+- [X] Audio not working
+- [ ] Tesseract is a pain in the ass to setup on Nix
+- [ ] ags no longer supports `-t` flag, so applauncher won't work, requires switching to Astral
+- [ ] script to enable/disable passwordless sudo
+
+- [ ] Move Emile.Vault to new vault (I lost the password...)
+
+- [ ] Add a simple and ugly bar
+
+- [ ] Install powertop (funny name) for monitoring power usage by processes 
+- [ ] Try to make my battery life bettery
+
+- [ ] Apply for JetBrains student license
+- [ ] JetBrains Rider and VSCodium for C#
+2. Imperative development environment behind NixOS (declarative),
+similar to python's virtualenv but for the entirety of my system.
+
+- [ ] Call my wishlist command "subspace (highway)" (Scott Pilgrim reference)
+
+- [ ] Create a GitHub profile readme like this persons:
+	  https://github.com/yuyudhn
+- [ ] Set a new GitHub profile picture (like github:@Vendicated)
+		artists credit: https://dotpict.net/users/1598051
+- [ ] Change GitHub location to /dev/zero, /dev/null, www, World Wide Web, etc
+- [ ] Clean up my GitHub profile (only have things I'm proud of)
+
+- [X] Put a template website on my VPS
+- [ ] Put a neoweb-esque webiste on my VPS
+- [ ] Host a blog on my VPS
+
+- [ ] Clean laptop and PC, there's tons of unnecessary files and documents now
+- [ ] Clean nixdots repo, start modularising it ^_^
+- [ ] Disable `allowUnfree` in nixdots everywhere, if a program needs it then they
+		can `mkForce` override it 
+
+- [X] Add LSP for Nix in helix
+- [ ] Make a way for me to put my laptop in a low power state, doing very specific actions like:
+		1. disabling LSP use by default temporarily
+
+TODO:
+- [X] make btop theming declarative
+- [ ] Merge laptop and PC dotfiles repos
+
+
+Cool Technologies:
+- wishlist (by charmbracelet)
+- Vaultwarden server + Keyguard client
+- devbox
+
+
+
+Random Idea List:
+- [ ] powertop is cool but it's outdated and ugly, make a prettier one with charmbracelet's tui library
+		and call it powerbtm lmao
+- [ ] Blog Post: a modern alternative to the suckless philosphy, 
+		why GNU keeps failing cause their programs are amazing but
+		aren't designed for humans. suckless programs are excellent
+		too when writing shell scripts, but they suck in dev environments.
+		The solution is to gamify our code and focus on aesthetics 
+		and "ergonomics" (usability) like what CharmBracelet does
