Subject: feat(remote-dev): add Nix Home-Manager flake for Ubuntu 22 VM dev env

New remote-dev/ subdir with a Home-Manager flake that provisions a
headless dev environment on a remote Ubuntu 22.04 VM accessed via SSH.
Shares nvim, zellij, zsh, direnv, and ghostty configs from the same
dotfiles repo via mkOutOfStoreSymlink (no rebuilds on config edits).

CLI tool set mirrors the dev-tool subset of meta/base.txt; sysadmin
tools (procs, gdu, duf), lazygit, and node/yarn (only needed for
markdown-preview on GUI hosts) are excluded.

bootstrap.sh is one-shot: installs Nix via Determinate Systems
installer, clones the repo to ~/.local/share/dotfiles, runs
home-manager switch, and chshes to the nix-store zsh.

dot_config/zsh/dot_zshrc loses its hardcoded Arch plugin/git-prompt
paths in favour of a fallback search: Arch path first, then
$HOME/.nix-profile/share/. Same file works on host and VM.

.chezmoiignore: exclude remote-dev/ from chezmoi deploy on the host.
