docs: fix broken links and editor references in readmes

- root README: VS Code config moved from home/linux/gui/base/editors.nix to vscode.nix
- READMEs now list both GUI editors (Zed, the primary one, plus VS Code)
- base README: xdg is a directory now, nvidia.nix no longer exists, editors.nix -> vscode.nix
- idols-ai README: disko-fs-media.nix -> disko-fs-data.nix (/persistent/data)
- secrets README: password-store moved from home/base/desktop to home/base/tui
- drop unused link definitions (AstroNvim, wl-clipboard, Catppuccin)
- fix a pre-existing typo flagged by the typos hook (keeped -> kept)
