* docs: Ralph report scaffolding + pureintent eval baseline (10.87s) * cycle-1: drop nixvim — pureintent eval 10.87s → 6.98s (-36%) nixvim's home-manager module system is by far the dominant cost of evaluating `nixosConfigurations.pureintent`: a profile of selective imports puts it at 3.97s of the 10.87s baseline (~36%). Replace it with a minimal `programs.neovim.enable = true` configuration. The runtime behaviour of `nvim` changes (no plugins, no LSP, no mapleader/telescope/treesitter/etc.) — accepted by the user. Measured on srid-nc (nixos, 6.12.85 kernel), 7 warm-cache runs with `--option eval-cache false`: baseline: 10.85 10.86 10.86 10.87 10.87 10.88 10.91 -> median 10.87s cycle-1: 6.94 6.96 6.98 6.98 7.02 7.02 7.73 -> median 6.98s Other configurations still evaluate: - nixosConfigurations.naiveintent - darwinConfigurations.infinitude-macos - homeConfigurations."srid@zest" Removes flake input `nixvim` (+ its `flake-parts`, `nixpkgs`, `systems` sub-inputs from the lock). * docs: wrap up Ralph report (10.87s -> 6.99s = -35.7%) 7 dead-ends documented so they don't have to be re-tried. Key finding: after dropping nixvim (cycle 1), the eval floor is home-manager's per-entry submodule materialisation (systemd.user.services / programs.ssh.matchBlocks), not the option-declaration count of any wrapper module. Inlining jumphost-nix or vira moves the cost; it does not eliminate it.
