Add blankpad-host auto-learn skills and memory store

Tracked the harness artifacts accumulated on blankpad (blank@), matching
the existing convention for the --home-dank-* memory stores and the 36
already-tracked managed-skills.

managed-skills (9): authentik-proxy-provider-app-link,
dankclaw-guard-chain-layer-diagnosis, e2e-arr-rawip-reachability-triage,
halogen-kv-pool-fit, lan-client-split-dns-fix, noctalia-reference,
rootless-quadlet-log-retrieval, ssh-key-bootstrap-no-sshpass,
swapfile-resize-safe-ordering.

memories (2 stores): --home-blank-.omp-- (dotfiles_git, handy_lifecycle,
input_permissions) and --home-blank-Projects-serverAppConfig--
(frank_large_quadlet).

Secret sweep before staging: no PEM blocks, no credential literals.
Content is fleet topology/IPs only, same class as the tracked dank stores.

+# Noctalia Desktop Environment
+
+Noctalia is a Niri-based desktop environment at `/usr/bin/noctalia`.
+
+## Config
+- Main: `~/.config/noctalia/config.toml`
+- Niri config: includes `noctalia.kdl` for display settings
+
+## IPC
+Direct `noctalia msg <command>` replaces `qs -c noctalia-shell ipc call` wrapper.
+Key commands: `panel-toggle`, `session`, `lock`, `launcher`.
+
+## App Templates
+`/usr/share/noctalia/assets/templates/` contains: gtk, ghostty, alacritty, hyprland, sway, wezterm, helix, btop, starship, qt, kde, cava, scroll, mango, umbriel, foot, emacs, kitty.
+
+## Palette
+Generate from image: `noctalia theme [image]`
+
+## Migration Checklist
+- [ ] Niri keybinds → `noctalia msg` commands
+- [ ] Alacritty → import noctalia.toml theme
+- [ ] Ghostty → `theme = noctalia`
+- [ ] GTK 3/4 → update accent palette (#b267e4 purple)
+
+## Text Antialiasing
+- **Ghostty**: `font-subpixel-render = "off"` to disable subpixel AA
+- **Alacritty**: `font.antialias = false` in `alacritty.toml`
