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.

+Current state: OMP harness at ~/.omp, serverAppConfig cloned to ~/Projects (HTTP/dank token, head 701ab14). Git workflow relies on state inspection, USR1 ghostty reloads, and LFS lock mitigation. Handy runs as persistent hub daemon (69 models). Input permissions fixed for user 'blank' (root:input group, 660 perms). Dotfiles shifted to noctalia theme with Ghostty font-hinting adjustment. Reference consolidated details for repo structure, commit patterns, and CLI sudo/PTY pitfalls.
