docs: purge the retired workstation from the knowledge base

Second half of the purge (the first covered the persona, AGENTS.md, README.md,
and the distillation of the per-host pages). Every remaining identifier is
gone: hostname, both LAN addresses, and the Wi-Fi SSID.

34 count-checked substitutions across 22 files — indexes, tool/research pages,
the inventory census, the changelog, one generated HTML report, and five
managed skills. Facts kept, names dropped: a history entry keeps its four-page
listing as a nameless summary, the syslog excerpts keep every timestamp and
line, and the census keeps the .zcompdump rows (the zsh version stamps are the
useful part, the hostname was not).

Deliberately unchanged: install.sh's --host case list and the
packages/<hostname>.pkgs filename, where the hostname is the lookup key.

Left out of scope by Frank's call: agent/memories/** — past-session records the
learn pipeline rewrites.

kb-lint: 0 violations. Residual grep for the hostname, its two IPs, and the
SSID across omp-docs/ and agent/managed-skills/: no hits.

+Both the workstation and blankpad run the bare `noctalia` v5 binary as the desktop shell (launch: niri `spawn-at-startup "noctalia"`). The old Quickshell-hosted v4 architecture (`qs -c noctalia-shell`, JSON config) is retired on both hosts. Live config layer = TOML only:
 - Hand-edit declarative layer: `~/.config/noctalia/<name>.toml` (e.g. `config.toml`).
 - Runtime state file `~/.local/state/noctalia/settings.toml` loads LAST and overrides declarative values for the same keys — never hand-edit it; UI/IPC writes land there.
