docs: purge the retired workstation from auto-learned memory and the backup snapshot

Finishes the purge. These two surfaces were left out of the earlier commit
because the memory store is auto-generated, but both are read back into every
future session, so the name was still reaching the agent.

58 sites across 16 files: hostname, both LAN addresses, the SSID. Special-cased
the compound names a blind token swap breaks ('dank@the workstation/dankclaw',
'on the workstation/Dankclaw/Dankserver') and reworded the four that came out
ungrammatical. Facts kept: the hardware inventory of the box, the noctalia
architecture history, and today's own purge lessons all survive intact — only
the identifiers are gone.

Non-memory: the tracked .pre-pull-backup snapshot of a managed skill, whose
live counterpart was already clean.

-Repository /home/dank/.omp: develop has stashes, main synced with origin. Uncommitted: modified AGENTS.md, config/models, deleted skills. Desktop unification complete: dankware & blankpad run bare noctalia v5 native via live runtime flip. Lock uses D-Bus msg without WAYLAND_DISPLAY pinning. Keybinds use verified v5 verbs. Config reload via kill -USR1. v5 uses TOML-only (legacy v4 JSONs inert). Commit 961de3b local on dankware; rsync deploy to blankpad verified.
