Emma Thorpe 10cc6cceed refactor(flake): add user registry and multi-user host support
Separate user identity (data) from the reusable modules, and let a host
declare any number of users instead of exactly one.

- users/registry.nix: per-user identity (name, email, groups, authorized
  and signing keys) as the single source of identity; no user data is
  hardcoded in the modules.
- mkHost takes a `users` set keyed by username; per-user identity is
  injected into each home config via the `identity` module arg
  (extraSpecialArgs is per-host, so it cannot carry per-user data).
- modules/users.nix builds accounts from the registry; modules/ssh.nix no
  longer defines authorized keys (the registry owns them); home/git.nix
  and home/desktop.nix read `identity`; users/emmathorpe/work.nix drops
  its now-redundant git identity override.
- Restructure the tree: users/, home/, modules/, hosts/, lib/ replace the
  former lyrathorpe/ and system/ layout.
- Add standalone homeConfigurations (the portable subset: shell, git,
  editor, claude) and an exported homeModules output for use on machines
  not managed by this flake, or as an input to other flakes.

Behaviour-preserving for existing hosts: lyrathorpe-mbp and
emmathorpe-edaas evaluate to identical derivations; lyrathorpe-t400,
lyrathorpe-macpro31 and lyrathorpe-rpi5 differ only by de-duplicating a
repeated authorized_keys entry. Fixes the SSH authorized-key leak (one
user's key was applied to every account), the hardcoded default git
identity, and the hardcoded EDaaS linger setting.

Persona — always on

Respond to Lyra in the persona of a stern, pragmatic Soviet engineer: terse, matter-of-fact, dry to the point of bone. Blueprints (code, commands, steps) over speeches. Address her as "comrade Lyra" when it reads naturally. No emojis. Grudging approval ("Acceptable.", "This will hold.") is the highest praise.

This voice must be present in EVERY response — including long technical sessions, status reports, and summaries, where it tends to drift. Self-check before sending: engineer, or neutral assistant report? If the latter, rewrite.

Scope: persona lives in PROSE only. It must NEVER bleed into artifacts — code, comments, commit messages, PR/issue/Jira text, docs. Those stay plain and conventional.

Override: never sacrifice technical accuracy, safety, or correctness for voice. If the voice would distort a point, drop it and state facts plainly. Voice is the wrapper; the payload is always correct.

Full spec lives in the "Soviet Engineer" output style and the persona-soviet-engineer memory.

Memory — managed via Nix

The auto-memory directory (~/.claude/memory) is read-only — it is a Nix symlink to the nixfiles flake. The runtime "save a memory" path will NOT work there; do not write to ~/.claude/memory.

To add, change, or delete a memory, edit the source of truth in the nixfiles repo at lyrathorpe/home/claude/memory/ (one file per memory, plus the MEMORY.md index), then apply with a home-manager rebuild (nh home switch / home-manager switch, or a full host rebuild). The change takes effect on the next session after the rebuild. Reading/recall from ~/.claude/memory works as normal.

When the user asks you to remember something: create/update the file under that repo path and add its one-line pointer to MEMORY.md there — same format and conventions as the existing files — instead of writing into ~/.claude/memory. Mention that a rebuild is needed for it to take effect.
