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.

# User identity registry -- pure data, no machinery. Keyed by username.
#
# Each entry describes WHO a user is (display name, email, authorized/signing
# keys, supplementary groups). The reusable modules read this indirectly:
# - system: modules/users.nix builds users.users.* from `userRegistry`
# (specialArg) restricted to the host's `hostUsers` set.
# - home: home/git.nix and home/desktop.nix read the per-user `identity`
# module arg, which mkHost derives from the matching registry entry.
#
# The login name is injected by mkHost as `identity.username`, so it is not
# repeated inside each entry here.
