* feat(registry): persist pnpr users and tokens to disk
Backs UserStore with a verdaccio-shaped htpasswd file (bcrypt $2y$
hashes, atomically rewritten on every adduser) and TokenStore with a
SQLite database that stores SHA-256 token hashes plus the per-record
fields the upcoming /-/npm/v1/tokens surface will need (created_at,
last_used_at, readonly, cidr_whitelist).
Configuration mirrors verdaccio's auth.htpasswd.{file,max_users}
under the existing YAML schema; tokens default to a tokens.db
sibling of htpasswd, overridable via auth.tokens.file. max_users=-1
disables registration end-to-end. Both files are written via
tmp+rename and loaded eagerly on startup so a malformed htpasswd
fails fast rather than booting with a silent empty user list.
Closes#11974.
* fix(registry): use OS CSPRNG, satisfy dylint + rustdoc
- TokenStore's per-process secret now comes from getrandom (OS-backed
CSPRNG) instead of time/pid/stack address. Tokens are derived from
this secret + a per-issue nonce, so weak entropy was making mint
outputs guessable to an attacker who could bound those inputs.
- Reorder derives on AuthConfig / HtpasswdConfig / TokensConfig /
MaxUsers to satisfy perfectionist::derive-ordering (prefix-then-
alphabetical: Debug, Default first, then the rest).
- Re-export auth::identify so the rustdoc link from the now-public
UserStore::verify resolves; rustdoc::private-intra-doc-links no
longer fails the workspace doc build.
- Drop the inaccurate "+inf" mention from MaxUsers' doc — serde-saphyr
treats +inf as a float and can't deserialize it into i64, so the
only way to get Unlimited is to omit max_users.
