constant_time_eq (and the `subtle` dependency) was never wired into any
comparison — the module doc wrongly claimed token comparison used it, but lookup
is an indexed DB equality on the 256-bit SHA-256 hash, so there's no in-process
secret compare to time-attack. Delete the dead fn, its test, and the unused
`subtle` dep; rewrite the doc. No behaviour change.

try_acquire used .expect on lock(), so a single panic while holding either
limiter mutex would poison it and make every subsequent auth request re-panic
— one blip became a persistent auth outage. Recover the guard with
unwrap_or_else(|e| e.into_inner()) so the limiter keeps serving.

A single global token bucket let one attacker at the sustained rate 429
every user's login/register/change-password. Key buckets by client IP: the
SvelteKit proxy now stamps the real peer address onto X-Forwarded-For
(overriding any client-supplied value, anti-spoof), and axum reads it via a
ClientIp extractor — but only when AUTH_TRUSTED_PROXY is set, else it falls
back to the shared bucket (today's behavior). The per-IP map is bounded
(10k IPs, idle buckets pruned) so a spoofed-IP spray can't grow it.
AUTH_TRUSTED_PROXY defaults false (safe for a directly-exposed backend);
compose sets it true since the proxy is the single trusted hop.
Bump to 0.124.12.

Argon2id hashing (~15-50ms, 19 MiB) ran synchronously inside async
handlers, stalling every task sharing those runtime worker threads under
concurrent auth load. Add spawn_blocking wrappers hash_password_async /
verify_password_async and switch all async call sites; sync primitives
stay for the login timing-equaliser and unit tests. Bump to 0.124.1.

Adds an `is_admin` flag on users plus the substrate every later PR in the
admin feature builds on:
- migration 0018 adds the column with default false
- `repo::user::bootstrap_admin` creates or promotes the user named by
`ADMIN_USERNAME` at startup, hashing `ADMIN_PASSWORD` only when the row
is new — never overwriting an existing hash, so an operator can rotate
the admin password via the UI without env-var conflict
- `CurrentSessionUser` extractor accepts only the session cookie;
`RequireAdmin` composes over it and additionally requires
`user.is_admin`. Bearer tokens are intentionally excluded so an
admin's bot token never inherits admin authority (privilege-escalation
surface that bites every "API keys reuse user perms" auth design)
- demotion is instant: `RequireAdmin` re-reads the user row each request
`/api/v1/auth/me` now exposes `is_admin`; no other response embeds
`User`, so no privacy fanout to audit.
Three features bundled into one release:
- rate-limit /auth/login, /register, /me/password (token bucket,
5 req/sec sustained with 10-request burst by default; 429 +
Retry-After header on hit; tracing::warn! per hit so operators
see attack patterns; AUTH_RATE_PER_SEC / AUTH_RATE_BURST env knobs)
- handle SIGTERM for graceful container stops (replaces bare
ctrl_c() with a select over ctrl_c + SignalKind::terminate() so
docker compose stop runs the daemon shutdown path instead of
letting Chromium leak past SIGKILL)
- clear session.user on 401 from any API call (setOn401Hook in
api/client.ts, registered from session.svelte.ts gated on
$app/environment::browser so the SSR bundle never installs it;
fixes "logged in but no bookmarks/collections" mid-session
expiry state)

Adds the full auth flow. Reads stay public; writes (currently only POST
/api/v1/mangas) require a CurrentUser. Both browsers and bot scripts hit
the same endpoints — they just present credentials differently.
Migration 0002_auth.sql introduces users.password_hash, a sessions
table, and an api_tokens table. Sessions and api_tokens store only
sha256(raw_token) — the raw value lives in the cookie or the
Authorization header.
New endpoints under /api/v1/auth/:
- POST /register — argon2id hash, creates a session, sets cookie.
- POST /login — verifies, rotates to a fresh session (old ones expire
naturally so other devices stay signed in).
- POST /logout — deletes the server-side session row + clears the
cookie via Max-Age=0.
- GET /me — current user via the new CurrentUser extractor.
- POST /tokens — issue a bot bearer token; raw value returned exactly
once at creation.
- DELETE /tokens/{id} — owner-only: 404 if unknown, 403 if it exists
but belongs to another user, 204 on success.
The CurrentUser axum extractor resolves cookie first, then
Authorization: Bearer; failure → AppError::Unauthenticated (401). New
AppError variants Unauthenticated/Forbidden/Conflict carry the matching
envelope codes; the top-level match in `code()` stays exhaustive.
Backend integration coverage in tests/api_auth.rs: register sets a
HttpOnly SameSite=Lax cookie and never leaks password_hash; duplicate
username → 409; weak password → 400; login rotates the cookie; wrong
password / unknown user → 401; /me with vs without cookie; logout
invalidates the cookie; bot-token roundtrip via Bearer; user A cannot
delete user B's token (403); unknown delete → 404.
Frontend:
- lib/api/auth.ts — typed wrappers; me() returns null on 401.
- lib/session.svelte.ts — per-tab user state with a seq counter to
guard against an in-flight /me clobbering a fresh setUser.
- lib/api/client.ts — request<T> returns undefined for 204.
- routes/login + routes/register — forms with action="javascript:void(0)"
so the no-JS path is a no-op (avoids the hydration-race where a
pre-attach click would submit via the browser default).
- routes/+layout.svelte — session-aware nav: spinner → user + Logout,
or Login / Register.
- e2e/auth-flow.spec.ts — login flips the layout, logout flips back;
bad credentials surface the API error message.
Config grows AuthConfig (cookie_secure, cookie_domain, session_ttl_days)
and CORS_ALLOWED_ORIGINS. CORS middleware is mounted in app::build and
stays a no-op (same-origin) until origins are listed.
Lockstep version bump to 0.3.0.
