69eca21fb5 feat: password change endpoint with full session rotation
Adds the pre-1.0 password-change story flagged by the audit. Browser
users and bot owners both go through PATCH /api/v1/auth/me/password
with the current + new password in the body.

Implementation in `api::auth::change_password`:
- CurrentUser-gated: 401 if unauthenticated.
- Verifies current_password against the stored argon2 hash. Wrong
  current → 401 unauthenticated, matching the login contract.
- new_password runs through the same `validate_password` used at
  registration (≥8 chars). Weak → 400 invalid_input.
- On success, wraps the swap in a single transaction:
  - UPDATE users.password_hash with a fresh argon2 hash.
  - DELETE every session for this user (signs out other devices —
    any cookie stolen before the change is dead now).
  - INSERT a new session and mint a fresh cookie so the caller stays
    logged in.
- 204 + Set-Cookie on success.

Bot tokens (api_tokens) are intentionally left alone. They're explicit
opt-in credentials that the user can already audit and revoke
individually via DELETE /auth/tokens/{id}; rotating them on every
password change would surprise CI scripts.

Repo refactor: `repo::session::create` accepts `impl PgExecutor<'_>`
(same pattern feat/uploads used for chapters), and a new
`session::delete_all_for_user` covers the "sign out everywhere"
write. The existing `delete_by_token_hash` (used by logout) is
unchanged.

Coverage in tests/api_auth.rs (4 cases):
- change_password_rotates_sessions_and_swaps_credentials — happy path
  asserts the new cookie differs from the original, that both the
  original cookie AND a second-device cookie become invalid, that the
  new cookie keeps working, that login with the old password fails
  (401) and login with the new password succeeds.
- change_password_rejects_wrong_current_with_401 — wrong current
  password returns 401 unauthenticated.
- change_password_rejects_weak_new_password — new_password "short"
  returns 400 invalid_input.
- change_password_requires_authentication — no cookie returns 401.

README updated with the new endpoint in the auth table.

Lockstep version bump to 0.10.0.

2df4084c56 test: tighten audit-flagged tests and add missing coverage
Tightens three tests whose names overstated what they checked:

- `login_succeeds_and_rotates_session` now asserts the login cookie
  differs from the registration cookie, and that the registration
  cookie is still valid after login (the documented contract).
- `storage::local::rejects_path_traversal` exercises three extra
  rejection paths the existing implementation already handled but the
  tests didn't probe: `a/./b`, the single-segment `.`, and the empty
  segment `a//b`.
- `create_and_use_bot_token` asserts that `token_hash` is *absent*
  from the response (`get(...).is_none()`), not just `is_null()`,
  which would have accepted an explicit `"token_hash": null` payload
  too.

Adds four coverage cases that the audit flagged as missing:

- `me_rejects_expired_session` — hand-craft a session row with
  `expires_at = now() - 1h`, hit `/auth/me` with the matching cookie,
  expect 401 + `unauthenticated`. Proves the extractor's
  `expires_at > now()` filter is wired.
- `concurrent_manga_bookmarks_serialised_by_unique_index` — spawn two
  POSTs in parallel for the same `(user, manga, chapter=null)`,
  assert one wins (201) and one collides (409) via the partial unique
  index from migration 0004.
- `bookmark_create_accepts_bearer_token` — mint a bot token and POST
  /bookmarks with `Authorization: Bearer`, asserting `CurrentUser`
  resolves identically to the cookie path on a write endpoint (not
  just `/auth/me`).
- Three new unit tests on `app::cors_layer` covering the allowlist
  (origin reflected, credentials true), a foreign origin (no
  allow-origin header emitted), and the same-origin default (empty
  allowlist emits no CORS headers at all).

`cors_layer` is `pub(crate)` now so the tests in `app::tests` can
reach it; the function itself is unchanged.

No version bump.

785b9755cf bugfix: case-insensitive usernames, reject non-positive bookmark page
Two related correctness fixes from the audit:

- Username uniqueness was case-sensitive (`username text UNIQUE`), so
  "Alice" and "alice" could both register and then race on login.
  Migration 0006 adds a unique index on `lower(username)`; the
  existing constraint is kept (overlapping but cheap) to avoid a
  destructive migration on any deployments that may already exist.
  `repo::user::find_by_username` now matches on `lower(username) =
  lower($1)` so login is case-insensitive against the same index.
  Test: registering "alice" then "Alice" returns 409 conflict; login
  with "ALICE" succeeds against the existing user.

- `POST /api/v1/bookmarks` silently accepted `page: 0` and `page: -1`
  even though both are nonsense for a 1-indexed page number. Reject
  with 422 `validation_failed` and `details.page` populated, matching
  the pattern used for missing-metadata / empty-title elsewhere. Test
  covers both 0 and -1.

Lockstep version bump to 0.9.4.

383cfbed3b feat: argon2id passwords, session cookies, bot bearer tokens
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.
