Implements PLAN.md Phase 2: the library every later phase is built on,
as pure code under server/internal/matrix with no HTTP and no storage.

canonicaljson: the canonical JSON encoding, hand-written because
encoding/json escapes <, > and & and accepts floats. Integers only, in
[-(2^53)+1, 2^53-1]; lone surrogate escapes rejected rather than turned
into U+FFFD.

signing: the Signing JSON algorithm alongside the existing key handling,
and one lenient base64 decoder shared by the packages above it.

id: identifier grammars as they appear inside events, deliberately laxer
than userapi's account rules because rooms carry historical user IDs.

roomversion: the registry. Versions 3 to 12 are supported, each written
out in full as a Rules value with the flags the other packages read.
Versions 1 and 2 are known but refused: their event format and state
resolution v1 wait for federation. createRoom will default to 11, as the
spec asks for a while after 1.16, with 12 available.

event: PDU parsing and validation, content and reference hashes, event
IDs, the redaction algorithm for every supported version, signing and
verification, and a Builder.

auth: the authorisation rules in spec order, power levels with their
defaults, v12 creators with infinite power, the auth events selection
algorithm, rule 3's auth_events checks, and the separate test for
whether a redaction applies. Comments use the room version 12 rule
numbering, with the version 11 numbers given where they differ.

stateres: state resolution v2, and version 12's amendment (an empty
starting state and the conflicted state subgraph).

Tested against the spec's own vectors byte for byte: the canonical JSON
examples, both JSON signing vectors and both event signing vectors.
State resolution ports scenarios from Synapse's suite. canonicaljson
and event.Parse have fuzz targets.

The capabilities endpoint now advertises the registry instead of a
hard-coded "11". docs/event-core.md describes the packages and the
known gaps.

Implements PLAN.md Phase 1. A client can now register, log in, manage its
devices and set its profile; an operator can create accounts and flip the
runtime switches. There are still no rooms and no real /sync.

userapi: accounts, argon2id passwords in PHC format, devices, access and
refresh tokens stored as SHA-256 hashes, account data and the admin flag.
Its storage interface is storage.UserStore, implemented once in sqlstore
with `?` placeholders; the postgres driver supplies a rebind function and
unique-violation recognition rather than keeping a second copy of thirty
statements. Timestamps in these tables are int64 milliseconds, the unit the
Client-Server API uses on the wire.

Client-Server API: register (user-interactive auth with m.login.dummy and
optional registration tokens), register/available, token validity, login
with m.login.password, logout, logout/all, refresh, account/whoami,
capabilities, devices/* with password-gated deletion, profile/*, global and
per-room account data.

GET /sync is a deliberate placeholder: it answers a valid token with an
empty but well-formed response and refuses a revoked one. Phase 1 has no
rooms, so that is the whole truth, and it is what makes session revocation
observable. Phase 4 replaces it with the syncapi.

Auth middleware resolves a bearer token (header or the legacy query
parameter) to a device and user, answering an expired token with the soft
logout the spec asks for. Rate limiting is a token bucket per endpoint class
keyed on the client address, returning M_LIMIT_EXCEEDED with retry_after_ms.

adminapi v1 under /_warp/admin/v1: admin-only auth via a normal Matrix
token, GET/PUT /federation and /registration driving internal/settings and
reporting a config-pinned switch as a 409, GET/POST /users, GET /stats.

warp create-account [--admin] creates the first account straight in the
database, so a new install with registration off has a way in.

Complement is wired up for the federation=off profile: an image meeting its
contract, an entrypoint that configures Warp entirely from WARP_*
variables, and a runner that builds, clones and executes the target set
(TestRegistration, TestLogin, TestDeviceManagement). It has not been run
yet -- there is no container runtime on the development machine -- so the
three tests' assertions were read from the Complement sources and pinned as
httptest tests instead, and CI gained a job that runs the real thing.

Also fixes a .gitignore bug from Phase 0: the unanchored `warp` pattern,
meant for the built binary, also matched the directory server/cmd/warp and
silently excluded the entire command package from the repository. The
binary patterns are now anchored to the repository root, and cmd/warp is
committed for the first time.
