Implements PLAN.md Phase 10.
Simplified Sliding Sync (MSC4186) is served at the unstable
org.matrix.simplified_msc3575 endpoint and advertised in /versions. Lists
are sorted by activity and filtered by DM, invite, encryption, room type,
space and tag; room subscriptions, required_state with wildcards, $ME and
$LAZY, and the to_device, e2ee, account_data, receipts and typing
extensions are supported. Per-connection state is kept in memory and an
unknown pos answers M_UNKNOWN_POS.
Threads and relations: m.relates_to is indexed on roomserver_events
(migration 0012), /relations (with recursion) and /threads are served, and
every event a timeline read returns carries its m.thread, m.replace and
m.reference summaries in unsigned.m.relations. Notifications carry a
thread ID (migration 0013): threaded receipts clear only their thread, and
sync reports unread_thread_notifications when the filter asks.
Spaces: /hierarchy walks a space breadth first, asking other servers about
rooms this one is not in through the new federation hierarchy endpoint;
room_summary describes one room. /search runs on FTS5 (sqlite, pocketbase)
or tsvector (postgres), bounded to what each user may see, with context,
profiles, state, grouping and paging.
The PocketBase driver is real: the sqlite schema and store on an embedded
PocketBase app's database, with media in its filesystem, local or S3
(database.pocketbase.s3). It runs the full storage test suite.
Ops: OpenTelemetry tracing over OTLP/HTTP (tracing.*), with server spans
per route, component spans, and trace propagation on federation, push and
application service calls. New metrics for persisted events, waiting
syncs, sliding sync connections and the database pool, with a Grafana
dashboard. deploy/ adds a Compose setup (PostgreSQL, Prometheus, Grafana,
Jaeger) and a Helm chart; cmd/warp-loadtest loads a server and reports
request and delivery latencies.
The load tester found a long-standing bug, fixed here: on a server where
no account data had been written, every incremental /sync re-sent the push
rules and returned at once, and an all-zero token was taken for an initial
sync, so long polls became busy loops.
The PostgreSQL migrations and search dialect compile but were not run
against a live PostgreSQL in this change.

Scaffolds the server module and everything Phase 0 of PLAN.md calls for:
a binary that boots, serves its discovery endpoints and nothing else yet.
- config: one YAML file plus per-field WARP_* environment overrides,
unknown fields rejected, validation that reports every problem at once
- logging and metrics: slog, a Prometheus registry, per-route HTTP
instrumentation labelled by pattern rather than path
- httputil: the Matrix error envelope, error-returning handlers, CORS,
request logging, panic recovery, and a router over http.ServeMux
- endpoints: /_matrix/client/versions, /.well-known/matrix/client,
/.well-known/matrix/server (gated), /healthz, /metrics, and
M_UNRECOGNIZED for everything else
- storage: driver registry, shared database/sql base, checksummed
migration runner, sqlite and postgres drivers, pocketbase stub
- settings: server_settings table behind a cached service, so the
federation and registration switches change without a restart
- federation: the gate that makes federation a runtime mode
- cmd/warp: serve, migrate, generate-keys, version
- Makefile, golangci-lint v2, GitHub Actions CI (Linux and Windows tests,
race on Linux, storage tests against PostgreSQL, lint, boot smoke test),
Dockerfile, example config and docs
