Adds the frozen-peer / BadTimeout gate for the Sql driver — the single highest-value integration test. Mirrors the S7 R2-01 blackhole gate: docker pause a DEDICATED mssql mid-poll, assert the next read surfaces BadTimeout within the client-side operationTimeout (≈3s) and well below the server-side CommandTimeout backstop (30s), the driver degrades (Degraded + host Stopped), and docker unpause recovers to Healthy/Running. - Docker/docker-compose.yml: disposable `otopcua-sql-blackhole` mssql on :14333 (never the shared :14330 ConfigDb server) + one-shot seed. - Docker/seed.sql: the two sample tables. - SqlBlackholeTimeoutTests.cs: env-gated (SQL_BLACKHOLE_ENDPOINT); pauses ONLY the hard-coded container name; skips loudly if the endpoint is the shared port 14330; bounds its own wait so a wedged impl fails, not hangs. Offline: clean skip (no socket, no docker shell-out). Claude-Session: https://claude.ai/code/session_01GASWkNEi68FSCtvr6rLoEW

-- Seed for the Sql driver's blackhole / frozen-peer live gate (dedicated container only).

-- Applied once by the compose `mssql-seed` one-shot against the OWNED
|
|
-- `otopcua-sql-blackhole` container. The blackhole test (SqlBlackholeTimeoutTests)
|
|
-- also creates this exact shape defensively on connect, so the two are kept in
|
|
-- parity: a Good baseline poll before the pause depends on `sqlpoll.TagValues`
|
|
-- holding the one seeded row.
|
|
--
|
|
-- Two sample tables mirror the offline SqlitePollFixture / live SqlPollServerFixture
|
|
-- shapes so the gate polls something representative, not a bespoke schema.
