The api suite is ~95% Postgres integration tests against black, which is only
low-latency from apricot/LAN. Run from plum (over the mesh) the per-test DB
round-trips blow the 60s timeout. New scripts/run-tests.ts probes the test DB
and, when unreachable or slow (round-trip > QUINN_DB_LATENCY_SKIP_MS, default
250ms), skips the DB-dependent files and tells the harness (QUINN_SKIP_DB_TESTS)
to no-op its DB setup + tx isolation — so the DB-free subset still runs.
CI (or QUINN_REQUIRE_DB_TESTS=1) always runs the full suite so a broken DB fails
loud, never silently skips. test-env.ts is the shared gate; test:full / test:no-db
force either mode. From plum: 370 pass, 0 fail (92 DB files skipped, logged).
