Oleksandr Bezdieniezhnykh 001e80fe96 [AZ-585] [AZ-586] ResLim+Perf NFT tests; close test cycle 1
Batch 4 of test implementation cycle 1 (existing-code Step 6, final batch).

- AZ-585 SteadyStateLoadTests + ColdStartRssTests: NFT-RES-LIM-01..04.
  SteadyStateLoadFixture runs one 5-min sustained-load window and samples
  RSS (docker stats), Npgsql conns (pg_stat_activity), and FDs
  (/proc/1/fd) every 5s; three test methods assert independently. All
  SkippableFact-gated on docker primitives.
- AZ-586 PerformanceTests: NFT-PERF-01..04. Sequential single-client,
  5 warm-ups + N measured calls, P50+P95 via LatencyPercentiles, recorded
  to PERF_RESULTS_FILE. Tagged Category=Perf so default gate excludes them.

Infrastructure:
- entrypoint.sh now applies --filter "${TEST_FILTER:-Category!=Perf}"
  per AZ-586 (default CI gate excludes performance).
- MetricCsvRecorder: idempotent CSV appender keyed on env var, used by
  both Perf and ResLim categories.

Step 6 (Implement Tests) is complete. Final report at
_docs/03_implementation/implementation_report_tests.md handoffs the
full-suite gate to test-run/SKILL.md (Step 7).
