[BTS-2237] Skip conflict test on instrumented builds

[johann-listunov]

Introduce a check to skip conflict-producing test on instrumented server builds as they take too long.

---

Note

Adds a build-check to early-return the retryOnConflict: 100 test on ASAN/TSAN/coverage builds to avoid timeouts.

• Tests:
  • Update src/test/31-conflicts.ts:
    • In the "when set to 100" case, call db.version(true) and early-return when version.details.asan, version.details.tsan, or version.details.coverage are "true", preventing long-running conflict/retry loops on instrumented builds.
