Summary: Add a section to the Fantom `__docs__/README.md` that recommends running the full suite locally with `FANTOM_FORCE_CI_MODE=1`. In CI mode, `globalSetup` pre-builds the entire `(hermesVariant × enableOptimized)` binary matrix once up-front and per-test buck2 invocations are skipped, which eliminates buck2 daemon contention from the worker pool — a common source of sporadic build failures when many workers race to build different binary variants at the same time. CI environments (`SANDCASTLE`, `GITHUB_ACTIONS`) already auto-detect this mode; this just documents it for local use. Changelog: [Internal] Reviewed By: andrewdacenko Differential Revision: D101795648
