## Summary Set `RUST_MIN_STACK=8388608` for Rust test entry points so libtest-spawned test threads get an 8 MiB stack. The Windows BuildBuddy failure on #18893 showed `//codex-rs/tui:tui-unit-tests` exiting with a stack overflow in a `#[tokio::test]` even though later test binaries in the shard printed successful summaries. Default `#[tokio::test]` uses a current-thread Tokio runtime, which means the async test body is driven on libtest's std-spawned test thread. Increasing the test thread stack addresses that failure mode directly. To date, we have been fixing these stack-pressure problems with localized future-size reductions, such as #13429, and by adding `Box::pin()` in specific async wrapper chains. This gives us a baseline test-runner stack size instead of continuing to patch individual tests only after CI finds another large async future. ## What changed - Added `common --test_env=RUST_MIN_STACK=8388608` in `.bazelrc` so Bazel test actions receive the env var through Bazel's cache-keyed test environment path. - Set the same `RUST_MIN_STACK` value for Cargo/nextest CI entry points and `just test`. - Annotated the existing Windows Bazel linker stack reserve as 8 MiB so it stays aligned with the libtest thread stack size. ## Testing - `just --list` - parsed `.github/workflows/rust-ci.yml` and `.github/workflows/rust-ci-full.yml` with Ruby's YAML loader - compared `bazel aquery` `TestRunner` action keys before/after explicit `--test_env=RUST_MIN_STACK=...` and after moving the Bazel env to `.bazelrc` - `bazel test //codex-rs/tui:tui-unit-tests --test_output=errors` - failed locally on the existing sandbox-specific status snapshot permission mismatch, but loaded the Starlark changes and ran the TUI test shards
