Summary

Follow-up to #1329: reclaim fixture roots created by supporting tests that call node:test directly after each case. Keep each root available through its test's own teardown hooks, including nested and failed cases. If a teardown hook throws and skips the late cleanup hook, drain that test's pending roots before the next case or the parent's teardown.

Scope roots created inside a direct test's async teardown to that test. Preserve intentional process-lifetime fixtures: the shared lifecycle inspection project and its sibling fake runner, module-level provider homes, and the Smithers poison binary. Bun continues to use the scoped runtime wrapper because its module cache does not register these direct hooks across multiple files.

Fixes #1322.

• Prettier and git diff --check
• Node focused supporting tests: 28 pass, 0 fail
• Shared lifecycle fixture across two cases: 2 pass, 0 fail
• Bun two-file focused tests: 10 pass, 7 intentional Node-only skips, 0 fail

Confidence Score: 5/5

The PR appears safe to merge; no new actionable issues remain.

Summary

This PR removes temporary fixtures after direct Node tests while keeping them available through each test’s teardown.

• Direct Node tests keep scratch through teardown and clear it afterward.
• Shared test fixtures stay available for as long as later cases need them.

Both earlier, unnumbered findings are addressed by the pending-scope drain and teardown-specific scope. No new actionable issues were found.
