Code Review

This pull request reduces default Vitest parallelism and introduces a 64GB memory threshold for the large execution profile. It also disables the experimental filesystem module cache for parallel shards by default to mitigate stability issues and moves agent.acp.test.ts to the ACP test suite. A review comment identifies duplicated logic for parsing truthy environment variables and suggests moving it to a shared utility.

[gemini-code-assist]

The logic for checking truthy environment variable values is duplicated here and in scripts/lib/vitest-local-scheduling.mjs (within isSystemThrottleDisabled). Consider moving this to a shared utility function in scripts/lib/vitest-local-scheduling.mjs and exporting it to improve maintainability and consistency across the codebase.
