On FAT32, `fs.stat()` updates accesstime, which means file reads are also writes, which means we can't use `usePoll` without degrading users' flash drives. To keep file reads lazy without a larger refactor, I override `getters.dynamix()` as the entrypoint to re-read the boot drive's dynamix config. Consecutive calls to `getters.dynamix()` are a common access pattern, which means we have to memoize to avoid many redundant file reads, so I used a TTL cache with a 250ms lifetime, hoping to scope config files to each request. `getters.dynamix()` is also used synchonously, so bit the bullet and switched away from async reads for simplicity, considering that most reads will be occurring from memory, even during cache misses. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Added a TTL memoized loader utility with exported types. * Added a public function to load Dynamix configuration at startup. * **Refactor** * Startup now uses the deterministic, cached config loader; runtime file-watch for Dynamix config removed. * Simplified config state handling and load-status reporting for more predictable startup behavior. * **Tests** * Added tests for TTL caching, eviction, keying, and conditional caching. * **Chores** * Bumped package versions and updated changelog. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: github-actions[bot] <github-actions[bot]@users.noreply.github.com>
