update: fork to support WATER

commit f834753 Author: Gaukas Wang <[email protected]> Date: Thu Dec 28 12:50:37 2023 -0700 fix: failed nonblocking file fd_write subscription Modify to bypass the on-purpose failing for now. More heavy modification is needed to fully address the underlying issue. commit f29a67b Author: Gaukas Wang <[email protected]> Date: Thu Dec 28 12:43:45 2023 -0700 feat: api.Module insert file/socket commit faa3b83 Author: Gaukas Wang <[email protected]> Date: Thu Dec 28 12:33:26 2023 -0700 feat: CompiledModule dump imports and exports commit d8e5ce2 Author: Gaukas Wang <[email protected]> Date: Thu Dec 28 12:29:09 2023 -0700 update: README badge Point the badge to our fork instead. commit 911ea31 Author: Gaukas Wang <[email protected]> Date: Thu Dec 28 12:27:59 2023 -0700 fix: disable a certain upstream CI This CI won't pass anyways due to spec test.
