refactor(cli): drop morphsdk compat layer and CJS build plugin

The compat re-export and the build's CJS-redirect plugin only existed to work
around the 'G9' crash that's actually a Bun --splitting bug (now fixed by
splitting:false). With splitting off the morphsdk ESM barrel bundles cleanly,
so import it directly in warpgrep.ts and remove the indirection.
