node:vm: report compileFunction body lines relative to lineOffset when it is 0 - #38240

The uncaught-error source preview strips `wrapperTextLength` from the displayed line but the caret column comes from `getAdjustedPositionForBytecode`, which subtracts `wrapperColumns` — with `columnOffset > 0` these differ, so the `^` lands `columnOffset` columns past the throw. `handleException` avoids this by shifting the caret by `startColumnZeroBased + wrapperPrefixLength` (i.e. the same quantity as the strip); the fix here is to also subtract `wrapperTextLength - wrapperColumns` (== columnO

The `run` helper sets `stdout: "pipe"` but only awaits `proc.stderr.text()` and `proc.exited` — stdout is never drained (REVIEW.md's subprocess rule requires draining every piped stream in the same `Promise.all`, or drop `stdout: "pipe"` since nothing is asserted on it). It also runs `expect(exitCode).toBe(1)` before returning stderr for the content assertions, so an unexpected exit code fails with just "expected 1, received N" and no stderr shown; CLAUDE.md/REVIEW.md ask for content-before-exit
