## Summary
- When `--bail` caused an early exit after a test failure, the JUnit
reporter output file (`--reporter-outfile`) was never written because
`Global.exit()` was called before the normal completion path
- Extracted the JUnit write logic into a `writeJUnitReportIfNeeded()`
method on `CommandLineReporter` and call it in both bail exit paths
(test failure and unhandled rejection) as well as the normal completion
path
Closes#26851
## Test plan
- [x] Added regression test `test/regression/issue/26851.test.ts` with
two cases:
- Single failing test file with `--bail` produces JUnit XML output
- Multiple test files where bail triggers on second file still writes
the report
- [x] Verified test fails with system bun (`USE_SYSTEM_BUN=1`)
- [x] Verified test passes with `bun bd test`
