Fix V8StackTraceIterator to handle frames without parentheses ( #23034 )
...
## Summary
- Fixes V8StackTraceIterator terminating early when encountering stack
frames without parentheses (e.g., "at unknown")
- Ensures complete stack traces are shown by `Bun.inspect()` even after
`error.stack` property is accessed
- Addresses the root cause that PR #23022 was working around
## Problem
When the V8StackTraceIterator encountered a stack frame line without
parentheses (like `at unknown`), it would:
1. Set `offset = stack.length()`
2. Return `false`, terminating the entire iteration
3. Only parse frames before the "unknown" frame
This caused `Bun.inspect()` to show incomplete stack traces after the
`error.stack` property was accessed, as documented in issue discussions
around PR #23022 .
## Solution
Changed the parser to continue iterating through subsequent frames
instead of terminating. Frames without parentheses are now treated as
having a source URL but no function name or location info.
## Test plan
- [x] Added regression test
`test/regression/issue/23022-stack-trace-iterator.test.ts`
- [x] Verified existing stack trace tests still pass
- [x] Manually tested with Node.js stream errors that trigger this code
path
### Before fix:
```
error: Socket is closed
code: "ERR_SOCKET_CLOSED"
at node:net:1322:32
```
### After fix:
```
error: Socket is closed
code: "ERR_SOCKET_CLOSED"
at unknown:1:1
at _write (node:net:1322:32)
at writeOrBuffer (internal:streams/writable:381:18)
at internal:streams/writable:334:16
at testStackTrace (/workspace/bun/test.js:8:10)
