- Entire stdout+stderr was passed to both title and body for the github
issue, resulting in a failure due to github's validation
Fixes:
- Pass only the line containing "simulation failed:" as title
- Pass max 50 lines following title as body
- Truncate title and body to 255 and 65536 chars respectively
before posting github issue, just to be sure
code was trying to consume the same readablestream twice: once in
the timeouter's catch block, and a second time in the body of the
try block before postGithubIssue() could run.
