Fix sweep script crashing on locked issues

The sweep job (https://github.com/anthropics/claude-code/actions/runs/21983111029/job/63510453226)
was silently failing when closeExpired tried to comment on a locked issue,
causing a 403 from the GitHub API.

Two issues:

1. closeExpired didn't skip locked issues like markStale already does.
   Adding the same `if (issue.locked) continue` guard fixes this.

2. The error was swallowed by `main().catch(console.error)` which logs
   to stderr but exits 0, so CI reported success despite the crash.
   Replaced the main() wrapper with top-level await so unhandled errors
   properly crash the process with a non-zero exit code.
