Summary

The /create-issue command in create-failing-test-issue.yml currently only supports a single test name per invocation. This should be extended to support multiple test names.

Requested Changes

1. Support multiple test names

Allow specifying multiple test names in a single /create-issue command:

• Multiple positional args:

  /create-issue TestA TestB TestC
  

• Multiple --test args:

  /create-issue --test TestA --test TestB --test TestC
  

Currently the parser in create-failing-test-issue.js rejects a second --test flag with an ambiguity error, and multiple positional args (without a trailing URL) also fail.

2. Fix unnecessary backslash-escaping of underscores in issue titles

Issue titles currently escape underscores like a\_c, producing titles such as:

The backslash escaping is not needed in GitHub issue titles (they are not rendered as Markdown) and makes the titles harder to read and search. Underscores should be left as-is.
