End-to-end bug fix workflow for the Ktor project. Accepts a GitHub issue (#NUMBER), YouTrack issue (KTOR-NUMBER), or YouTrack URL (https://youtrack.jetbrains.com/issue/KTOR-NUMBER). Fetches the issue, creates a failing reproducer test, commits on a new branch, implements the fix, validates, and opens a PR. Use this skill whenever the user wants to fix a bug from an issue tracker, mentions a KTOR issue number, or references a GitHub issue to fix.
