/**
 * Regression test for #3011: SDK not found.
 *
 * Reporter (Windows / PowerShell 7) ran `npx get-shit-done-redux@latest`,
 * upgrade reported success, but `gsd-sdk` could not be resolved by Claude
 * Code, Git Bash, PowerShell, or WSL. The previous diagnostic was a
 * generic "not on your PATH" with no actionable info; the user couldn't
 * find where the shim was written or how to add it to PATH for each shell.
 *
 * Fix: formatSdkPathDiagnostic() returns a typed IR with the shim
 * location, platform-specific PATH-export commands, and an npx-note
 * when running under an `_npx` cache. The console renderer in install.js
 * just emits each line; tests assert on the IR fields directly.
