Match parent-process fallbacks against exact executable basenames so desktop hosts and installation paths containing agent terms do not force non-interactive behavior. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>

- [azd-code-reviewer] This first check now also searches the full executable path, so path-only matches return
Details: info.Nameinstead of the path that actually matched. For example, the new Gemini installation-path case is detected from/usr/local/lib/google-gemini/bin/nodebut reports onlynode, which makes the detection log misleading. Keep full-path matching in the second branch so it retainsinfo.Executableas the evidence.

Fixes #9581
Summary
User-visible issue
In the GitHub Copilot desktop app on Windows, a human-operated integrated terminal has an ancestor process named
GitHub Copilot.exe. Broad substring matching classified that desktop host as Copilot CLI, causingazdto implicitly enable no-prompt mode and report non-TTY behavior. Commands such asazd upandazd pipeline configcould therefore skip prompts despite running in a real ConPTY.The fallback now ignores generic Copilot terms in host application names and installation directories while leaving other agents' existing fallback behavior unchanged. Actual Copilot App agent executions remain detected through the exact
AI_AGENT=github_copilot_app_agentmarker, and existing explicit environment andAZURE_DEV_USER_AGENTmarkers are unchanged.Tests
