GitHub Copilot reads repository-wide instructions only from
.github/copilot-instructions.md (confirmed via GitHub Docs), not a root
copilot-instructions.md. Aligns getProjectInstructionFile with the installer
(runtime-config-adapter-registry installSurface 'copilot-instructions') and
cites the docs source in the doc-comment.
windsurf now also answers to devin-desktop (CLI --devin-desktop) for the Windsurf→Devin Desktop rebrand; all paths unchanged. The .devin/skills/ workspace migration is split to #1085. Closes#792.
