cheat/cheat 4.5.1 on GitHub

Bug fixes

Fix first-run experience (#721, #730, #771): Declining community cheatsheets during initial setup no longer causes errors on subsequent runs. config.New() now skips missing cheatpaths with a warning instead of a fatal error.
Fix --init output (#773): cheat --init now comments out the community cheatpath by default and includes clone instructions, so the output works as a config file without modification.
Fix stdin buffering in installer prompts: The installer's interactive prompts now read stdin without buffering, allowing cheat to be scripted (e.g., printf "y\nn\n" | cheat).
Fix frontmatter parsing on Windows: Line ending detection in cheatsheet frontmatter now inspects file content instead of checking runtime.GOOS, fixing parsing failures when files have Unix line endings on Windows.
