fix(install): replace all managed files atomically

Browse Source 
Write config.toml, settings.json, the manifest, and every other managed file to
a temporary sibling and rename it over the target, so an interrupted run
cannot leave a partly written file. Previously only SKILL.md was replaced
this way.
