Address code review feedback from CodeRabbit and Augment

- Move "Setting up..." log after conflict check so it only shows when
  install will proceed
- Fix rm command: add -rf flags and correct quoting for glob outside quotes
- Improve error wording: "ancestor installation" instead of misleading
  "ancestor directory"
- Use case-insensitive startsWith for bmad file detection (macOS/Windows)
- Document ancestor_conflict_check in the installer config schema
