EXAMPLES:

  # Detect settings and choose between them at a terminal
  iwe init

  # Accept the detected settings without prompting
  iwe init --auto

  # Inspect the evidence before committing to anything
  iwe init --dry-run

  # Let an agent read the full report, then apply a reviewed decision
  iwe init --dry-run --json
  iwe init --auto --link-format wiki --library notes

  # Skip detection and write the static template
  iwe init --defaults

  # After initialization, edit config
  $EDITOR .iwe/config.toml

OUTPUT:

  Writes .iwe/config.toml, each detected value preceded by a comment citing
  its evidence. Prints a scan summary, any warnings, and how many files
  `iwe normalize` would rewrite.

  Exits 2 if .iwe already exists.
