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.
