fix(contractiles/intend): correct placeholder label (Lustfile → Intentfile.a2ml)

Template placeholder text still referenced the pre-rename Lustfile
name after the lust → intend contractile verb rename. Updates the
body to match the file's current identity. Purely cosmetic; no code
consumes this line.
