Reports GDScript variable and constant declarations that miss an explicit type hint when it can be inferred, and flags typed use of the := assignment.
Notes:
Variant/null type.:= assignment cannot be used together with an explicit type hint. Use = when a type is specified.Example:
var hp = 100 # suggests: var hp: int = 100
var hp: int := 100 # error: ":=" assignment cannot be typed
var hp: int = 100 # OK
