tree-sitter-swift gives a protocol's body-less method requirement its own
node type, protocol_function_declaration, instead of reusing the
function_declaration used inside a class or struct. The Swift config's
function_types only listed function_declaration, so a protocol like
protocol Drawable {
func draw()
func area() -> Double
}
became an empty node - the method contract every conformer must implement
never entered the graph.
Add protocol_function_declaration to function_types and
function_boundary_types. Requirements now surface as .method() nodes hung
off the protocol, their signature type references (return/param types) are
captured, and they stay distinct from a conformer's implementation of the
same name. Stored property requirements are left alone, matching how
stored properties on a class are already handled.
Adds regression coverage for all three.
