fix(resolution): gate the Lua/Luau annotation pattern against method-call self-match (#1124) (#1131)

Lua method-call syntax (lg:Log()) is byte-identical to the Luau type-annotation
shape (lg: Logger), and the receiver-type scan starts on the call's own line —
so any PascalCase method call self-matched as "type = Log" before the scan
reached the real declaration, silently dropping the calls edge whenever two or
more classes shared a method name.

The annotation pattern now rejects a capture followed by any of Lua's three
call forms; its leading [\w.] lookahead alternative prevents backtracking from
shrinking the capture to dodge the gate. Gated rather than dropped: the pattern
is the only type source for Luau typed params and annotated locals whose
initializer isn't T.new().
