Pascal/Delphi lets a no-arg method or procedure drop its parens, so the call
parses as a bare `exprDot` (not an `exprCall`) and was never recorded as a call —
callers/impact/trace missed all of them (e.g. `Obj.Free`, `List.Clear`, the
paren-less factory chain `TFoo.GetInstance.DoIt`).
extractPascalParenlessCall handles these, wired into visitPascalBlock scoped to
STATEMENT position only: a bare `Obj.Field;` statement is a no-op, so a
statement-level dot expression is a call — but a dot in assignment LHS/RHS or a
condition is left alone, since there it's genuinely ambiguous with a
field/property access. The chained paren-less form reuses the #750 chain encoding
(gated on the Delphi `TFoo`/`IFoo` type convention) and resolves the same way.
PascalCoin A/B: +1131 / -1 — purely additive, and all 1131 new edges resolve to
METHOD nodes (zero field/property false positives, confirming the statement-level
gate). 3 new synthetic tests (paren-less call, paren-less chained factory, and the
property-write/read non-extraction guard). EXTRACTION_VERSION 16->17. Full suite green.
