Record parameters marked with "TOGGLE Off" by adding an optional
toggleOffParameterNames field and including an extra <var>_defined global
for each such parameter in createCdlEventHandlerSnippet.
To support this, the parser was changed from a brace-delta approach to a
token-based scanner so nesting and the association between a PARAM and its
TOGGLE can be tracked reliably. Added unit tests that verify detection,
case-insensitivity, and ignoring TOGGLE occurrences inside comments/strings
or other events.
