Subject: [PATCH] fix(filter): allow bare @ adjacent to an operator without
 whitespace

The current-node token @ was only substituted for _$_v when followed by
'.', whitespace, ')' or '['. A bare @ directly before a comparison or
arithmetic operator (e.g. $[?(@>1)] or $[?(@===2)]) was left untouched,
so the compiled filter script started with a literal @ and failed to
parse under both the safe and native evaluators. Extend the delimiter
set with the operator characters so these expressions evaluate; @ inside
identifiers and quoted keys (e.g. @['@tag']) stays protected.
