build: prevent regex from matching function and class declarations in jsdoc-doctest rule

The RE_ANNOTATION regex was incorrectly matching function and class declarations
as variable names when they preceded annotated statements. This caused the rule
to extract 'function' instead of 'bool' in examples like the is-function-array
case, leading to incorrect validation results. Added negative lookahead
(?\!function\s|class\s) to prevent matching lines that start with these keywords,
ensuring only actual variable assignments are captured.
