Subject: [PATCH] perf(linter/eslint/no-extra-boolean-cast): narrow AST
 dispatch (#28362)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Handle optional Boolean calls through their call nodes while retaining
chain context for diagnostics and fixes. Reduce fixture callbacks from
72,504 to 71,712.
