GQL performance optimization

【需求描述】
1. GQL性能优化 ：
MATCH
(a:person where a.id = 4)-[e:created]->(b),
(c:person) -[:knows]-> (d where d.id = 2),
(a:person where id = 4) <-[:knows]- (c)
RETURN a, b, c, d

【期望产出】
1. 对上述查询进行优化，在LDBC SF1上提升50%。

如有疑问请联系： @puuuuug

Start by reproducing the supplied GQL query against the LDBC SF1 workload and identify the query-processing entry points involved; the issue names no files or tests. Compare the baseline with the requested 50% improvement on LDBC SF1, and treat the work as done only when the query remains correct and the benchmark demonstrates that gain.
