描述

We have ZygoteRuleConfig for this, so there should be no major technical limitations. rrules generally have far better UX than @adjoints (as anyone who has had to read a stacktrace from Zygote can attest). The ultimate end goal would be to get rid of ZygoteRules entirely.

研究方向
Identify all existing @adjoint definitions in the Zygote.jl codebase. For each one, write an equivalent rrule using ZygoteRuleConfig, ensuring correct behavior. Test with ChainRulesTestUtils and verify that stack traces improve. The conversion is systematic but requires deep understanding of both old and new APIs. No specific files are highlighted in the issue; maintainers have not provided further guidance beyond the title and description.
