### What problem does this PR solve?
Issue Number: close #xxx

Problem Summary:
### Release note
Support short-circuit multi-get for non-cloud prepared queries with one key
IN predicate and equality parameters covering the remaining unique-key columns.
The default IN limit is 30; the limit is checked during planning, and changing
it does not invalidate an existing prepared point-query cache. Reprepare or
another replanning event applies the new limit. Queries exceeding the limit
during planning and Cloud queries use regular execution. Cached multi-get does
not support parameter type changes requiring different comparison semantics.
### Check List (For Author)
- Test <!-- At least one of them must be included. -->
- [x] Regression test
- [x] Unit Test
- [ ] Manual test (add detailed scripts or steps below)
- [ ] No need to test or manual test. Explain why:
- [ ] This is a refactor/code format and no logic has been changed.
- [ ] Previous test can cover this change.
- [ ] No code files have been changed.
- [ ] Other reason <!-- Add your reason? -->
- Behavior changed:
- [ ] No.
- [x] Yes. Yes. Eligible prepared queries use batched point lookup;
unsupported shapes use regular planning. The IN limit is a planning-time
eligibility check and is not rechecked on cache reuse. Callers must preserve
compatible parameter types when reusing a multi-get cache; incompatible
rebinding no longer triggers automatic replanning.
- Does this need documentation?
- [ ] No.
- [ ] Yes. <!-- Add document PR link here. eg:
