refactor JitManager and HybridSeJitWrapper for simplify

## Simplify
**Create** > **Init** , hides things like **InitSymbols**

## Error control

- returns `base::Status` on error, not `bool`

## Lifetime control: no manual delete in java

The `HybridSeJitWrapper` in hybridse-sdk is a proxy class to C pointer `HybridSeJitWrapper`. This requires extra config in swig so the proxy class will automatically release C resource from GC

Look at the JitManager and HybridSeJitWrapper classes in the codebase, likely in a jit/ or sdk/ directory. Understand how InitSymbols and manual delete are currently handled. The goal is to refactor creation to hide InitSymbols, change error returns to base::Status, and configure SWIG for automatic lifetime management of the C pointer in the Java proxy. Check existing SWIG interface files for HybridSeJitWrapper.
