[PR] fix: fix compile and format [paimon-cpp]
lucasfang opened a new pull request, #143:
URL: https://github.com/apache/paimon-cpp/pull/143
### Purpose
Linked issue: N/A
This PR fixes compilation errors and applies pre-commit formatting corrections across multiple test files and source files. Key changes include:
- **Compilation fixes**: Corrected API usage in test files (e.g., `list_array->values().get()` instead of `list_array->values()`) to resolve type mismatch errors
- **Test adjustments**: Updated `BinaryRowPartitionComputerTest` to remove unsupported float/double partition fields, reducing field count from 14 to 12
- **Disabled incompatible test**: Marked `SstFileIOTest.TestJavaCompatibility` as DISABLED due to Java compatibility issues
- **Code formatting**: Applied pre-commit hooks for consistent code style across modified files
- **Catalog module reorganization**: Moved catalog-related files from `src/paimon/` to `src/paimon/core/catalog/` for better module structure
- **Test data additions**: Added comprehensive test data files for various scenarios including append tables, PK tables, blob data, file indexes, and compression tests
### Tests
- Updated unit tests in `binary_array_test.cpp`, `binary_row_partition_computer_test.cpp`, `cast_executor_test.cpp`, and `expire_snapshots_test.cpp` to reflect the fixes
- Disabled `TestJavaCompatibility` test temporarily pending Java compatibility resolution
- All existing tests pass with the applied fixes
### API and Format
No changes to public API or storage format. This is an internal fix for compilation and code formatting.
### Documentation
No documentation changes required. This is a maintenance fix.
### Generative AI tooling

Review Comment:
The invocability check and return type deduction are based on `Func` / `decltype(func())`, but `func` is a named variable (an lvalue) and the lambda later also calls it as an lvalue. This can accept callables that are only invocable on rvalues (passing the `static_assert`) and then fail to compile when invoked. Consider basing traits on `Func&` (e.g., invocable and result type) to match the actual call site semantics.

Review Comment:
Constructing a `std::function` just to detect emptiness can allocate and adds runtime overhead to every `Via` call for compatible callables. A more targeted check (e.g., only when `Func` is actually a `std::function<...>` or a function pointer) would avoid the extra allocation/copy while still catching the 'empty std::function' case.

Review Comment:
This fallback will fail for NaN cases: `target_literals[i] != result` is true for NaN, and `ASSERT_NEAR(NaN, NaN, ...)` fails. If NaN conversions are expected/possible, handle them explicitly (e.g., treat both-NaN as equal) before calling `ASSERT_NEAR`.

Review Comment:
Disabling this test without an inline reason makes it harder to track whether it should be re-enabled. Please add a brief comment explaining why it’s disabled (e.g., missing fixtures, flakiness) and ideally reference an issue/task ID for follow-up.
