build: keep CMake and Meson definitions in sync

[Sakshamm-Goyal]

Summary

• install the missing public headers in Meson and the top-level catalog headers in CMake
• include snapshot_summary_builder_test.cc in Meson's table_test
• align the CRoaring, nlohmann/json, and GoogleTest fallback versions across CMake and Meson
• add a dependency-free parity regression and run it in CI

Closes #894.

Validation

• python3 dev/test_build_definition_parity.py
• pre-commit run --files .github/workflows/test.yml cmake_modules/IcebergThirdpartyToolchain.cmake src/iceberg/catalog/CMakeLists.txt src/iceberg/catalog/rest/auth/meson.build src/iceberg/meson.build src/iceberg/test/meson.build dev/test_build_definition_parity.py
• CMake configure with bundle/REST disabled, followed by cmake --build build-cmake-parity --target table_test --parallel 2
• ctest --test-dir build-cmake-parity -R '^table_test$' --output-on-failure
• Meson configure with REST/tests enabled, followed by meson compile -C build-meson-parity table_test -j 2
• meson test -C build-meson-parity table_test --print-errorlogs
• inspected both generated install manifests for the corrected public headers

AI assistance disclosure

AI-assisted tooling was used for initial regression-test scaffolding and mechanical build-definition edits. I reviewed the change end-to-end, verified the dependency choices and generated manifests, and ran the validations listed above. I am not aware of remaining uncertainty in the affected build paths.

The failing Ubuntu Debug and macOS Build Example steps were caused by CRoaring 4.3.11 exposing roaring-headers and roaring-headers-cpp in the vendored target install interface. Iceberg exports roaring without exporting those build-only helper targets, so downstream find_package(iceberg) marked the package not found.

I pushed 09fabab to keep both helper targets behind BUILD_INTERFACE and added parity coverage for the export invariant. Validation completed locally:

• build-definition parity: 4/4 passed
• repository pre-commit on the changed files: passed
• real Debug CMake build + install: passed
• installed targets contain no roaring-headers references
• downstream example/ configure and build against the installed package: passed

Replacement CI is now running on the updated head.

@Sakshamm-Goyal Thanks for the PR! I opened #894 to track current status and initiated a discussion on how we can maintain and sync the build tools in the long term. Before taking actions, we'd better gather feedbacks from the community, especially from meson maintainers like @WillAyd. Meanwhile, there are prerequisite issues like #256 we need to resolve first.
