fix(android): align nitro-fetch NDK version

[huytdps13400]

Summary

• configure the react-native-nitro-fetch Android library with the consuming root project's ndkVersion
• fall back to the existing NitroFetch_ndkVersion package property when the root does not override it
• match the configuration already used by the WebSocket and text-decoder sibling packages

Fixes #178.

Verification

The same Gradle model probe was run before and after the change:

before: NITRO_FETCH_NDK_VERSION=27.0.12077973
after:  NITRO_FETCH_NDK_VERSION=27.1.12297006

Additional checks:

• bun test — 10 passed, 2 existing TODOs
• bun typecheck
• bun lint — no errors (2 existing no-shadow warnings in unrelated Expo plugin files)
• ./gradlew :react-native-nitro-fetch:assembleDebug -PreactNativeArchitectures=arm64-v8a — successful
• generated CMake cache points to NDK 27.1.12297006
• llvm-readelf -Ws libnitrofetch.so contains no __cxa_init_primary_exception reference

Yeah thanks. Ideally this should be fixed by RN itself. I have an issue opened there. But this works for now

[huytdps13400]

That makes sense. This keeps nitro-fetch aligned with the consuming React Native project's selected NDK in the meantime, and can be revisited once the upstream RN/AGP behavior guarantees that alignment for libraries. I'll keep an eye on the upstream issue and adjust this PR if you prefer a different interim approach.

[riteshshukla04]

Ideally RN should never use NDK 27 with AGP 9. The default version is NDK 28

[huytdps13400]

Agreed. The merged change does not pin NDK 27; it delegates to the consuming root project’s ndkVersion. Once the React Native template/toolchain selects NDK 28 for AGP 9, nitro-fetch will follow that value automatically instead of compiling with a separate AGP default.
