Siavash Sameni af20fa418a fix(android): bump minSdk 24 -> 26 to avoid broken __init_tcb in NDK 24 stub ...

Build #7 crashed at launch on the Pixel 6 with SIGSEGV in
__init_tcb / pthread_create called from tao::ndk_glue::create in
WryActivity.onCreate:

  #00  __init_tcb(bionic_tcb*, pthread_internal_t*)+4
  #01  pthread_create+360
  #02  std::sys::thread::unix::Thread::new
  #04  tao::platform_impl::platform::ndk_glue::create
  #05  Java_com_wzp_desktop_WryActivity_create

Tauri scaffolds build.gradle.kts with `minSdk = 24`, which makes the
tauri-cli invoke `aarch64-linux-android24-clang` as the Rust linker. That
linker transitively pulls broken static stubs from libc.a for getauxval,
__init_tcb and pthread_create — these stubs only work in statically-
linked executables because they read bionic state (__libc_auxv, TCB) that
only the libc init path sets up. In a .so loaded via dlopen they SIGSEGV
the moment anything spawns a thread.

API 26+ has the real runtime symbols and the NDK-26 linker resolves them
against libc.so instead of the static fallback. This is also the minimum
Oboe supports. Patch the generated build.gradle.kts post-init to swap
`minSdk = 24` for `minSdk = 26` — the legacy wzp-android crate solved
the same issue with a .cargo/config.toml linker override plus a
getauxval_fix.c shim.
