fix: verify android elf build ids

[ovitrif]

Fixes #95

Implements the LDK producer portion of synonymdev/bitkit-android#1105. Companion PRs: synonymdev/bitkit-core#131, synonymdev/vss-rust-client-ffi#19, pubky/paykit-rs#124, and synonymdev/bitkit-android#1106.

Description

• links every published Android ABI with a SHA-1 GNU build ID while preserving the existing 16 KB page-size linker flags
• requires build-ID presence before stripping, verifies strip survival, and compares each final AAR library with its unstripped symbol counterpart
• requires full DWARF metadata in the native debug-symbol archive and makes publication depend on artifact validation
• bumps the cross-platform package to 0.7.0-rc.58 and regenerates Android, JVM, Python, and Swift artifacts

QA Notes

• cargo fmt --check
• cargo clippy --all-targets --all-features (passes with existing warnings)
• cargo test --lib --all-features — 87 passed
• cargo test --doc --all-features — 12 passed
• ./gradlew build
• ./gradlew validatePublishedNativeArtifacts publishToMavenLocal
• shellcheck scripts/uniffi_bindgen_generate_kotlin_android.sh
• NDK llvm-readelf -n independently confirmed GNU build-ID presence and packaged-to-symbol parity for armeabi-v7a, arm64-v8a, and x86_64
• the published 0.7.0-rc.58 AAR and native-debug-symbols classifier were consumed from the task-local Maven repository by the Bitkit Android release build
