fix: preserve symbol tables in Rust bindings for Play Store debug symbols

Rust Cargo.toml had strip=true which removes ALL symbols including the
symbol table needed by AGP to generate native-debug-symbols.zip for
Play Store. Changed to strip="debuginfo" which keeps symbol tables
(needed for crash symbolication) but removes debug info (keeps .so small).

Also made debugSymbols conditional in distribute workflow so missing
symbols don't fail the upload.
