Add CGO_CFLAGS="-D_LARGEFILE64_SOURCE" to resolve musl libc compatibility
issues. This enables the Large File Support feature macros which map
pread64/pwrite64/off64_t symbols (used by SQLite) to musl's native
pread/pwrite/off_t implementations.
This fix eliminates the "undeclared identifier" errors during CGO
compilation without requiring additional sqlite-dev dependencies.
