Function patch_seq_file_slurp 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn patch_seq_file_slurp(stack: Stack) -> Stack

Read entire file contents as a string

Stack effect: ( String – String Bool )

Takes a file path, attempts to read the entire file. Returns (contents true) on success, or (“” false) on failure. Errors are values, not crashes. Panics only for internal bugs (wrong stack type).

Safety

• stack must be a valid, non-null stack pointer with a String value on top
• Caller must ensure stack is not concurrently modified
