Fix Peek::as_str() for double references (&&str)

Previously, Peek::as_str() would cause undefined behavior when
attempting to read &&str as if it were a direct pointer. The issue
was that the function was trying to read &&str as &str directly,
resulting in SIGSEGV.

The fix adds proper handling of nested references by:
1. First checking if we have a nested reference (&&str)
2. For &&str, dereferencing twice to get to the inner &str
3. For &str, handling the simple case

Added regression test for issue #794.
