  Log Message:
  -----------
  [lldb] Bound JSON object file text by buffer size (#223575)

ObjectFileJSON created a StringRef from a bare pointer without a length.
Mapped buffers lack a NULL terminator, causing strlen to read past
page-aligned mappings.

Pass the buffer size and stop at the first NULL to handle unterminated
mappings and zero-padded probe reads.
