Problem Summary:

```cpp
static const std::string no_message = "";
return ok() ? no_message : state_->msg;
```
In the clang-built Doris BE binary, this inline static `std::string` is
emitted as a weak/COMDAT object and placed in `.data.rel.ro`.
```bash
$ readelf -sW "$BIN" | c++filt | grep 'Status::message.*no_message'
105229: 000000007d6958e0    32 OBJECT  WEAK   DEFAULT   28 arrow::Status::message[abi:cxx11]() const::no_message[abi:cxx11]

$ readelf -SW doris/output/be/lib/doris_be | grep '\[ *28\]'
[28] .data.rel.ro      PROGBITS        000000007d0f7720 7d0f6720 7e4208 00  WA  0   0 32
```
After relocation, RELRO makes this section read-only. However, C++
function-local statics are lazily initialized on first execution, so the
first call to `Status::message()` tries to construct `no_message` at
runtime. The `std::string` constructor writes to the object storage in
`.data.rel.ro`, which triggers `SIGSEGV invalid permissions for mapped
object` like:

Move the empty message/detail sentinels out of the header inline path
and make non-OK statuses return `state_->msg` directly. This avoids
touching the empty OK-message sentinel on error paths and prevents the
inline weak/COMDAT `std::string` object from being lazily constructed
from a read-only mapping.
