uuid cannot initialize from list on gcc with boost 1.86

The fix is

boost::uuids::uuid svc_uuid = {{0x25, 0xbb, 0x0b, 0x62, 0x86, 0x1a, 0x49, 0x74,
                                                   0xa1, 0xb8, 0x18, 0xed, 0x54, 0x95, 0xaa, 0x07}};

(use double braces.)

This has always been the "correct" way to initialize uuid, and the single braces version happened to work due to the brace elision rules because uuid was a simple struct. This is no longer the case after the 1.86 changes.

I tried hard to keep all existing valid uses working, but that's basically impossible once any nontrivial changes are made.

Interesting. I see the change now in the documentation between 1.85 and 1.86. Version 1.85 had single brackets.
