Yaya48andClaude Opus 5.5 bef2c8cf02 StarletBootstrapProbe: print the SBR1 ring with --sbr1-record
The probe printed the ring's length only. StarOS's EXP-003 images put
lines in the ring that REV_TRACE has no room for (the MEM2 monitor, the
measurements), so under Dolphin nothing showed them. After the record's
summary, --sbr1-record now prints the ring's text between "SBR1 RING
BEGIN" and "SBR1 RING END" on stderr, as StarOS's Broadway loader prints
it over the Gecko on the console: at most the ring's 4032 bytes, a byte
outside printable ASCII and newline, and the backslash, written \xHH.

The formatting is in ProbeRing.h, tested by StarletProbeRingTest.
