Bring the 5 telemetry files introduced on this branch to the enforced
house Doxygen style (/** alone, ' * ' continuation prefix, no single-line
blocks) so the check-doxygen-style hook passes under CI's --all-files run.
Comment-only: code is byte-identical after comment stripping (verified).
Also regenerate levelization results: the committed ordering.txt carried
stale 'xrpl.telemetry > xrpld.consensus/rpc' edges that the current include
graph no longer produces.

detached() strips the thread-local OTel Scope so a guard can be safely
moved to and destroyed on another thread; it pops the Scope on the origin
thread and moves the span into a scope-less guard. rootSpan() starts a span
as a fresh trace root (kIsRootSpanKey) so inbound entry points never inherit
an ambient span left active on the thread.
Impl now holds an optional<Scope> (nullopt for detached guards). Updated the
SpanGuard class docs and docs/build/telemetry.md with the cross-thread rules.
The unit test lands on phase2 where the telemetry test module exists.

libstdc++ ships <format> starting with gcc-13, so std::format in
SpanGuard::span() fails to compile on gcc-12. Build the "<prefix>.<name>"
span name via std::string::append instead and drop the <format> include.

Resolve the doCommand error-path span suffix and command attribute against
the handler registry instead of using raw request input. A recognized command
yields its canonical handler name; anything else (unregistered command, or
neither command/method present) collapses to the literal "unknown". This bounds
telemetry cardinality to the finite set of handler names plus "unknown" while
preserving per-command error attribution for known-but-rejected commands
(e.g. a submit that hit rpcTOO_BUSY stays rpc.command.submit). The command
attribute is promoted to a Prometheus label by the spanmetrics connector, so
attacker-controlled input previously enabled unbounded label cardinality.
Also add the missing LCOV_EXCL_STOP in the first SpanGuard::linkedSpan overload
so its coverage exclusion no longer bleeds into the second overload's guards.
