The OTel naming check (Rule F) scans @code doc-comment examples and fails
on string-literal span names; Rule H warns on undefined SpanNames
constants. Replace the literal "subtask" and the undefined
rpc_span::op::dispatch with the defined rpc_span::op::process constant so
the examples model correct API usage.

OTel distinguishes a span's own context from the thread's
current/ambient context; SpanGuard is unscoped so spanContext()
(own span, default) is what cross-thread childSpan parenting needs,
and threadLocalContext() (static) snapshots RuntimeContext::GetCurrent()
for propagation. Renames captureContext.

The generator's doc said it was 'dormant, caller lands on a later branch'.
Reworded to branch-agnostic language: hashSpan() is the primary caller that
forces the root branch to mint deterministic trace roots.

Add a custom OTel IdGenerator that returns a thread-local pending trace_id on
the SDK no-parent (root) branch and a random one otherwise, plus a PendingTraceId
RAII guard that pins that id for the next forced-root span and asserts on
destruction that it was consumed. Wire the generator into
TracerProviderFactory::Create via its 4-arg overload.
This lets hash-derived spans become true trace roots so they line up into one
trace across nodes. It is installed but dormant on this branch: the caller
(hashSpan) arrives on a later branch (phase-3). GenerateSpanId is always random
and is_random_ is false so the W3C random-trace-id flag is not set on
deterministic ids.

Separate the two responsibilities the old SpanGuard fused: span ownership
(thread-free) and scope activation (thread-bound TLS push).
- SpanGuard now owns ONLY the span. Its Impl drops the optional<Scope>,
the owner thread-id, the Detached tag and the scope-less ctor; ~Impl is
just `if (span) span->End()`. The guard never binds a thread-local
context stack, so it may be moved to and destroyed on any thread.
- ScopedSpanGuard is a new pimpl type that wraps a SpanGuard plus an
optional<Scope>. Member order (guard first, scope second) pops the
scope before the span ends. It is non-copyable and non-movable;
factories return unnamed temporaries so guaranteed copy elision covers
`auto s = ScopedSpanGuard::freshRoot(...)`.
- `operator SpanGuard() &&` replaces detached()/detachInPlace(): it pops
the scope eagerly on the origin thread and yields a thread-free
SpanGuard for handoff to a job or another thread. detached(),
detachInPlace() (both overloads) and the Detached apparatus are deleted.
- Move-assignment is re-enabled on SpanGuard (no Scope to re-bind), in
both the real class and the no-op stub.
- rootSpan() renamed to freshRoot() in both classes (behavior unchanged:
still forces kIsRootSpanKey).
- hashSpan behavior is intentionally unchanged (only builds the now
unscoped Impl); the true-root IdGenerator fix is a separate later task.

Add two free functions in xrpl::telemetry that wrap the required
"detach a live SpanGuard held in a container" idiom so call sites write
one line instead of the make_shared/emplace rebuild by hand:
void detachInPlace(std::optional<SpanGuard>&);
std::shared_ptr<SpanGuard> detachInPlace(std::shared_ptr<SpanGuard>);
Both are no-ops on an empty/null/inactive guard. The #else branch adds
matching inline no-op stubs so callers compile with telemetry disabled.
Pure API addition, no behavior change; consumer call sites are rewritten
on phase4 in a follow-up.
The unit tests for these helpers land on phase2, where the telemetry
test module (in-memory-exporter harness + SpanGuardScope.cpp) exists —
mirroring how the detached()/rootSpan() tests were placed.

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.

The otel-naming Rule F check scans @code doc examples as call sites; raw
string literals there trip the rule. Reference *SpanNames.h constants /
placeholder identifiers in the examples so comments follow the naming rules.

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.
