- Add cons_span::event namespace with disputeResolve and txIncluded
constants; replace hardcoded strings in Consensus.h and RCLConsensus.cpp

checkValidation timing, not just message parsing

The 4-arg hashSpan overload was duplicated during a prior rebase
cascade — it appeared at both line 240 and line 305 in SpanGuard.cpp.
This would cause a linker error (multiple definition).

Record the close time voting threshold and consensus state on
consensus.update_positions and consensus.check spans:
- xrpl.consensus.close_time_threshold: the avCT_CONSENSUS_PCT (75%)
threshold required for close time agreement
- xrpl.consensus.have_close_time_consensus: whether validators
reached close time consensus in this iteration
These attributes enable dashboards to show how the close time
voting process converges (or stalls) across consensus iterations.

Remove the span-replacement logic in startRoundTracing() that was
discarding the hash-derived round span and replacing it with a linked
span (which gets a random trace_id). The deterministic trace_id from
the ledger hash is the key feature enabling cross-node correlation —
replacing it broke correlation on all rounds after the first.
Also: use thread_local mt19937 for hashSpan() span IDs (same fix as
phase-3 txSpan), add Doxygen to establish tracing method declarations
in Consensus.h, and update SpanGuard.h diagram with hashSpan/addEvent.

Instrument the consensus subsystem with OpenTelemetry spans covering
the full round lifecycle: round start, establish phase, proposal send,
ledger close, position updates, consensus check, accept, validation
send, and mode changes.
Key design choices adapted from the original Phase 4 implementation
to the new SpanGuard factory pattern introduced in Phase 3:
- Add SpanGuard::hashSpan() for category-gated hash-derived trace IDs
(consensus round spans share trace_id across validators via ledger hash)
- Add SpanGuard::addEvent() overload with key-value attribute pairs
(used for dispute.resolve events during position updates)
- Add ConsensusSpanNames.h with compile-time span name constants
following the colocated *SpanNames.h pattern from Phase 3
- Add consensusTraceStrategy config option ("deterministic"/"attribute")
for cross-node trace correlation strategy selection
- Use SpanGuard::linkedSpan() for follows-from relationships between
consecutive rounds and cross-thread validation spans
- Use SpanGuard::captureContext() for thread-safe context propagation
from consensus thread to jtACCEPT worker thread
Spans produced: consensus.round, consensus.proposal.send,
consensus.ledger_close, consensus.establish, consensus.update_positions,
consensus.check, consensus.accept, consensus.accept.apply,
consensus.validation.send, consensus.mode_change

Wire trace context into P2P message flow so distributed traces
link across nodes. TX relay injects SpanGuard context via
PropagationHelpers.h; consensus propose/validate injects via
TraceContextPropagator.h. Receive-side extraction in PeerImp
creates child spans for proposals and validations.
- Add TraceBytes struct and SpanGuard::getTraceBytes() for
extracting raw trace context without OTel type dependencies
- Add PropagationHelpers.h: injectSpanContext(SpanGuard, proto)
- Add ConsensusReceiveTracing.h: proposalReceiveSpan(),
validationReceiveSpan() with parent context extraction
- NetworkOPs::apply(): inject tx.process context before relay
- RCLConsensus::propose()/validate(): inject active span context
- PeerImp: create receive spans for proposals and validations
with sender's trace context as parent

- tx.receive span in PeerImp: convert to shared_ptr, capture in
checkTransaction lambda so it measures actual processing, not just
message parsing
- tx.process span in NetworkOPs: convert to shared_ptr, store in
TransactionStatus so it lives until the batch job processes the entry;
sync path unchanged (span destructs on function return)

Replace SpanGuard::txSpan(prefix, name, hash) with the generic
SpanGuard::hashSpan(TraceCategory, name, hash) that accepts a
TraceCategory parameter instead of hardcoding Transactions. This
enables reuse for consensus round spans (Phase 4) and any future
subsystem needing deterministic cross-node trace correlation via
hash-derived trace IDs.
Both overloads are replaced:
- hashSpan(cat, name, hash, size) — standalone with random span_id
- hashSpan(cat, name, hash, size, parentSpanId, parentSize, flags)
— with remote parent from protobuf context propagation
Add full span name constants (tx_span::receive, tx_span::process)
to TxSpanNames.h following the ConsensusSpanNames.h pattern.

Replace thread_local mt19937 with xrpl::default_prng() for span ID
generation — uses the project's existing thread-local xor-shift engine.
One call yields a uint64_t (8 bytes), filling the span ID in a single
memcpy without loops.
Fix compilation failure when XRPL_ENABLE_TELEMETRY is not defined:
move xrpl.pb.h include outside the #ifdef guard in TxTracing.h since
protocol::TMTransaction is used unconditionally in the function
signature.

Replace per-call std::random_device with thread_local std::mt19937 in
txSpan() for span ID generation. random_device is ~423x slower due to
/dev/urandom syscalls on each construction; mt19937 is seeded once per
thread and reused for all subsequent span IDs.
Update the SpanGuard class ASCII diagram to include txSpan factory
methods that were added in the hash-derived trace ID commit.

Derive trace_id from txHash[0:16] so all nodes handling the same
transaction produce spans under the same trace. Protobuf span_id
propagation provides parent-child relay ordering when available.
- Add SpanGuard::txSpan() factory methods (hash-derived trace ID)
- Add TxTracing.h helpers: txReceiveSpan(), txProcessSpan()
- Update PeerImp and NetworkOPs to use the new helpers

Move scattered string literals from PeerImp.cpp and NetworkOPs.cpp into
compile-time constants in src/xrpld/telemetry/TxSpanNames.h. Follows
the same StaticStr/join() pattern established in Phase 1c for RPC spans.
Constants cover: span prefixes (tx), operations (receive, process),
attribute keys (hash, local, path, suppressed, status, peerId,
peerVersion), and values (sync, async, knownBad).
