Update OpenTelemetryPlan docs and Telemetry.h doc example to reflect
the renamed per-span attributes: xrpl.rpc.command -> command,
xrpl.rpc.status -> rpc_status, xrpl.grpc.method -> method, etc.

- Drop xrpl.pathfind.* prefix from per-span attrs (source_account,
dest_account, fast, search_level, num_complete_paths, num_paths,
num_requests).
- Keep xrpl.pathfind.ledger_index qualified (rule 5: distinct from
xrpl.ledger.seq).
- Remove per-span nodeAmendmentBlocked/nodeServerState calls from
RPCHandler — promoted to resource-level attrs.
- Mark node-health attrs in SpanNames.h as RESOURCE-ONLY with doc.

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

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.

Mark local variables in extractFromProtobuf() and injectToProtobuf()
as const since they are not modified after initialization: traceId,
spanId, flags, spanCtx, and span.

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

- Restore over-renamed values: rippledb, rippled.cfg, historical GitHub URL
- Concatenate nested namespaces in SpanNames.h and PathFindSpanNames.h
(modernize-concat-nested-namespaces)
- Add missing includes and const qualifiers in test files
- Suppress intentional use-after-move in SpanGuardFactory move test
- Remove unused NetworkOPs.h include from PathRequest.cpp

Use C++17 concatenated namespaces, add [[nodiscard]] to query methods,
add missing direct includes, and use pass-by-value + std::move in
NullTelemetry constructor.

SpanNames.h (attr::nodeAmendmentBlocked, attr::nodeServerState)
- Add Tempo search filters for node health attributes
- Remove unnecessary .c_str() on strOperatingMode() return
- Add samplingRatio clamping test (values > 1.0 and < 0.0)
- Fix Task 2.3 status: delivered in Phase 1c, not Phase 2

Centralise scattered string literals into compile-time constants using
StaticStr<N> and join() for dot-separated composition. Shared primitives
live in SpanNames.h; RPC-specific names in RpcSpanNames.h. Future modules
(consensus, peer, ledger) add their own *SpanNames.h without bloating
the central header.

- Concatenate nested namespaces (modernize-concat-nested-namespaces)
- Add [[nodiscard]] to factory and accessor methods
- NOLINT no-op stub instance methods that must stay non-static for API
parity with the real implementation

Remove the single-arg span(name) factory that creates unconditional
spans without category gating. All call sites use the 3-arg
span(TraceCategory, prefix, name) variant which checks whether the
category is enabled in config before creating a span. The 1-arg form
was dead code with no callers.

Replace rpcSpan(), txSpan(), consensusSpan(), peerSpan(), ledgerSpan()
with a single span(TraceCategory, prefix, name) factory method. Adding
a new traceable subsystem now requires only a new enum value and one
switch case — no new methods or header changes.

- SpanContext::isValid(): add inline no-op when XRPL_ENABLE_TELEMETRY
is not defined, preventing a linker error if called in that path
- linkedSpan(): set kIsRootSpanKey on the StartSpanOptions parent
context so linked spans start a genuinely independent sub-tree
instead of silently becoming children of the current active span
- Telemetry::instance_: use std::atomic with acquire/release ordering
to avoid a data race between start()/stop() and factory methods
called from worker threads
