Document the threat model and chosen hardening approach for the OTel
pipeline: mTLS to the collector as primary defense (across-network
deployment), NetworkPolicy as defense-in-depth, and source-side
validation plus per-peer rate limiting for protocol::TraceContext on
peer messages. Skips Basic Auth (wrong shape for multi-operator
fleet) and HTTP-gateway header stripping (rippled is P2P).
Wires the new doc into the master plan ToC, mermaid diagram, and
body section, plus cross-refs from the privacy section in
02-design-decisions.md and the collector config in
05-configuration-reference.md so readers reach it from natural
in-context entry points. Adds a backlink at the top of secure-OTel.md
to the master plan.
Adds 'exfiltration' and 'htpasswd' to cspell dictionary.

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

- Add "hicpp" to cspell dictionary for NOLINT annotations
- Concatenate nested namespaces in RpcSpanNames.h
- Fix include hygiene and nested ternary in RPCHandler.cpp

Introduces task list documents for Phases 2 through 5, with Tempo
references (replacing Jaeger) and Task 2.8 dashboard parity spec.

Redesign SpanGuard with pimpl idiom to hide all OpenTelemetry types
from public headers. Add global Telemetry accessor so SpanGuard factory
methods work without explicit Telemetry references. Add child/linked
span creation and cross-thread context propagation. Update plan docs
to reflect macro removal in favor of SpanGuard factory pattern.

Throwing exceptions from code sometime confuses ASAN, as it cannot keep track of stack frames. This change therefore adds a macro to skip instrumentation around the `Throw` function.
ASAN wasn't able to keep track of `boost::coroutine` context switches, and would lead to many false positives being detected. By switching to `boost::coroutine2` and `ucontext`, ASAN is able to know about the context switches advertised by the `boost::fiber` class, which in turn leads to more cleaner ASAN analysis.
