Head sampling is fixed at 1.0 and not configurable. Remove the
sampling_ratio line and its stale tuning comment; point volume reduction
at collector-side tail sampling.

Head sampling is fixed at 1.0 and not configurable. Drop sampling_ratio
from the docker sample/test configs and the data-collection reference;
rewrite the span-metric sampling caveat and volume guidance to point at
collector-side tail sampling.

Head sampling is now fixed at 1.0 and not configurable. Drop the
sampling_ratio config row and redirect volume-reduction guidance to
collector-side tail sampling. trace_peer=0 stays as the high-volume opt-out.

The telemetry test module compiles ValidationTracker.cpp (from src/xrpld/)
into xrpl_tests and includes <xrpld/telemetry/ValidationTracker.h>. The
single-binary test scheme dropped the src/ include directory that the old
per-module target carried, breaking the build. Restore it on the telemetry
branch of the test CMakeLists.

sampling_ratio is no longer parsed (head sampling fixed at 1.0), so remove
the parse/clamp assertions and the sampling_ratio_clamped test. Update the
default-tracePeer expectations to TRUE to match the enabled-by-default change.

Document that head sampling is intentionally fixed at 100% and no longer
exposes a sampling_ratio config knob. A per-node ratio let nodes make
divergent keep/drop decisions for the same distributed trace, producing
broken/partial traces; pinning at 1.0 with a ParentBased sampler keeps
decisions coherent across the network. Volume reduction is delegated to
collector-side tail sampling.

Update the docker/telemetry sample config and testing guide to set
trace_peer=1, matching the new on-by-default behavior and the other
trace categories already enabled in these all-categories sample profiles.

Update the Peer Spans note, the known-gaps caveat, and the trace category
toggle table to show trace_peer enabled by default. The Production Setup
example keeps trace_peer=0 as a deliberate high-volume opt-out alongside
sampling_ratio=0.01.

Reflect the new on-by-default behavior in the config defaults table. The
volume-reduction guidance (High memory usage, Production mainnet tuning)
intentionally keeps trace_peer=0 as an opt-out recommendation for
high-traffic deployments.
