tracing: migrate opentracing-cpp → opentelemetry-cpp (API only) (#201) * tracing: migrate opentracing-cpp -> opentelemetry-cpp (API only) opentracing-cpp is deprecated/superseded by OpenTelemetry. flare ships no real tracer -- it exposes a pluggable abstraction (TracingOpsProvider / QuickerSpan / TracingOps) over the tracing-API types, with providers plugged in by users. Re-base that abstraction on the opentelemetry-cpp **API** (header-only, v1.27.0) and drop opentracing-cpp from both build systems. Scope: API only -- no SDK/exporter, so no protobuf/grpc is pulled in and the deliberately-pinned (abseil-free) protobuf 3.21.12 stays intact. The abstraction and the opaque `bytes tracing_context` wire format are kept; only the types/bodies change. Source (flare/rpc/tracing/): - tracing_ops_provider.h: re-typed virtuals; new flare-owned SpanStartOptions (parent SpanContext + SpanKind + timestamps + start attrs) replacing opentracing::StartSpanOptions/ChildOf. Extract -> std::optional<SpanContext>. - tracing_ops.h/.cc: span_ is nostd::shared_ptr<trace::Span>; SetAttribute/ AddEvent/End; SpanContext is a value type; buffered ops keep flare's owning variant and convert to (non-owning) AttributeValue only at flush. - framework_tags.h -> constexpr std::string_view; string_view_interop.h -> ToStd/ToOtel (nostd<->std). Standard-tag table is a literal allowlist; span.kind moves from a tag to SpanStartOptions::kind. - Call sites rpc_channel.cc / normal_connection_handler.cc updated; rpc_meta.proto comment updated (wire field unchanged). - Tests/benchmark rewritten onto a recording fake otel::trace::Span (OTel's noop span can't be asserted on); integration test asserts span kind via the provider-recorded "span.kind" instead of an opentracing tag. Build: - blade: BLADE_ROOT vcpkg_config gains opentelemetry-cpp; thin wrapper //thirdparty/opentelemetry-cpp:api (refs opentelemetry_common -- the api component is header-only with no .a; that lib's include dir carries the api + absl headers). opentracing thirdparty dir removed. - bazel: deps.bzl http_archive for opentelemetry-cpp 1.27.0 + api-only bazel/opentelemetry-cpp.BUILD (header-only, bundled nostd -> no abseil); patch_cmds drop the archive's nested BUILDs so the api headers can be globbed. opentracing BUILD/patch + .bazelignore/.gitattributes entries removed. Verified: blade and bazel both build //flare/rpc/tracing/... and pass tracing_ops_test + integration_test. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * ci: bazelignore thirdparty/opentelemetry-cpp (blade BUILD) The repo-wide `bazel build ...` job parses every BUILD file; the blade thin wrapper thirdparty/opentelemetry-cpp/BUILD uses blade-only syntax (vcpkg#...:lib, visibility='PUBLIC'). Add it to .bazelignore (the opentracing entry was removed but its replacement wasn't added). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * tracing: clang-format (v15) the migrated files Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * chore: drop accidentally-committed .claude/ tooling files Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * doc(tracing): note provider ABI contract for OpenTelemetry nostd types The TracingOpsProvider interface uses OpenTelemetry API types (nostd::shared_ptr<Span>, nostd::string_view, AttributeValue) directly. The nostd:: backing is a compile-time choice (bundled / std via OPENTELEMETRY_STL_VERSION / abseil) and the three are mutually incompatible types, so a provider must be built with the same OpenTelemetry configuration as flare. flare leaves the default nostd in place. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * chore: gitignore .claude/ (Claude Code local tooling) Prevents accidentally re-committing .claude/settings*.json (cf. review comments on PR #201). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * tracing: address PR #201 review follow-ups (non-blocking) - forcibly_sampled now routes `flare.sampling_priority` through the provider's `SetFrameworkTag` translation (before `IsSampled`) instead of a raw `SetAttribute`, keeping the `flare.`-prefixed tag consistent with every other framework tag and letting providers honor the force-sample signal. Add `ext::kSamplingPriority`. - An empty log key (single-arg `AddTracingLog`) now materializes as the default event name "log" so backends that group/display by event name don't render a blank one; document the per-log-event mapping. - Guard `QuickerValue`'s reliance on P0608R3 (C++20) with a static_assert so a future standard downgrade can't silently bind `const char*` to bool. - Reset `DummySpan`'s inline-static tags/logs at the start of the recording test so assertions can't observe leftovers.

thirdparty: upgrade protobuf to vcpkg 3.21.12 (last abseil-free) (#184) Migrate protobuf from vendored 3.4.1 to vcpkg 3.21.12 (last release before Abseil became mandatory). vcpkg protoc + libprotobuf; source fixes for the 3.4->3.21 API (cpp_helpers.h, duplicate ext registration, Status::ToString); remove the ~47MB vendored 3.4.1 tree. Both blade and bazel builds + proto/RPC tests pass; protobuf install is abseil-free.
