chore(deps): bump libdatadog to 0a70516

[duncanista]

Summary

Bumps the libdd-* git revs in this workspace from d7eef803 to 0a70516d66314efdd7115644b0da4b3b3e0958e0 (current tip of libdatadog main).

No code changes are required. The previous pin d7eef803... is itself the libdatadog commit feat: add Hash trait to TracerMetadata (#1931), so the workspace was already past the v32.0.0 breaking changes (capability-traits HTTP architecture from #1555 and the TracerMetadata derive removal that #1922/#1931 reversed). The HTTP-trait migration was absorbed in an earlier libdatadog bump — see crates/datadog-trace-agent/src/trace_flusher.rs, where ProxyHttpClient already implements HttpClientTrait and coalesced_traces.send(&http_client) is called against it.

What changed and why

Updated libdd-* revs to 0a70516 in:

• crates/datadog-serverless-compat/Cargo.toml
• crates/datadog-metrics-collector/Cargo.toml
• crates/datadog-trace-agent/Cargo.toml
• crates/datadog-agent-config/Cargo.toml
• Cargo.lock (regenerated via cargo update --workspace)

Range covered by this bump

d7eef803..0a70516 is ~10 libdatadog commits — none of them break this workspace's public surface. Notable items:

• 53c8c16 feat(http-client): add knob to disable connection pooling (#1933) — libdd-common gains an opt-in setting; this workspace doesn't need it (existing pool behavior is unchanged).
• 27aa92c feat(libdd-trace-utils): check for empty value in header datadog-client-computed-stats — defensive parsing change; transparent to callers.
• b1b58fc feat(telemetry): add session id support to trace export — additive on the telemetry surface; no impact here.
• 5db2a80 feat(ffe)!: remove extra_logging — feature-flag-engine breaking change; this workspace doesn't depend on libdd-ffe.
• Several sidecar / tracer-flare / FFI commits that don't touch the crates this workspace pulls in.

Companion PR

DataDog/datadog-lambda-extension#1218 bumps bottlecap to the same SHA. Bottlecap did require code changes — it had not yet adopted the v32 HttpClientTrait architecture and was on a much older libdatadog SHA (c8121f42), so the bump there spans the v32.0.0 breaking changes that this workspace already absorbed.

Test plan

• cargo check --workspace --all-targets
• cargo clippy --workspace --all-targets
• cargo test -p datadog-trace-agent stats_concentrator — both existing tests pass
• cargo fmt --all -- --check

DataDog/libdatadog@d7eef80 -> DataDog/libdatadog@989e11a is a downgrade.

Pull request overview

Updates this workspace to libdatadog v32.0.0 (new libdd-* git rev) and adapts datadog-trace-agent stats concentrator storage to account for TracerMetadata no longer implementing Eq/Hash.

Changes:

• Bump libdd-* git dependencies across crates to 989e11a2bfe68ae669493d726262c424e2cc04a9 and refresh Cargo.lock.
• Replace HashMap<Arc<TracerMetadata>, SpanConcentrator> with a hashable projected key (ConcentratorKey) and store the original Arc<TracerMetadata> alongside the concentrator for payload construction.
