AI-generated code disclosure: this PR was implemented with substantial AI assistance and manually reviewed and validated. # What does this PR do? Ensures the combined libdatadog profiling artifact enables `catch_panic` for data-pipeline FFI entry points. It also adds a packaged C regression that triggers capacity overflow and verifies that the FFI returns an error instead of aborting the process. # Motivation The standalone data-pipeline FFI crate enables panic containment by default, but the combined profiling artifact disables dependency defaults and did not re-enable it. This closes [APMSP-3830](https://datadoghq.atlassian.net/browse/APMSP-3830) before the native trace exporter payload APIs ship together. # Additional Notes **Stack position: L0, current PR: [DataDog/libdatadog PR 2302](#2302 These open L0-L5 changes are not included in [libdatadog v38.0.0](https://github.com/DataDog/libdatadog/releases/tag/v38.0.0). They are planned to ship together in a single libdatadog v39 release, with the common dd-trace-rb uptake tracked by [R3 DataDog/dd-trace-rb PR 6143](DataDog/dd-trace-rb#6143). Complete expected libdatadog review and merge order for that single v39 release: | Level | libdatadog PR | Matching dd-trace-rb consumer | | --- | --- | --- | | **L0 (current)** | **[DataDog/libdatadog PR 2302](#2302 | Release prerequisite; no payload API consumer | | L1 | [DataDog/libdatadog PR 2303](#2303) | [R4 DataDog/dd-trace-rb PR 6130](DataDog/dd-trace-rb#6130) | | L2 | [DataDog/libdatadog PR 2305](#2305) | [R5 DataDog/dd-trace-rb PR 6129](DataDog/dd-trace-rb#6129) | | L3 | [DataDog/libdatadog PR 2301](#2301) | [R6 DataDog/dd-trace-rb PR 6134](DataDog/dd-trace-rb#6134) | | L4 | [DataDog/libdatadog PR 2304](#2304) | [R7 DataDog/dd-trace-rb PR 6132](DataDog/dd-trace-rb#6132) | | L5 | [DataDog/libdatadog PR 2300](#2300) | [R8 DataDog/dd-trace-rb PR 6133](DataDog/dd-trace-rb#6133) | L0-L3 are independent and can be reviewed in parallel.

[DataDog/libdatadog-rb v37 PR 65](DataDog/libdatadog-rb#65) and [DataDog/libdatadog-rb v38 PR 66](DataDog/libdatadog-rb#66) are separate ordered prerequisite releases only for [R2 DataDog/dd-trace-rb PR 6131](DataDog/dd-trace-rb#6131) and its `ForkSafeRuntime` uptake.

AI-generated code disclosure: this PR was implemented with substantial AI assistance and manually reviewed and validated. # What does this PR do? Adds an opaque per-key `meta_struct` blob setter to `TracerSpan`. Keys are validated as UTF-8, while values are copied as uninterpreted binary data. This transitional API lets consumers pass their existing per-key MessagePack blobs without changing the Rust trace model. # Motivation Native exporter consumers cannot currently populate `meta_struct`, which blocks payload parity tracked by [APMSP-3219](https://datadoghq.atlassian.net/browse/APMSP-3219). The opaque setter provides the safe first stage before the language-neutral structured-value APIs. # Additional Notes **Stack position: L1, current PR: [DataDog/libdatadog PR 2303](#2303 These open L0-L5 changes are not included in [libdatadog v38.0.0](https://github.com/DataDog/libdatadog/releases/tag/v38.0.0).

AI-generated code disclosure: this PR was implemented with substantial AI assistance and manually reviewed and validated. # What does this PR do? Adds an atomic batched FFI for complete span links, including 128-bit trace IDs, span IDs, flags, tracestate, attributes, and ordering. All borrowed input is validated and copied before insertion. # Motivation The Rust trace model supports span links, but native exporter consumers cannot populate it. This fills the span-link portion of the payload parity work tracked by [APMSP-3219](https://datadoghq.atlassian.net/browse/APMSP-3219). # Additional Notes `dropped_attributes_count` is intentionally deferred by additive commit [961044e](961044e). Neither the Agent v0.4 nor indexed V1 span-link schema defines the field, and current Datadog tracers do not produce non-zero counts.

Why?
Publish the upstream libdatadog v37.0.0 release as Ruby platform gems. This release contains the
ForkSafeRuntimeFFI required by dd-trace-rb#6131.What does this PR do?
Bumps
Libdatadog::LIB_VERSIONfrom36.0.0to37.0.0, producing gem version37.0.0.1.0. The source-build workflow installs the builder from the matching upstream tag. Rust remains at 1.87.0, so no workflow or toolchain changes are required.How to test the change?
nix develop -c bundle exec rake: 19 examples, 0 failures.Libdatadog::VERSION == "37.0.0.1.0".Additional Notes:
This is the first of two ordered packaging PRs; the second is libdatadog-rb#66. It must be merged and published with the
Buildworkflow (push: true) before the stacked v38 PR is merged; otherwisemainwould advance and the workflow could no longer publish v37.JIRA:
