What problem does this PR solve?

Issue Number: close #4889

This PR upgrades go.opentelemetry.io/otel/sdk from v1.24.0 to v1.43.0 to address upstream OpenTelemetry SDK PATH hijacking vulnerabilities:

• CVE-2026-24051 / GHSA-9h8m-3fm2-qjrq: arbitrary code execution via PATH hijacking.
• CVE-2026-39883 / GHSA-hfvc-g4fc-pqhx: incomplete BSD/Solaris kenv fix in the earlier patched versions; v1.43.0 is the first patched version for this follow-up advisory.

What is changed and how it works?

This PR updates the OpenTelemetry SDK and matching OpenTelemetry modules used by the Go module graph:

• go.opentelemetry.io/otel/sdk: v1.24.0 -> v1.43.0
• go.opentelemetry.io/otel: v1.24.0 -> v1.43.0
• go.opentelemetry.io/otel/metric: v1.24.0 -> v1.43.0

• golang.org/x/sys: v0.35.0 -> v0.42.0

go mod tidy also adds go.opentelemetry.io/auto/sdk v1.2.1 as an indirect dependency.
