Support OpenTelemetry logs SDK constructor changes

[petyosi]

Summary

Support both BatchLogRecordProcessor constructor shapes from @opentelemetry/sdk-logs.

OpenTelemetry SDK logs 0.220.0 changed the processor constructor from the legacy (exporter, config?) form to an options object containing exporter. @pydantic/logfire-node already allows a broad experimental SDK logs peer range, so this keeps current 0.219.x installs working while allowing consumers to resolve 0.220.x once it clears the minimum release age policy.

Changes

• Add a small constructor compatibility helper for Logfire's logs exporter processor.
• Add tests covering both the options-object and legacy constructor shapes.
• Add a patch changeset for @pydantic/logfire-node.

Validation

• vp run @pydantic/logfire-node#test
• vp run @pydantic/logfire-node#typecheck
• pnpm run format-check
• Push hook package build/test suite

📝 Walkthrough

Walkthrough

Changes

This change adds makeBatchLogRecordProcessor in logsExporter.ts to construct BatchLogRecordProcessor through the newer options-object form and fall back to the legacy positional form when needed. logfireLogRecordProcessor() now uses that helper. Tests mock @opentelemetry/sdk-logs to verify both constructor shapes, and a changeset records a patch release for @pydantic/logfire-node.

Poem:
A log processor met two forms one day,
An options object, or the old display.
It checked, then chose the path to take,
With tests and changeset in its wake.
