Add Klime destination with track, identify, and group actions

[beatlevic]

Add Klime as a new Action Destination with track, identify, and group actions.

Klime is a customer analytics platform. This enables Segment customers to forward events to Klime's batch ingest API (POST /v1/batch) with Bearer token authentication and batching support (up to 100 events per request).

Actions:

• Track — forwards track events with event name, properties, userId, groupId, and context
• Identify — forwards identify events with userId, traits, and context
• Group — forwards group events with groupId, traits, userId, and context

Implementation details:

• Custom auth scheme with Bearer token via extendRequest
• testAuthentication validates the write key by sending an empty batch
• Configurable endpoint (production / development) via dropdown
• Batching enabled by default, up to 100 events per request
• Modeled after Trubrics, Spiffy, and PostHog destination patterns

Note: Registered with a placeholder metadata ID (placeholder-klime-id) — to be replaced with the real ID after destination registration in Segment.

Testing

9 unit tests covering all 3 actions (default mappings, payload structure, batch events). Tested end-to-end against live Klime dev API using ./bin/run serve --destination=klime.

• Added unit tests for new functionality
• Tested end-to-end using the local server
• [If destination is already live] Tested for backward compatibility of destination. Note: New required fields are a breaking change. — N/A, new destination
• [Segmenters] Tested in the staging environment
• [Segmenters] [If applicable for this change] Tested for regression with Hadron.

E2E test evidence

Security Review

• Reviewed all field definitions for sensitive data (API keys, tokens, passwords, client secrets) and confirmed they use type: 'password'

New Destination Checklist

• Extracted all action API versions to versioning-info.ts file. — N/A, Klime uses a fixed endpoint (/v1/batch), no versioned API.

Hi @beatlevic I reviewed the PR. However I need to clarify your identity before I deploy the code.
Can you confirm that your company is an approved Segment partner?
Can you send me an email to jayoub@twilio.com from your work address please?

Kind regards,
Joe
