docs: add Kernel data warehouse source documentation

[inkeep]

Changes

Adds documentation for the new Kernel data warehouse source connector that was implemented in PostHog/posthog#69997.

New file

• contents/docs/cdp/sources/kernel.md - Documentation for linking Kernel as a data warehouse source

What is Kernel?

Kernel is browser infrastructure for AI agents. Teams running agents on Kernel want to join agent run history (invocations, browser sessions) with their product data in PostHog.

Tables synced

• apps - Deployed browser-automation apps
• deployments - Deployment history with status and region
• invocations - Action run history with status, payload, output, and timestamps
• browsers - Cloud browser sessions (active and soft-deleted)
• profiles - Saved browser profiles (cookies, storage, auth state)

Notes

• The connector is in alpha release status (marked with beta: true frontmatter and <AlphaRelease /> snippet)
• All tables use full-refresh sync mode (incremental not yet available)
• Documentation follows the standard warehouse source template using shared snippets
