Add Claude Code skill files and CLAUDE.md for Eventuous library users

[qodo-free-for-open-source-projects]

Description

• Claude Code users working with the Eventuous library lack structured, machine-readable guidance covering the library's domain model, command services, event stores, subscriptions, producers, and projections.
• Infrastructure-specific configuration details (KurrentDB, PostgreSQL, MongoDB, SQL Server, RabbitMQ, Kafka, Google Pub/Sub, Azure Service Bus, Gateway) are scattered and not easily discoverable by AI assistants.
• Contributors to the Eventuous repository need a CLAUDE.md file so Claude Code understands the build system, test framework, project layout, and code style conventions.

Deliverables

• CLAUDE.md: Add a repository-level CLAUDE.md covering build/test commands, architecture overview, project layout, docs site setup, and code style.
• Core skill file: Add skills/eventuous.md covering domain model, command services, serialization, stream naming, HTTP API, subscriptions, producers, and DI registration patterns.
• Infrastructure skill files: Add 9 infrastructure-specific skill files (eventuous-kurrentdb.md, eventuous-postgres.md, eventuous-mongodb.md, eventuous-sqlserver.md, eventuous-rabbitmq.md, eventuous-kafka.md, eventuous-google-pubsub.md, eventuous-azure-servicebus.md, eventuous-gateway.md) with full registration examples and API references.
• Progressive disclosure: Core skill file references infrastructure files so users load only what is relevant to their stack.
