Pull request overview
Adds a new usermessage package that defines and validates a v1 JSON wire contract for fetching resolved in-app user messages, along with embedded fixtures and compatibility/validation tests.
Changes:
- Introduces v1 request/response/message/action types with explicit wire-size limits.
- Adds validation for request, response, resolved message content, and allowlisted actions (including HTTPS URL validation).
- Adds versioned embedded JSON fixtures and tests covering round-trip JSON compatibility and validation rules.

Enforce action capability negotiation during response validation.
UserMessageResponse.Validate only calls ResolvedUserMessage.Validate, so it accepts ActionTypeOpenHTTPSURL when the request's ClientCapabilities.Actions is empty. A caller that uses this validator as its response gate can send an action the requesting client cannot handle. Add request-aware response validation or enforce this action intersection at every response producer, with a mismatch test.
