Add Identity service implementation (RFC 8621 Section 6)

[i11v]

Summary

Implements the JMAP Identity service according to RFC 8621 Section 6, enabling clients to manage email identities (sender addresses, signatures, reply-to addresses, etc.).

Key Changes

• New Identity Schema (src/identity/schema.ts): Comprehensive schema definitions for all Identity operations including:

  • IdentityObject: Core identity data structure with email, name, signatures, reply-to, and bcc fields
  • IdentityMutable: Creatable/updatable identity properties
  • Request/response schemas for Identity/get, Identity/set, and Identity/changes methods
  • Helper functions for checking identity capabilities (canDelete, hasReplyTo, hasBcc, hasSignatures)

• New Identity Service (src/identity/service.ts): Effect-based service implementation providing:

  • get(): Retrieve identities by ID
  • set(): Create, update, or destroy identities
  • changes(): Track identity changes since a state
  • getAll(): Convenience method to fetch all identities for an account
  • getDefault(): Convenience method to get the first/default identity
  • Full error handling with proper error types (JMAPMethodError, NetworkError, AuthenticationError, SessionError)

• Client Integration (src/client/wrapper.ts): Added IdentityNamespace to the promise-based wrapper with all service methods exposed as async functions

• Layer Configuration (src/layers.ts): Integrated IdentityServiceLive into the dependency injection layer

• Public API (src/identity/index.ts, src/index.ts): Exported all Identity types and service interfaces

• Test Configuration (tests/config/capabilities.ts): Enabled Identity capability flags for testing

Implementation Details

• Follows the same architectural pattern as existing services (Mailbox, Email, EmailSubmission)
• Properly handles nullable fields per RFC 8621 (replyTo, bcc, and response fields)
• Uses Effect for composable, type-safe async operations
• Integrates with existing JMAP client infrastructure (batch requests, capability checking, response extraction)
• Includes comprehensive JSDoc comments referencing RFC 8621 specifications
