Decompose handle-event.go into DDD domain services (v0.36.15)

Major refactoring of event handling into clean, testable domain services: - Add pkg/event/validation: JSON hex validation, signature verification, timestamp bounds, NIP-70 protected tag validation - Add pkg/event/authorization: Policy and ACL authorization decisions, auth challenge handling, access level determination - Add pkg/event/routing: Event router registry with ephemeral and delete handlers, kind-based dispatch - Add pkg/event/processing: Event persistence, delivery to subscribers, and post-save hooks (ACL reconfig, sync, relay groups) - Reduce handle-event.go from 783 to 296 lines (62% reduction) - Add comprehensive unit tests for all new domain services - Refactor database tests to use shared TestMain setup - Fix blossom URL test expectations (missing "/" separator) - Add go-memory-optimization skill and analysis documentation - Update DDD_ANALYSIS.md to reflect completed decomposition Files modified: - app/handle-event.go: Slim orchestrator using domain services - app/server.go: Service initialization and interface wrappers - app/handle-event-types.go: Shared types (OkHelper, result types) - pkg/event/validation/*: New validation service package - pkg/event/authorization/*: New authorization service package - pkg/event/routing/*: New routing service package - pkg/event/processing/*: New processing service package - pkg/database/*_test.go: Refactored to shared TestMain - pkg/blossom/http_test.go: Fixed URL format expectations 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
