Fix directory spider tag loss: size limits and validation

- Increase WebSocket message size limit from 500KB to 10MB to prevent
  truncation of large kind 3 follow list events (8000+ follows)
- Add validation in SaveEvent to reject kind 3 events without p tags
  before storage, preventing malformed events from buggy relays
- Implement CleanupKind3WithoutPTags() to remove existing malformed
  kind 3 events at startup
- Add enhanced logging showing tag count and event ID when rejecting
  invalid kind 3 events for better observability
- Create round-trip test proving binary tag encoding preserves p tags
  correctly through JSON→binary→JSON cycle
- Root cause: 500KB limit was truncating large follow lists during
  WebSocket receive, causing tags to be lost or incomplete
- Three-layer defense: prevent at gate (size), validate (save time),
  and cleanup (startup)

Files modified:
- app/handle-websocket.go: Increase DefaultMaxMessageSize to 10MB
- pkg/database/save-event.go: Add kind 3 validation with logging
- pkg/database/cleanup-kind3.go: New cleanup function
- pkg/database/cleanup-kind3_test.go: Round-trip test
- app/main.go: Invoke cleanup at startup
