New structs: - A2A.AuthenticationInfo (scheme, credentials) - A2A.AgentExtension (uri, description, required, params) - A2A.AgentCardSignature (protected, signature, header) - A2A.TaskPushNotificationConfig (tenant, id, task_id, url, token, authentication) - A2A.SendMessageConfiguration (accepted_output_modes, task_push_notification_config, history_length, return_immediately) Updated structs (additive only): - AgentCard: +signatures, +security_requirements - AgentCard skill type: +examples, +input_modes, +output_modes, +security_requirements - AgentCard capabilities: +extensions (repeated AgentExtension) - AgentCard supported_interface: +tenant - Message: extensions changed from map to list (per proto repeated string), +reference_task_ids - Artifact: +extensions (repeated string) - Part.Text/File/Data: +media_type, +filename JSON codec updates: - Encode/decode all new fields - Support v1.0 flat Part format (raw/url without file wrapper) in decoding - Encode/decode new structs (AuthenticationInfo, TaskPushNotificationConfig, SendMessageConfiguration, AgentExtension, AgentCardSignature) - Skill encode/decode includes examples, inputModes, outputModes, securityRequirements All changes verified against a2a.proto HEAD. No breaking changes. Part of actioncard#13
38 new tests covering: - AuthenticationInfo encode/decode - AgentExtension encode/decode - AgentCardSignature encode/decode - TaskPushNotificationConfig encode/decode - SendMessageConfiguration encode/decode - Message reference_task_ids and list extensions - Artifact extensions - Part media_type and filename on all part types - v1.0 flat Part format (raw/url) decoding - AgentCard signatures, security_requirements - AgentCard skill v1.0 fields (examples, input/output modes) - AgentCard capabilities extensions (AgentExtension) - AgentCard interface tenant field - TaskState enum round-trip for all 9 states - Backward compatibility with v0.3 format
