sync agent-compose proto to v2609.3.0

[yorkew-east8]

Summary

• Accept Agent Compose Token/RBAC URLs that include a path prefix, and treat api_key as an alias for api_token.
• Pin the Agent Compose protobuf snapshot to 493af1c (v2609.3.0) and regenerate Connect clients.
• Update agent-compose command wiring for Timestamp fields, ProjectRef oneof selectors, offset pagination, and renamed stream RPCs (StreamAgentRun, StartAgentRun, StreamExec).

This unblocks chaitin-cli agent-compose project ls against current daemon/UI Token API responses that previously failed with string field contains invalid UTF-8.

This CLI must be used with Agent Compose daemon v2609.3.0. Older daemons are not supported.

User-visible changes

• --url may include a path prefix.
• api_key / AGENT_COMPOSE_API_KEY are aliases of api_token / AGENT_COMPOSE_API_TOKEN.
• Pagination flags --cursor are replaced by --offset on ps, run events, scheduler runs, and scheduler logs.
• JSON continuation field next_cursor is now next_offset (uint).
• Streaming JSON event_type prefixes changed:
  • run_agent_stream_event_type_* -> stream_agent_run_event_type_*
  • exec_stream_event_type_* -> stream_exec_event_type_*
• Timestamp fields are formatted by the CLI instead of being echoed as raw proto strings.

Config

agent-compose:
  url: http://127.0.0.1:8081
  api_token: YOUR_API_TOKEN
  default_project: optional-project

api_key remains accepted as an alias. Environment overrides:
AGENT_COMPOSE_URL, AGENT_COMPOSE_API_TOKEN (or AGENT_COMPOSE_API_KEY), AGENT_COMPOSE_DEFAULT_PROJECT.

Example

chaitin-cli agent-compose --url http://127.0.0.1:8081 project ls
chaitin-cli agent-compose --url http://127.0.0.1:8081 --project my-project agent ls
