[Bug] --agent <name> hard-crashes in headless print mode: EventBus "agent.activity.updated has no active lifecycle context"

[NashCC1550]

Environment

• kimi-code v0.38.0 (latest), macOS arm64, installed via official install script
• Invocation: headless print mode (-p)

Reproduction

kimi --agent dev -p "hi"

Also crashes identically with a deliberately nonexistent profile name (--agent nonexistent-probe), so the crash is not dependent on profile content or discovery success.

Expected

Session starts with the named agent profile, or a clean "profile not found" error.

Actual

Hard crash before any session activity:

Error: Agent event 'agent.activity.updated' has no active lifecycle context

Notes / workaround

• --agent-file <path> works fine in print mode — the profile loads and is honored (verified with a project-local profile; the agent correctly self-reports its profile name). So the profile loading path is healthy; only the --agent <name> discovery/dispatch path crashes.
• Mirror-image issue on the other surface: TUI ignores --agent-file at launch; startup session binds default agent (works in -p print mode) #2767 (--agent-file ignored in TUI but works in -p). Together these suggest the custom-profile wiring differs between TUI and headless in two opposite ways.
• Agent profile discovery dirs observed from the binary: project .kimi-code/agents / .agents/agents, user .agents/agents. (As an aside: it would be helpful if the docs page for agents/sub-agents listed these explicitly.)
