Atlas continuation only treated running background tasks as active work. When a delegated subagent had been launched but was still waiting for session creation, the task remained pending and Atlas could inject another continuation too early.
Treat pending tasks as active background work in the continuation injector and add regression coverage for the pending-session-creation race so delegated work is allowed to acquire a session before Atlas resumes the plan.

All 5 continuation paths now send variant as top-level body field:
- boulder-continuation-injector.ts
- ralph-loop/continuation-prompt-injector.ts
- todo-continuation-enforcer/continuation-injection.ts
- unstable-agent-babysitter-hook.ts
- session-recovery/resume.ts
Plus type/helper updates in atlas, todo-continuation-enforcer,
unstable-agent-babysitter, and session-recovery.
TDD: 18 regression tests added, all pass. tsc clean.
Update continuation injector to work with new lineage detection.
Refine idle event handling for proper subagent session tracking
and agent mismatch detection.

The agent parameter was using raw config key "atlas" but the SDK
expects the display name "Atlas (Plan Executor)". This caused
"Agent not found: 'atlas'" errors when auto-compact tried to
continue boulder execution.
Root cause: injectBoulderContinuation passed raw agent key to
session.promptAsync, but SDK's agent matching logic compares
against display names registered in the system.
Fix: Use getAgentDisplayName() to convert the config key to
the expected display name before passing to the SDK.
Apply the internal initiator marker to automated continuation, recovery, babysitter, stop-hook, and hook-message injections so Copilot attribution consistently sets x-initiator=agent for system-generated prompts.
