Summary

• Drop the Stop hook that demanded an unavailable tool. It blocked every turn end while a background subagent was alive and told the model to wait on TaskOutput, which qodercli never exposed. Turns that launched background work looped on the same explanation until interrupted, and interrupts left the state behind, so the session stayed unusable (only a new conversation helped). The CLI already feeds completion notifications back into the model's context on its own and runs a follow-up turn; removing the hook lets turns end normally. Removes subagent-hooks.ts and all wiring (buildHooks, setSubagentStateSource, SubagentRuntimeState, hasRunningSubagents).
• Correlate background task notifications by tool_use_id. The CLI reports completion with a task_id from its own registry, which shares no id space with the agentId parsed out of the Agent tool result that the block is keyed by — so the block was never released and stayed on "Running" for the rest of the conversation (and was falsely marked orphaned on switch). The notification's tool_use_id is the launching Agent call, which is already our key; prefer it, keep the agentId lookup as a fallback, and let a notification claim a block whose agentId was never parsed.

Verification

• npm run typecheck
• npm run lint
• npm run test (3611 passed)
• npm run build (renderer-safe-unref patch applied; no bare heartbeatWatchdog.unref())
• npm run release:check
• npm run audit:prod (0 vulnerabilities)
• Tested affected qodercli behavior against a real CLI when applicable — real Obsidian end-to-end with qodercli 1.1.87 + SDK 1.0.58: a background subagent turn ends normally (no loop, zero TaskOutput mentions), the card transitions Running → completed with the result, and the CLI's follow-up turn delivers it. Session jsonl confirms the notification's tool-use-id matches the launching Agent call while task-id differs.

Safety

• No credentials, private vault content, internal URLs, or personal paths are included
• User-visible changes are documented in CHANGELOG.md
