pi-subagents v0.20.0

Added

• Added a packaged /parallel-cleanup prompt for focused cleanup review passes.

Changed

• Consolidated the oracle-executor role into worker: worker now uses openai-codex/gpt-5.3-codex with high thinking and stricter approved-direction guardrails, while researcher and context-builder now use medium thinking.
• Updated the bundled scout agent model/thinking defaults.
• Hard-cut over grouped intercom bridge result delivery: with the bridge active, parent-side pi-subagents emits one grouped subagent:result-intercom message per foreground parent run (single, top-level parallel, or chain) and one per completed async result file. Acknowledged foreground delivery returns a compact receipt instead of duplicating full output in the normal tool result; unacknowledged delivery preserves the normal full output. Grouped messages include child intercom targets and full child summaries.

Fixed

• Fixed status and manager row rendering so multiline or tabbed content cannot overflow table rows.

Removed

• Removed the bundled oracle-executor agent and /oracle-executor prompt template in favor of using worker for approved oracle handoffs.
