Drop the --prompt/-p flag entirely. Non-interactive mode is now
triggered by passing positional arguments:
kit "Explain this"
kit @file.go "Review this" --json
kit @a.go @b.go --quiet
Updated extension examples (kit-kit.go, subagent-widget.go) to pass
the prompt as a positional arg. Updated AGENTS.md and README.md.
Add a --json flag that outputs structured JSON (response, model, usage,
messages with typed parts) when used with --prompt. Update kit-kit and
subagent-widget extensions to use --json for cleaner subprocess output
parsing instead of raw text heuristics.
Port of Pi Pi (meta-agent with parallel expert subprocesses) to Kit's
extension system. Includes expert grid widget, query_experts tool,
custom footer, tool renderer, and orchestrator system prompt injection.
Also updates AGENTS.md with Yaegi gotchas, BubbleTea patterns, testing
recipes, and extension architecture notes.
Fixes golangci-lint issues: modernize min/max in overlay.go, replace
deprecated GetExtRunner() with new GetExtensionContext() SDK method,
remove broken --model flag from expert subprocess.
