fix: show chat tool progress

[rogerchappel]

Summary

• forward OpenClaw stream: "tool" chat events from /api/chat as chat_progress SSE payloads
• include sanitized/truncated tool name/status/detail metadata so long-running tool calls surface in CrewCMD instead of silent waits
• render live tool labels such as “Calling sessions_send” / “Completed sessions_send” in the execution progress panel
• teach the active chat run store to preserve tool detail and treat tool progress events as running state

Verification

• pnpm exec eslint src/app/api/chat/route.ts src/components/chat/execution-progress-panel.tsx src/lib/chat-active-run-store.ts src/lib/chat-active-run-store.test.ts
• pnpm exec tsc --noEmit --pretty false
• pnpm test -- src/lib/chat-active-run-store.test.ts --run
• git push -u origin fix/chat-tool-activity-feedback pre-push hook ran pnpm typecheck and pnpm build successfully

Notes

• preserves normal text streaming and [DONE] handling; tool activity is sent as additional chat_progress data frames
• tool args/results are collapsed to single-line snippets and truncated to avoid dumping large raw payloads into the UI
