v0.5.0 — Integration & Rerun Reliability

What's New

watch_compiled() — no more "must call before compile()" trap

app = graph.compile(checkpointer=memory)
app = watcher.watch_compiled(app)  # works on already-compiled graphs

Reducer-aware state merging

List fields (messages, tool calls) now append correctly during reruns instead of being silently overwritten.

HTTP recording for deterministic reruns

watcher = ArgusWatcher(record_http=True)

Records all API calls. During rerun, the same responses are served back — zero extra cost, fully reproducible.

"Replay" → "Rerun" everywhere

Honest naming across CLI, UI, docs, and guide. External API calls execute live unless HTTP recording is enabled — and now we tell you that upfront.
