v0.2.0

Changed

• @boundary is now transparent: it never changes what the wrapped function returns or raises. extract_result feeds the envelope only.
• Zero-config capture binds the real signature and records arguments by their real names (skipping self). Note: recorded graph_state shape changes for some call patterns, so pre-0.2 fixtures may need re-recording.

Added

• chronicle.wrap(client): record every model call an OpenAI/Anthropic-style client makes, no decorators; replay returns the recorded response and makes no API call.
• chronicle.instrument_langgraph(nodes): wrap every LangGraph node as a @boundary in one call (async supported).
• Async support: async def boundaries record, stub, and cut-point like sync ones.
• Per-request isolation: the session is context-scoped (ContextVar).
• Failure capture: a boundary that raises records an error envelope, then re-raises.
