Refactor InputMode into a proper state machine enum#76
Open
Conversation
Move key mapping and state transition logic into methods on InputMode, encapsulating behavior with the state it belongs to. Transition methods (begin_streaming, finish_streaming, await_tool_approval, resume_streaming, reset) enforce valid state changes via debug_assert, catching invalid transitions during development. Semantic helpers (is_idle, is_busy) replace raw equality checks throughout the codebase. https://claude.ai/code/session_0131MmNJi1QqvcV9w8A3TAQS
