VS Code extension 0.7.0 (agent-core-v2): TodoList card no longer shows items when expanded; context usage % frozen

Environment

• Extension: moonshot-ai.kimi-code 0.7.0 (darwin-x64)
• VS Code: 1.133.0
• OS: macOS 15.7.9
• Regression window: 0.6.x -> 0.7.0 (after the agent-core-v2 default switch, #2916)

Bug 1: TodoList tool card shows only "Todo list updated" when expanded

Before 0.7.0, expanding the "Update Todos" tool card showed the full todo list (each step with its status). After 0.7.0, the expanded card body renders only the result summary text "Todo list updated"; the todo items are no longer rendered.

Repro: in any session agent update its todo list, then expand the tool card.

Bug 2: Session context usage percentage frozen

The context usage percentage at the top of the chat window disappeared entirely for several days after the 0.7.0 update, then reappeared, but the value is now static - it never updates as the conversation grows.

Notes

#2916 states "the interface, sessions, and workflows are unchanged"; both behaviors look like undocumented UI regressions on the v2 engine path.

Reproduce both regressions in the VS Code extension 0.7.0 on the agent-core-v2 path, then compare the TodoList card and context-usage update flow with 0.6.x and the change in #2916. Done means expanded TodoList cards show each item and status, while the context percentage updates as the conversation grows.
