fix(plan): prevent "Continue here" popup from repeating

[kagura-agent]

Problem

When using plan mode, after the agent calls plan_exit and presents the "Ready to implement?" prompt, selecting "Continue here" causes the popup to appear again repeatedly (fixes #9144).

Root Cause

shouldAskPlanFollowup checks whether any assistant message after the last user message contains a completed plan_exit tool call. However, it does not account for the case where "Continue here" has already been selected — the injected synthetic user message (with agent: "code") should signal that the plan-to-code transition already happened.

Fix

Added a guard in shouldAskPlanFollowup: if the last user message's agent is not "plan", skip the follow-up prompt. When "Continue here" injects a user message with agent: "code", subsequent loop iterations will no longer trigger the popup.

Changes

• packages/opencode/src/kilocode/session/prompt.ts: Added agent check in shouldAskPlanFollowup
• packages/opencode/test/kilocode/plan-exit-detection.test.ts: Added test verifying no re-trigger after "Continue here"
• .changeset/fix-plan-exit-repeat.md: Patch changeset

Testing

• Added unit test: seeds a plan session with plan_exit, then injects a "Continue here" user message with agent: "code", and asserts shouldAskPlanFollowup returns false
• Existing tests continue to pass (plan_exit detection, continue flow, dismiss, etc.)
