UX Regression: Can't View Session Details of Incomplete Task Call #34457

Description

I've noticed when

1. A subagent session hangs on an inner tool call and I end up needing to cancel a subagent run for some reason or
2. I close OC while a subagent was running

that incomplete subagent calls are red in the TUI and now block a user from looking into that subagent's session transcript at all. As a workaround, I have to spawn another subagent so I can arrow through to find the one that never completed and figure out where things went wrong for that subagent. This feels like a UX bug or regression introduced in v1.15.13 that is a side-effect of what it was trying to accomplish. Specifically this looks to have taken place in #28664 in commit 5fb85a6

Looking at the code, here is what I think is going on: InlineTool was refactored to fix icon alignment on wrapped rows, but as a side-effect introduced a failed guard in the onMouseUp handler:

const failed = createMemo(() => Boolean(error() && !denied()))

onMouseUp={() => {
  if (renderer.getSelection()?.getSelectedText()) return
  if (failed()) {
    setErrorExpanded((value) => !value)  // expands error text
    return                               // we now never reach onClick
  }
  props.onClick?.()
}}

So now, when a session is interrupted, processor.ts's cleanup() sets all in-flight tool parts to status: "error" with error: "Tool execution aborted". That flips failed() to true, causing clicks to toggle the error message instead of navigating into the child session.

The child sessionId is still preserved in the metadata (as interrupted: true), so the navigation could work. The click handler is just short-circuiting. I think the failed() guard needs to allow navigation if a sessionId exists, or not early-return when props.onClick is set.
