fix(chat): stop orphaned tool results rendering as raw text during pagination

Sessions load in pages from the bottom up, so a loaded page often contains
a tool_result whose tool_use sits in an older, not-yet-loaded page. That
result wasn't recognized as attached, so it was pushed as a standalone
assistant message and its raw output rendered as unstyled Markdown. It only
"fixed itself" once the user scrolled up far enough to load the page with
the matching tool_use.

Skip results that have a toolId but no matching tool_use in the loaded set —
they attach and render correctly (inside their command row/group) once the
older page loads. Results with no toolId still render as before.
