The tmux teammate-mode investigation is resolved (works on 2.1.148; the
'broken regression' was a teammateMode: in-process config issue). Per the
file's own cleanup note, delete it now that the test passes.
Update the two references:
- decisions/questions-process.md: replace the stale 'partially broken'
pointer with the resolved status.
- whats-next/SKILL.md: the 'custom subagent_types lose SendMessage' caveat is
fixed (all agents now carry SendMessage + Task tools), so reword and drop
the dead team-test.md link.
