fix(remote): leave the remote-history PATH bootstrap out of this PR

Merge-time fix for #645: the PATH bootstrap for remote history reads
(src/remote-pane-history.ts, src/remote-hosts.ts and its test) is a
separate fix from the scroll work. On its own it does not reach a host
whose tmux lives only under /opt/homebrew/bin, because the link
precheck, the launch, the alive probe and discovery still run a bare
tmux through the same non-interactive ssh shell. It belongs in a
follow-up PR that routes every remote tmux call through one wrapper.
These files are restored to the PR's merge base; every scroll change
stays.
