Addresses CodeRabbit review on #1006.
The "more:" hint echoed only `--page`, `--size`, and `--reverse`, so copying
it off a scoped invocation dropped `-w`, `-p`, and `--ids` — landing on a
different workspace or an unfiltered transcript. Hint construction moves into
`_next_page_command` in the command module, which knows the invocation; the
renderer now just prints the string it's handed and no longer needs to know
CLI flag syntax. Only flags passed explicitly are echoed, since anything from
the environment or config resolves the same way on the next run.
Also rejects non-positive `--last` on `honcho message list`, which slice
semantics turned into a silently empty result. `session view` already errored
on it; the two now agree.
