fix(session): log --last 0 means no backlog

debug.log handed `last` to the timeline query, where 0 means every
entry, so `log --follow --last 0` streamed the whole ring of up to 8192
entries before the new ones, where an agent reads it as tail -n 0 -f:
nothing old, only what comes next. 0 now means no backlog, followed or
not, and the guide says that --follow starts with the last 50.
