Document this release's two connect changes that landed via #19 and #20:
- CHANGELOG [Unreleased]: Added entry for /new vs /clear using each
channel's real session op (opencode DELETE /session); Fixed entry for
the opencode 30s client-timeout that aborted long agent turns.
- robot-quickstart.md: a 会话指令 section explaining /new (open fresh,
keep old) vs /clear (real per-channel wipe; opencode deletes the
server session).
Docs only; no code change.
