Create a new session DB row when starting fresh from the CLI, reset the agent DB flush cursor and todo state, and update session timing/session ID bookkeeping so follow-up logging stays correct. Also update slash-command descriptions and add regression tests for /new, /reset, and /clear. Supersedes PR #899. Closes #641.
