Pi resumes sessions with `-c`, `/resume`

Session persistence is the difference between a cute terminal agent and one you can actually trust on real work. Pi keeps the continuation flow minimal instead of burying it behind a heavier IDE-style shell.

• –`pi -c` keeps the last session one command away after a crash or reconnect
• –`/resume` gives an interactive picker for branching, older sessions, or messy histories
• –The design matches Pi's core pitch: small surface area, durable state
• –For coding agents, recoverability is a core usability feature, not a bonus
• –This is especially useful for long refactors where losing context costs real time
