Adds a
pisession backend for the pi coding agent, following the structure of the existingcodexbackend.Pi stores sessions as JSONL under
~/.pi/agent/sessions/<munged-cwd>/<timestamp>_<uuid>.jsonl. The first line is a header carrying the session id, start time, and cwd; later entries carry messages, model changes, andsession_infodisplay names. The parser is grounded in pi's officialdocs/session-format.mdand verified against a real session store.internal/piparses the store: header id/cwd, label from the latestsession_infoname (an empty name clears it, matching pi's own/resumepicker) with fallback to the first user message, last activity from entry timestamps, preview messages from user/assistant text blocks.internal/sourceregisters the backend as--source=pi, with a--pishorthand and inclusion in--source=all. Resume execspi --session <jsonl-path>.PI_CODING_AGENT_SESSION_DIR(pi's own env var) overrides the sessions directory.Verified live against a real
~/.pi/agent/sessionsstore:list,preview,resumespec, and--source=allinterleaving all render correctly.Known limitations, matching the codex backend's tradeoffs: the parser walks entries linearly, so previews of branched sessions include abandoned branches, and compaction/branch summaries are not shown. Follow-up candidates kept out of this PR: extracting the JSONL-store helpers now duplicated across grok/codex/pi, and generalizing the per-backend shorthand flags in
cmd/ccsession.
