sl0p: --purpose flag and tab-level purpose

2026-08-12T16:44:24Z

Completes the two pieces deferred from the first workspace-hints pass. `zellij run --purpose X` / `zellij action new-pane --purpose X` tag a pane at spawn time, which is what an agent wants for panes it creates itself; the OSC wrapper still works for programs that declare their own role. Not supported with --in-place, which replaces another pane rather than being a pane of its own: clap rejects the combination rather than accepting a flag that would do nothing. `tab name="work" purpose="agent-work"` gives a whole tab a role, reported by `list-tabs --json`. It rides the tab's ROOT layout node, reusing the pane field because a tab's root is the tab container and never itself a pane -- asserted by a test for the tightest case (a tab holding exactly one pane), since a leak there would silently mislabel a pane. The interesting part is why the flag first shipped broken. There are TWO protobuf boundaries -- the plugin API and the client->server IPC contract -- and a CLI flag must cross the second one. Defaulting the field in the conversion (what "no protoc" usually forces) compiles cleanly and then silently drops the value in transit, so --purpose parsed, printed a pane id, and did nothing. Fixed by adding the field to both contracts by hand, in the .proto AND the committed generated prost, kept in lockstep so a future regeneration reproduces it: protoc is only needed to regenerate, not to build. Both boundaries now have a round-trip test, and the IPC one was confirmed to fail when the wire read is removed. Sanitising moved to Grid::set_authoritative_purpose, the single choke point every out-of-band source passes through, after the CLI path was observed delivering `bad purpose; rm -rf /` intact into list-panes --json.

feat(cli): add --pane-id option to dump-screen action (#4598)

2026-03-09T13:55:14Z

* feat(cli): add --pane-id option to dump-screen action Adds the ability to dump a specific terminal pane's content by passing `--pane-id ` to the `dump-screen` CLI action. When omitted, the existing behavior of dumping the focused pane is preserved. This enables coding agents running inside Zellij to inspect the content of other panes programmatically, without needing complex workarounds. Prior art: https://github.com/theslyprofessor/zellij-pane-tracker, whose design complexity is due to current limitations that this PR addresses. * address review * improve man page entry
