Add octomux to Parallel Agent Runners

[ShreyPaharia]

Adds octomux — a local dashboard for running parallel Claude Code and Cursor agents, each in its own git worktree, with a unified permission inbox, live monitor grid, and in-app diff review. MIT, open source.

Placed alphabetically in Parallel Agent Runners (between nimbalyst and openkanban), matching the existing one-line entry format. Thanks for maintaining the list!

Octomux feels like a strong fit for this list.

The distinction that keeps getting more important in this category is that worktree / parallel-agent dashboards solve operator throughput, while a separate control or evidence layer solves whether the parallel work actually converged into something trustworthy.

Helpful to see the runner surfaces getting mapped cleanly as the space fragments.
