RMUX 0.2.0 adds Playwright-style SDK

This is more interesting than a tmux clone: RMUX is trying to make terminals programmable infrastructure, not just interactive shells.

• –The tmux-compatible CLI lowers switching costs, but the real differentiation is the SDK layer and the “code is the user” workflow.
• –Stable IDs, snapshots, waits, and text locators map terminal automation to the Playwright mental model, which is a useful abstraction for agents and CI.
• –Native Windows support via ConPTY and no WSL is a real practical edge for teams that need one automation surface across platforms.
• –The project is still in fresh-preview territory, so the promise is bigger than the proven ecosystem; the 90-command compatibility claim will matter only if the rough edges stay manageable.
• –Best fit is agent orchestration, long-lived remote sessions, and terminal-driven test harnesses rather than casual terminal users.
