Keep browsing, streaming, editing, downloads, and live file observation inside the selected workspace runtime. Helper processes own cancellation and teardown so remote workspaces never fall back to host paths.
Keep terminal state in Paseo while allocating PTYs and running terminal commands in the selected workspace runtime. Runtime exit and cleanup remain authoritative across worker and wrapper failures.
Establish the pipe-mode vertical slice before migrating terminals, files, Git, and providers. Runtime selection is immutable per workspace, and external runtimes remain unavailable to path-based daemon surfaces until those capabilities move behind the boundary.
