feat(dw): 🎸 split provisioning from dev server for orchestrator setup/run/teardown

Conductor and Superset distinguish setup (one-shot provisioning on
workspace creation), run (restartable dev server bound to the Run
button's pane), and teardown (cleanup on deletion). The single 'bun dw'
entrypoint conflated all three. Splits cmdDefault into cmdSetup
(provision only, returns the registry entry) and cmdRun (load entry,
kill ports, startDev inline). Adds startDev opts.allowTmux so cmdRun
forces inline regardless of TTY — the Run pane owns the process. Direct
CLI 'bun dw' still works byte-for-byte via the default.ts shim. Replaces
.superset/setup.sh and .conductor/config.json with the three-field {
setup, run, teardown } shape pointing at the new subcommands. Adds
scripts/dw/README.md as the agent-facing guide.
