sw-view

Opens the viewer on this project's vault. One command; the user picks nothing. Do not read vault files or generate HTML yourself.

Run from the project root:

node docs/.sw/sw.mjs serve --open

It starts a small local server for this project (or reuses the one already running), prints its address, and opens it in the default browser. The page reads the files as they are: after the vault changes, Refresh in the page shows the new state. The server answers only on this machine and stops by itself after two hours without use.

Tell the user the address it printed and that Refresh re-reads the files. Nothing else.

If it fails

Problem	Do
docs/.sw/sw.mjs or docs/viewer.html missing	say so; offer to run sw-init, which installs them
"could not start the viewer server"	node docs/.sw/sw.mjs snapshot, then open docs/viewer.html as a file (open, xdg-open or start). Tell the user this view is frozen at the moment of the snapshot; running sw-view again refreshes it
No browser on this machine (remote session)	give the user the snapshot path instead: docs/viewer.html opens on any machine that has the docs/ folder

If the user asks a question the viewer answers (counts, what is ready, what blocks a task), answer it with node docs/.sw/sw.mjs status|ready|check <ID> instead of opening the browser.
