BRO-024: reduce the context URI to //WT/dir/ ($PWD); prompt-like address bar //WT/dir/: verb args; cd before verbs

Now
DONE

The fat context URI (authority+path+?rev+#hash all mutable slots) is not working well; ruled 2026-07-12 to reduce context to worktree+path only, exactly $PWD for the verbs. The pager address bar becomes a shell-like invite: context left of : , verb invocation right of it. Verbs execute with the process actually cd'ed into the context dir so nothing is mistaken; the revision axis leaves context and goes explicit into spells and links. Rewrites the context part of Nav (already flagged stale, BRO-023, BE-030).
