docs(the-workshop): fix workshop scaffold, bench location, and component list

Address the remaining doc/skill review findings:
- workshop-create: 'gh repo create --clone' clones into the CWD, which
  nests the new repo when run from inside a checkout. Add an explicit
  clone-parent selection + 'rev-parse --is-inside-work-tree' guard, and
  run the create from that parent.
- workshop-create: desks/ and bench/ were scaffolded empty, so Git drops
  them and a later clone loses the scaffold. Scaffold .gitkeep in each
  and commit the placeholders.
- bench-read: make <workshop>/bench/ the primary shared location (the
  directory workshop-create actually establishes) with desk-local
  artifacts as a secondary source, instead of treating the repo root as
  the bench.
- the-workshop README: add the Workshop Create skill to the component
  table so all six packaged components are documented.

 ## Where to look
 
-The bench is the workshop directory itself and its subdirectories.
-Common patterns:
+The primary shared location is the `bench/` directory at the
+workshop root — the designated cross-desk workspace. Desk-local
+artifacts under `desks/<desk-name>/` are a secondary source: read
+them when you need a specific desk's own work, but shared artifacts
+belong in `bench/`.
