Merge main into the Phase 17 refactor

`main` changed the four files this branch split into packages, so all four
came back as modify/delete conflicts. Each change is ported to the module
that now holds the code, unchanged in behavior:

- `delete_action` moves to `routers/adventures/actions.py`. It reaches the
  turn lock as `turns.acquire_turn_lock` and `turns._active_turns`, which is
  the rule this branch set: the package root no longer re-exports the names a
  test rebinds.
- `EMIT_RULE` moves to `worldstate/parse.py`, and `_describe_stat` and
  `render_reference` to `worldstate/render.py`.
- The chip-wrap rules move to `styles/schema-editor.css`, and
  `StateChangeChips` to `pages/Play/reports.jsx`. `index.css` keeps this
  branch's import list.

`test_delete_state.py` needed four edits to run here. It drops the eight-line
database prologue, because `conftest.py` does that once now. It imports the
shared `ScriptedProvider` from `fakes.py` instead of carrying a copy. It
patches `adventures.turns.OpenAICompatibleProvider` and reaches the lock the
same way. And it no longer passes `index=0` when it builds the start action,
because migration 71 drops that column.

564 tests pass. `npm run lint` and `npm run build` are clean, and the CSS
bundle is 56.71 kB, which is the pre-merge size plus main's new rules.
