alonso.torres 97abc1ea18 ✨ Record a golden master of the component code
Before refactoring the component sync code, record the exact files the
component tests produce, so a refactor that changes any of them fails.

The JVM test common-tests.logic.golden-master-test runs every variant of
the composable cases the pure runner runs and every benchmark world. It
records the file after each user, undo and redo step (the runner's new
:observe option), the final files with the signatures of the undo/redo
round trip failures, and each world's file after its timed work. The
frontend interpreter records the store's files of every variant of its
cases and of the completion contract the same way.

app.common.test-helpers.golden-master writes a state as the normalized
files in sorted "path value" lines: ids become test labels, or numbers
in tree order when unlabelled; grid cells are named after their shape
and position; timestamps are left out. So a state is the same in every
run whatever ids it draws. Only a digest per state is committed; the
full lines go to tmp/golden-master/ and tmp/golden-master-frontend/
(recorded/, and actual/ for a state that differs), so diff -r shows a
change. PENPOT_GOLDEN_MASTER=record records them again.

Both sides repeat exactly across runs. Dropping :opacity from the
attributes sync copies fails the case C variants that edit it.

The interpreter's fixture also turns cts/wasm-enabled? off for each
composable test and restores it after, as it already restores the
store. A test that starts the WASM renderer left the flag on, so in a
full frontend run the cases ran on WASM shape proxies, which leave out
the attributes that are nil or false, and the frontend golden master
differed from a run of the cases alone (:flip-x and :flip-y).
