465 tests loaded the stock interface off the install without declaring
it, and 25 addon tests assumed the install beside the corpus; each now
opens with `wow_data_or_skip!`. The gates run the workspace tests a
second time with `WOW_DATA=`, so a test that reads the install
undeclared fails at land instead of on a contributor's clone. The skip
log writes each line in one call so parallel tests do not interleave.
Verified: the workspace tests with `WOW_DATA=` in a checkout that has
the addon corpus pass 6972, fail 0, and log 1555 skips; on a fresh
clone of main before this change they failed 465.
