mode-functions writes without a parse check when a mode wrapper survives
holding api entries, since that intermediate state is unparseable until
move-api-blocks runs later in the same pass. Brace balance is the invariant
a bad splice offset would break, so check that instead; nothing downstream
could tell a corrupted wrapper from an untouched one.
Also records that Task 5's example-app migration ran against an already-
migrated target and so did not prove end-to-end behaviour.

- rebuild editors/vscode bundles, stale since the parser escape fix
- attach the caught ParseError as `cause` in both migration validators
- drop two unused test bindings flagged by eslint
