A one-fix patch release: an unterminated ${ placeholder in a seed fixture is now rejected instead of being seeded as literal text.

Highlights

01
A placeholder typo fails the test, not the data
A seed fixture containing "note": "${orderId" uses a ${ with no closing brace. It used to pass straight through the rewriter and seed the literal string ${orderId. The typo became test data silently: the assertion that depended on it failed somewhere unrelated, or passed for the wrong reason. The rewriter now raises PlaceholderException naming the fixture, the JSON path and the offending text, and points at the $${...} escape for a genuinely literal ${...}. Escaped placeholders and ordinary $ text behave exactly as before.

The seed placeholder rewriter rejects an unterminated ${ with a PlaceholderException naming the source, JSON path and offending text, instead of emitting it as a literal string. Found while porting the same engine to a sibling project, and fixed identically in both.
