Eric Huss	d7892f5601	Add optional field for preprocessors ... This adds the `optional` field to the preprocessor configuration to mirror the same option for the `output` table. Missing preprocessors are now an error unless the `optional` field is set. This should help with inadvertently building a book when a missing preprocessor that you expect to be installed.	2025-08-16 13:39:54 -07:00
