feat(api): full PHP API coverage for products flagged fullApi (Gravity Forms) (#5)

Adds a per-product `fullApi` flag (repos-config.json) that documents every
non-internal class and non-underscore function, bypassing the @api/@see
reference filter. Enables it for Gravity Forms, whose canonical classes
(GFAPI, GFCommon, GFFormsModel, ...) are not @api-tagged upstream.

gravityforms: 13 -> 627 symbols (353 classes, 274 functions); GFAPI now
documented (57 methods).
