* fix(preflight): follow every /Next action and bound colour and intent work Action chains followed an indirect /Next only when it named an array, and skipped references inside a /Next array, so a forbidden action one indirect hop behind an allowed one survived both verification and conversion; an untyped dictionary with /P and /K was exempt from action checks whatever its /S. Both are now followed and checked, and arrays are borrowed instead of deep-copied per chain. Conversion treats a /Subtype /Widget without /Type as an annotation, and takes forbidden annotations off their pages in one pass. Device-colour inspection decoded each content stream with the 1 GiB per-stream default and no total; it now shares one 1 GiB DecodeBudget and reports unread content instead of treating it as clean. Type 3 CharProcs shared by many fonts are read once, and declared() reads each output intent once (at most 8). * address review: no sRGB intent when colour couldn't all be read; count array reads in action chains; declare every output intent * address review: cut only an over-long identifier; test with a filter that can't be read * review: leave untyped structure elements out of the forbidden-action check * merge main, keep both * address review: a wide direct /Next array is refused before it is queued; queued references are resolved through aliases
