feat: wave-3 image + document surfaces — segmentation, colorize, face restore, ocr (ADR-0023)

- imagegen.Segmenter/SegmentationProvider: prompted mask via POST /upstream/<id>/v1/segment (file, prompt[, threshold], output=mask); white = prompted region, EditRequest.Mask polarity. - imagegen.Colorizer/ColorizeProvider: POST /upstream/<id>/v1/colorize. - imagegen.FaceRestorer/FaceRestoreProvider: POST /upstream/<id>/v1/restore_faces (upscale 1|2). - New ocr leaf package (Request/Page/Result, Recognize) + llamaswap OCRModel: POST /upstream/<id>/v1/ocr (file[, langs, max_pages]), tolerant per-page decode (join lines when page text absent), Raw escape hatch. - httptest contract tests per surface; ADR-0023; ADR index backfilled (0020-0022 rows were missing).
