Matryoshka v1.0.0

Added

• Matryoshkas of up to nine figures: notes, photos and voices inside, the present in the smallest, solid one.
• Locks: time (with a notification), riddle and someone's word (real encryption), place (within 50–300 m), gesture (cover, shake, turn over).
• The .matr file: a chain of keys, AES-GCM, PBKDF2 for answers; sent through any messenger.
• Shared matryoshkas passed round in a set order, everyone painting one figure; the last one seals it.
• Replies from the recipient (words and voice) sent back as a file.
• Shelf of given and received matryoshkas, workshop with drafts, onboarding, limewood and lacquer themes, English and Russian.
