/// - Mint must exist (mint_decompressed = true) - unless idempotent is set
/// - is_compressible() must return true (rent expired)
/// - Cannot be combined with DecompressMint in same instruction
///
/// ## Note
/// CompressAndCloseMint is **permissionless** - anyone can compress and close a Mint
/// provided is_compressible() returns true. All lamports are returned to rent_sponsor.
