Subject: [PATCH] fix: update account ID size from 64-bit to 120-bit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Description:
Corrected a discrepancy in the documentation: the account ID size is specified as 64-bit, although the current specification uses 120-bit.

## Problem:

`docs/design/index.md (line 51)` specifies a 64-bit Account ID, which contradicts:
- docs/builder/quick-start/accounts.md:52 (120-bit)
- docs/builder/quick-start/setup/cli-basics.md:95 (120-bit)
all current v0.12 documentation

## Changes:

Replaced “64-bit” with “120-bit” in the Account ID description.

 Accounts are programmable entities that hold assets and execute code:
 
-- **ID** – Unique 64-bit identifier derived from initial code and storage
+- **ID** – Unique 120-bit identifier derived from initial code and storage
 - **Code** – Immutable smart contract logic defining the account's interface
 - **Storage** – Key-value store with up to 256 slots for persistent data
 - **Vault** – Container holding fungible and non-fungible assets
