Codama visitor for deduplicating instruction accounts from Anchor IDL

import { instructionAccountNodeFromAnchorV01 } from "@codama/nodes-from-anchor";
//#region src/instruction-account-nodes-from-anchor-v01.ts
/**
* Recursively flattens nested instruction account structures from Anchor IDL v0.1.0 format.
*
* This function handles the nested account structures (account groups) that appear in
* Anchor IDLs and flattens them into a single array of instruction account nodes.
* Parent-child relationships are preserved through naming conventions.
*
* @param allAccounts - All account nodes available in the program
* @param instructionArguments - Arguments for the instruction
* @param idl - The instruction account items from the Anchor IDL, potentially nested
* @param parent - The parent account name prefix for nested accounts
* @returns Flattened array of instruction account nodes
*
* @example
* ```typescript
* // Given nested accounts:
* const nested = [
*   {
*     name: "mintAccounts",
*     accounts: [
*       { name: "mint", ... },
*       { name: "metadata", ... }
*     ]
*   }
* ];
*
* // Returns flattened:
* // [
* //   { name: "mintAccounts_mint", ... },
* //   { name: "mintAccounts_metadata", ... }
* // ]
* ```
*
* @remarks
* - Account names are joined with underscores when nested
* - PDA seed paths are updated to include the parent prefix
* - Recursively processes nested account groups
