refactor: move brother_node development artifact to dev/test-nodes subdirectory

Development Artifact Cleanup:
✅ BROTHER_NODE REORGANIZATION: Moved development test node to appropriate location
- dev/test-nodes/brother_node/: Moved from root directory for better organization
- Contains development configuration, test logs, and test chain data
- No impact on production systems - purely development/testing artifact

✅ DEVELOPMENT ARTIFACTS IDENTIFIED:
- Chain ID: aitbc-brother-chain (test/development chain)
- Ports: 8010 (P2P) and 8011 (RPC) - different from production
- Environment: .env file with test configuration
- Logs: rpc.log and node.log from development testing session (March 15, 2026)

✅ ROOT DIRECTORY CLEANUP: Removed development clutter from production directory
- brother_node/ moved to dev/test-nodes/brother_node/
- Root directory now contains only production-ready components
- Development artifacts properly organized in dev/ subdirectory

DIRECTORY STRUCTURE IMPROVEMENT:
📁 dev/test-nodes/: Development and testing node configurations
🏗️ Root Directory: Clean production structure with only essential components
🧪 Development Isolation: Test environments separated from production

BENEFITS:
✅ Clean Production Directory: No development artifacts in root
✅ Better Organization: Development nodes grouped in dev/ subdirectory
✅ Clear Separation: Production vs development environments clearly distinguished
✅ Maintainability: Easier to identify and manage development components

RESULT: Successfully moved brother_node development artifact to dev/test-nodes/ subdirectory, cleaning up the root directory while preserving development testing environment for future use.

+/**
+ * @dev Implementation of the ERC-4626 "Tokenized Vault Standard" as defined in
+ * https://eips.ethereum.org/EIPS/eip-4626[ERC-4626].
+ *
+ * This extension allows the minting and burning of "shares" (represented using the ERC-20 inheritance) in exchange for
+ * underlying "assets" through standardized {deposit}, {mint}, {redeem} and {burn} workflows. This contract extends
+ * the ERC-20 standard. Any additional extensions included along it would affect the "shares" token represented by this
+ * contract and not the "assets" token which is an independent contract.
+ *
+ * [CAUTION]
+ * ====
+ * In empty (or nearly empty) ERC-4626 vaults, deposits are at high risk of being stolen through frontrunning
+ * with a "donation" to the vault that inflates the price of a share. This is variously known as a donation or inflation
+ * attack and is essentially a problem of slippage. Vault deployers can protect against this attack by making an initial
+ * deposit of a non-trivial amount of the asset, such that price manipulation becomes infeasible. Withdrawals may
+ * similarly be affected by slippage. Users can protect against this attack as well as unexpected slippage in general by
+ * verifying the amount received is as expected, using a wrapper that performs these checks such as
+ * https://github.com/fei-protocol/ERC4626#erc4626router-and-base[ERC4626Router].
+ *
+ * Since v4.9, this implementation introduces configurable virtual assets and shares to help developers mitigate that risk.
+ * The `_decimalsOffset()` corresponds to an offset in the decimal representation between the underlying asset's decimals
+ * and the vault decimals. This offset also determines the rate of virtual shares to virtual assets in the vault, which
+ * itself determines the initial exchange rate. While not fully preventing the attack, analysis shows that the default
+ * offset (0) makes it non-profitable even if an attacker is able to capture value from multiple user deposits, as a result
+ * of the value being captured by the virtual shares (out of the attacker's donation) matching the attacker's expected gains.
+ * With a larger offset, the attack becomes orders of magnitude more expensive than it is profitable. More details about the
+ * underlying math can be found xref:ROOT:erc4626.adoc#inflation-attack[here].
+ *
+ * The drawback of this approach is that the virtual shares do capture (a very small) part of the value being accrued
+ * to the vault. Also, if the vault experiences losses, the users try to exit the vault, the virtual shares and assets
+ * will cause the first user to exit to experience reduced losses in detriment to the last users that will experience
+ * bigger losses. Developers willing to revert back to the pre-v4.9 behavior just need to override the
+ * `_convertToShares` and `_convertToAssets` functions.
+ *
+ * To learn more, check out our xref:ROOT:erc4626.adoc[ERC-4626 guide].

+/**
+ * @dev Interface of the ERC-20 Permit extension allowing approvals to be made via signatures, as defined in
+ * https://eips.ethereum.org/EIPS/eip-2612[ERC-2612].
+ *
+ * Adds the {permit} method, which can be used to change an account's ERC-20 allowance (see {IERC20-allowance}) by
+ * presenting a message signed by the account. By not relying on {IERC20-approve}, the token holder account doesn't
+ * need to send a transaction, and thus is not required to hold Ether at all.
+ *
+ * ==== Security Considerations
+ *
+ * There are two important considerations concerning the use of `permit`. The first is that a valid permit signature
+ * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be
+ * considered as an intention to spend the allowance in any specific way. The second is that because permits have
+ * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should
+ * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be
+ * generally recommended is:
+ *
+ * ```solidity
+ * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {
+ *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}
+ *     doThing(..., value);
+ * }
+ *
+ * function doThing(..., uint256 value) public {
+ *     token.safeTransferFrom(msg.sender, address(this), value);
+ *     ...
+ * }
+ * ```
+ *
+ * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of
+ * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also
+ * {SafeERC20-safeTransferFrom}).
+ *
+ * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so
+ * contracts should have entry points that don't rely on permit.
