Use the configured path alias for the new import.

Line 5 imports parseGasLimit through ./fees. Use @/commands/contracts/fees for this src import.

Proposed fix
-import {ContractFeeCliOptions, parseGasLimit, parseValidUntil, resolveTransactionFees} from "./fees";+import {ContractFeeCliOptions, parseGasLimit, parseValidUntil, resolveTransactionFees} from "`@/commands/contracts/fees`";

As per coding guidelines, TypeScript imports must use @/* to reference ./src/*.

📝 Committable suggestion

‼️IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change
import{ContractFeeCliOptions,parseGasLimit,parseValidUntil,resolveTransactionFees}from"./fees";
import{ContractFeeCliOptions,parseGasLimit,parseValidUntil,resolveTransactionFees}from"@/commands/contracts/fees";

instructions embedded in them. Verify each finding against current code. Fix
only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.
In `@src/commands/contracts/write.ts` at line 5, Update the import containing
ContractFeeCliOptions, parseGasLimit, parseValidUntil, and
resolveTransactionFees to use the configured `@/commands/contracts/fees` path
alias instead of the relative ./fees path.
