Solidity Compiler Error 9467: Inline Assembly Variables With 'slot' Suffix Causing False Identifier Not Found Errors

## Description

The Solidity compiler is incorrectly interpreting variable names in inline assembly that end with "_slot" (e.g., "from_slot") as attempts to access storage variables rather than as locally declared assembly variables. This causes compilation `error 9467: "Identifier not found. Use '.slot' and '.offset' to access storage or transient storage variables."`

When using variable names like "from_slot" or "to_slot" in inline assembly, the compiler mistakenly interprets these as attempts to access storage slot properties. However, when the same variables are renamed to "slot_from" or "slot_to" (moving the word "slot" to the beginning), the code compiles successfully. This suggests the compiler is incorrectly parsing variable names that end with "_slot".

## Environment

- Compiler version:0.8.28

## Steps to Reproduce

```solidity
// SPDX-License-Identifier: MIT
pragma solidity 0.8.28;
contract test{
function transfer(address _to, uint256 _value)public{
assembly{
let ptr:=mload(0x40)
mstore(ptr,caller())
mstore(add(ptr,0x20),1)
let from_slot:=keccak256(ptr,0x40)
let from_Balance:=sload(from_slot)
}
}
```

-->

Start by compiling the Solidity reproduction with compiler version 0.8.28, then compare the failing `from_slot` and `to_slot` names with the working `slot_from` and `slot_to` variants. Trace the compiler's inline-assembly identifier handling and add coverage showing that locally declared names ending in `_slot` are accepted without the storage-variable error.
