NoChangeError message has broken ToolName interpolation and typo

[ShehabSherif0]

Bug

In src/extension/tools/node/editFileToolUtils.tsx (line 671), the NoChangeError message uses single quotes for a string containing ${ToolName.ReadFile}:

throw new NoChangeError(
    'Original and edited file match exactly. Failed to apply edit. Use the ${ToolName.ReadFile} tool to re-read the file and and determine the correct edit.',
    filePath
);

Two issues on the same line

1. Broken template interpolation: Single-quoted strings do not support ${...} interpolation in JavaScript/TypeScript. The model literally receives the text ${ToolName.ReadFile} instead of read_file. Additionally, ToolName is not imported in this file, so even changing to backticks alone would cause a ReferenceError.

2. Doubled word typo: "re-read the file and and determine" has a duplicate "and".

What the model sees today

String replacement failed: Original and edited file match exactly. Failed to apply edit. Use the ${ToolName.ReadFile} tool to re-read the file and and determine the correct edit.

What it should see

String replacement failed: Original and edited file match exactly. Failed to apply edit. Use the read_file tool to re-read the file and determine the correct edit.

Impact

This error triggers when replace_string_in_file produces no actual change (e.g., the model's edit matched via fuzzy/whitespace matching but the replacement yielded identical content). The garbled tool name prevents the model from following the recovery instruction to re-read the file, degrading agent mode's ability to self-correct on failed edits.

Proof

const ToolName = { ReadFile: 'read_file' };
const bugged = 'Use the ${ToolName.ReadFile} tool';
const fixed  = `Use the ${ToolName.ReadFile} tool`;
console.log('BUGGED:', bugged); // "Use the ${ToolName.ReadFile} tool"
console.log('FIXED: ', fixed);  // "Use the read_file tool"

Fix

1. Add import { ToolName } from '../common/toolNames';
2. Change single quotes to backticks
3. Fix and and to and

Every other usage of ToolName.* in the codebase uses backtick template literals correctly. This is the only instance using single quotes.
