Fix PR review comments: remove code duplication and improve test assertions

[Copilot]

Addresses review feedback on PR #7 regarding code duplication, a typo, and insufficient test validation.

Changes

• Restored scripts/utils.js - Centralizes getMajorVersion utility instead of duplicating across validate-frontmatter.js and functional-tests.js
• Fixed markdown heading typo - o# → # in 001-accessibility-expert-agent/spec.md
• Strengthened test assertions - Validates exactly 12 tools are registered by:
  • Asserting test array length equals 12
  • Counting actual vscode.lm.registerTool calls in extension.js
  • Previously only checked that registration calls existed, not the count

// Before: only checked presence
for (const tool of allTools) {
  assert(content.includes(`vscode.lm.registerTool('${tool}'`));
}

// After: validates exact count
assert.strictEqual(allTools.length, 12);
const registrations = content.match(/vscode\.lm\.registerTool\(/g) || [];
assert.strictEqual(registrations.length, 12);
