Document IDE0410: Use labeled jump statement

[Copilot]

Adds missing documentation for IDE0410, which flags code that can be simplified using C# 15's labeled break/continue statements.

Changes

• New ide0410.md: Full rule reference covering:
  • Three detected patterns: goto → break <label>, goto → continue <label>, and boolean flag pattern → labeled jump
  • csharp_style_prefer_labeled_jump_statements option (default: true, C# 15+)
  • Code examples for each pattern and suppression instructions
• index.md: Added IDE0410 row between IDE0391 and IDE1005
• language-rules.md: Added IDE0410 to the Code-block preferences section
• toc.yml: Added IDE0410 navigation entry

Example

The rule converts workarounds like this:

// Before: goto pattern
for (int x = 0; x < 10; x++)
{
    for (int y = 0; y < 10; y++)
    {
        if (x * y > 20)
            goto found;
    }
}
found:
Console.WriteLine("Done");

// After: labeled break (C# 15+)
found: for (int x = 0; x < 10; x++)
{
    for (int y = 0; y < 10; y++)
    {
        if (x * y > 20)
            break found;
    }
}
Console.WriteLine("Done");

It also detects boolean flag patterns used to propagate breaks across loop levels, replacing them with a single break <label> or continue <label>.

Pull request overview

This PR adds the missing documentation for code style rule IDE0410, which encourages using C# 15+ labeled break/continue statements instead of goto-based or flag-based nested-loop control flow, and wires the new page into the existing style-rules navigation and indexes.

Changes:

• Added a new rule reference page: ide0410.md (overview, option details, examples, and suppression guidance).
• Updated the style-rules overview index and the language rules list to include IDE0410.
• Added IDE0410 to the tools-diagnostics TOC so it appears in navigation.
