Related GitHub Issue

Closes: #8597

Description

This PR adds support for the .al (AL Language) file extension used in Microsoft Dynamics 365 Business Central development. Since there is no dedicated WASM parser available for AL Language, this implementation uses fallback chunking similar to other languages like VB.NET, Scala, and Swift.

Test Procedure

   pnpm test src/services/code-index/processors/__tests__/parser.vb.spec.ts

Manual Testing

1. Create a test AL file (e.g., test.al) with sample AL Language code

table 50100 "Customer Extension"
{
    fields
    {
        field(1; "No."; Code[20]) { }
        field(2; "Name"; Text[100]) { }
    }
}

2. Open the file in the codebase and verify it's properly indexed
3. Confirm that the code parser processes the file using fallback chunking without errors
