Velox VX Language

This extension adds language support for .vx and .VX files:

• Syntax highlighting
• LSP-powered autocomplete (project symbols + snippets)
• LSP hover, go-to-definition, references, rename, signature help
• Semantic tokens and workspace symbol search
• Quick fixes for common diagnostics (.js import fixup, missing render scaffold, duplicate-name suggestions)
• Document symbols (components, params, state, @fast)
• Alias-aware import rename/definition behavior across files
• Server-side structural diagnostics (duplicates, missing render, import resolution)
• On-save/on-open diagnostics via velox check
• Explorer file decoration badge (VX) on Velox files
