Adds support for the Vento template language to the Zed code editor.

• Syntax highlighting for Vento template files (.vto, .vento)
• YAML front matter support with proper language injection
• HTML injection for template content
• JavaScript injection for code blocks
• Complete support for all Vento keywords and constructs

All Vento keywords are properly parsed and highlighted:

• {{ if }} / {{ /if }} - Conditional blocks
• {{ else if }} - Else-if branches
• {{ else }} - Else branches
• {{ for }} / {{ /for }} - Loop blocks (with optional await)

• {{ set }} / {{ /set }} - Variable assignment (tag and block forms)
• {{ echo }} - Output expressions

• {{ layout }} / {{ /layout }} - Layout blocks
• {{ slot }} / {{ /slot }} - Slot definitions
• {{ default }} / {{ /default }} - Default content blocks
• {{ include }} - Include other templates
• {{ fragment }} / {{ /fragment }} - Fragment blocks (plugin)

• {{ function }} / {{ /function }} - Function definitions (with optional export, including export async)
• {{ import }} - Import from other templates
• {{ export }} / {{ /export }} - Export variables (tag and block forms)

• {{> }} - JavaScript execution tag
• {{# #}} - Comment tag

This extension supports YAML front matter at the beginning of Vento templates:

---
title: My Page
date: 2024-01-01
tags:
  - vento
  - template
---

<h1>{{ title }}</h1>

The YAML content within the front matter delimiters (---) will be properly highlighted and treated as YAML.
