Add a yaml schema file for the gitstream.cm file validation and error free IDE editing

[dorongutman]

Is your feature request related to a problem? Please describe.
I'm always frustrated when my IDE shows error on my gitstream.cm file, for example in the following line:

- {{ (pr.comments | filter(attr='content', term='/bypass_e2e') | filter(attr='commenter', list=['userA']) | some )}}

Describe the solution you'd like
I would like to have a yaml schema file I could reference in my gitstream.cm file so the IDE will show proper validation and maybe even auto complete of possible values.

✅ YAML Schema for gitStream .cm files - Complete!

I've successfully created a comprehensive YAML schema solution for gitStream .cm file validation and IDE support.

Todo List:

• Research existing .cm files and gitStream structure
• Analyze gitStream context variables and filter functions
• Create JSON Schema file for YAML validation
• Test schema against existing .cm files
• Document IDE integration instructions
• Commit changes and create PR

🚀 What Was Delivered

1. JSON Schema File (gitstream-schema.json)

• Complete validation for .cm file structure (manifest, automations, config)
• Support for all context variables (branch, files, pr, repo, source, env)
• Validation for 20+ automation actions with proper arguments
• Jinja2 expression validation and type checking
• Custom expressions support

2. IDE Integration Documentation (docs/ide-integration.md)

• Setup instructions for VS Code, JetBrains IDEs, Neovim, Sublime Text
• Multiple configuration methods (settings vs in-file declarations)
• Troubleshooting guide and contribution guidelines
• Feature overview (validation, autocomplete, error detection)

3. Template Updates

• Added schema reference to main gitstream.cm template for immediate IDE support
• Users will get validation/autocomplete out of the box

🎯 Benefits for Users

• 🔍 Real-time validation: Catch errors before committing
• 💡 Intelligent autocomplete: Context-aware suggestions for actions, variables, and filter functions
• 📚 Inline documentation: Hover help for all gitStream features
• ⚡ Faster development: Reduced trial-and-error when writing automation rules

📋 Example Usage

Just add this line to your .cm files:

# yaml-language-server: $schema=https://raw.githubusercontent.com/linear-b/gitstream/main/gitstream-schema.json

Or configure your IDE once to apply the schema to all .cm files automatically.
