Enhancement: Session templates for quick setup and standardization

[vultuk]

Description

Create a template system that allows users to define reusable session configurations for quick setup and consistent environments.

Problem Statement

• Repetitive manual setup for similar sessions
• Inconsistent configurations across sessions
• Time wasted on initial session setup
• No way to share common configurations

Template Actions

• Create from Session: Save current session as template
• Edit Template: Modify existing templates
• Share Template: Export/import via JSON
• Fork Template: Create variation of existing
• Delete Template: Remove unused templates

Smart Features

Variable Substitution

// Template variables
${PROJECT_NAME}     // Prompt user for value
${GIT_BRANCH}       // Auto-detect from git
${TIMESTAMP}        // Current timestamp
${RANDOM_PORT}      // Random available port
${USER_HOME}        // User home directory
${LAST_DIRECTORY}   // Previous working directory

Conditional Logic

initialization:
  - command: "docker-compose up"
    condition: "exists:docker-compose.yml"
  - command: "npm start"
    condition: "exists:package.json && !exists:docker-compose.yml"
  - command: "python app.py"
    condition: "exists:requirements.txt"

Template Inheritance

extends: "base-node-template"
overrides:
  environment:
    NODE_ENV: "production"
  initialization:
    - command: "npm run build"
    - command: "npm run start:prod"
