Documentation Update & Demo Template

Summary

Major documentation overhaul to document all features added since v2.4.0, including advanced Handlebars helpers, notebook-specific defaults, mobile support, and new special variables. Added comprehensive demo template with syntax fixes.

Changes

1. Code Quality

• Fixed linting: Standardized string quotes to double quotes across 6 files (19 instances)
• Removed inferrable type annotation in templates.ts

2. Documentation (README.md)

• Added complete documentation for 6 Handlebars helpers (compare, condition, math, case, repeat, datetime)
• Documented template_todo_alarm special variable (previously undocumented)
• Expanded Default Templates section with notebook-specific defaults guide
• Added Mobile Support section with platform-specific guidance
• Updated Table of Contents with new sections

3. Demo Template (DEMO_TEMPLATE.md)

• Created comprehensive feature demonstration template showcasing all plugin capabilities
• Includes 8 custom variables, all helpers, special variables, and real-world examples
• Fixed YAML syntax issues (proper quoting for special characters)
• Fixed datetime formats (set_time without seconds, template_todo_alarm as YYYY-MM-DD HH:mm)
• Fixed condition helper usage (replaced incorrect NOT with Handlebars {{#unless}})
• Fixed template_tags quoting to prevent HTML entity encoding

Impact

• All features since v2.4.0 now documented
• Demo template for testing and learning
• Improved user onboarding with clear examples and guidance
