[Feature]: Daily note calendar integration with template variables

[CodeWithInferno]

Problem

When creating daily notes, users have to manually check their calendar and copy events. The daily note doesn't automatically include the day's schedule.

Solution

Add calendar template variables for daily notes.

Template Variables

• {{calendar:today}} - List of today's events
• {{calendar:tomorrow}} - Tomorrow's events
• {{calendar:week}} - This week's events
• {{calendar:agenda}} - Next N upcoming events
• {{calendar:date:YYYY-MM-DD}} - Specific date's events

Example Daily Note Template

# {{date:dddd, MMMM D, YYYY}}

## Today's Schedule
{{calendar:today}}

## Tasks Due Today
{{tasks:due_today}}

## Notes

## End of Day Review

Rendered Output

## Today's Schedule
- 09:00 - 10:00: Team Standup
- 14:00 - 15:00: 1:1 with Manager
- 16:00 - 17:00: Sprint Planning

Implementation Tasks

• Add calendar variable parser to daily note template system
• Implement {{calendar:today}} variable
• Implement {{calendar:tomorrow}} variable
• Implement {{calendar:week}} variable
• Implement {{calendar:agenda}} with configurable count
• Add event formatting options (time format, include location, etc.)
• Document new template variables
