Function in registry: Schedule Trigger node for periodic/workflow execution

[Fanna1119]

Function in registry for Schedule Trigger node

Implement a Schedule Trigger node to run workflows at fixed intervals and times, similar to the Cron utility available in Unix-like systems.

Key Features

• Multiple Trigger Rules:
  • Allow users to add multiple rules for when the node should trigger, supporting different schedules in a single node configuration.
• Trigger Interval Selection:
  • Users should be able to select the trigger interval category:
    • Seconds (e.g., every 30 seconds)
    • Minutes (e.g., every 5 minutes)
    • Hours (e.g., every 6 hours at 30 minutes past the hour)
    • Days (e.g., every 2 days at 9:15am)
    • Weeks (e.g., every 2 weeks on Monday at 3:30pm)
    • Months (e.g., every 3 months on the 28th at 9:00am)
    • Custom Cron Expression
• Parameterisation per Interval:
  • Each interval type should display only the parameters relevant to that schedule. Examples include:
    • Seconds Between Triggers, Minutes Between Triggers, etc.
    • For hourly schedules: select minute of the hour.
    • For daily/weekly/monthly: specify hour(s), minute(s), days of week/month.
    • Custom Cron: accept cron expressions entered manually (crontab guru reference).

Example Parameters

• Seconds Between Triggers
• Minutes Between Triggers
• Hours Between Triggers
• Trigger at Minute (0-59)
• Trigger at Hour (for days/weeks/months)
• Trigger at Day of Month (for months)
• Trigger on Weekdays (for weeks)
• Custom Cron Expression

Goal:
Add a configurable Schedule Trigger node to the function registry to enable automating workflow starts at arbitrary intervals.
