Add rounds and numeric duration/distance to HIIT workouts in blockTemplates.ts

[Copilot]

This PR adds rounds functionality to HIIT workouts and updates the type system to support numeric duration/distance values as requested. HIIT workouts can now specify the number of rounds in addition to duration or distance, providing better clarity for interval-based exercises.

Changes Made

Type System Updates:

• Updated CardioWorkout interface in types.ts to support:
  • duration?: number (seconds for HIIT, minutes for LISS)
  • distance?: number (meters for HIIT, kilometers for LISS)
  • rounds?: number field for interval tracking

Training Templates Updated:
Updated all HIIT workout definitions in blockTemplates.ts to use numeric values:

• Reset-20: Now uses duration: 20 (seconds) and duration: 15 (seconds) with rounds
• Hill Sprints: Uses rounds only (3, 5, 7 rounds)
• GC 9: Uses distance: 100 (meters) with 10 rounds
• 600m Resets: Uses distance: 600 (meters) with 6 rounds
• Tempo Run: Uses distance: 5000 (meters for continuous runs)

UI Enhancement:

• Updated CardioWorkouts.svelte to display duration/distance with proper units
• HIIT workouts show seconds/meters, LISS workouts show minutes/kilometers
• Rounds appear below duration/distance when present
• Preserved existing LISS timer functionality

Examples

Before:

{ type: "hiit", activity: "Reset-20", duration: "20 sec" }
{ type: "hiit", activity: "Hill Sprints", duration: "3 sprints" }

After:

{ type: "hiit", activity: "Reset-20", duration: 20, rounds: 5 }
{ type: "hiit", activity: "GC 9", distance: 100, rounds: 10 }
{ type: "hiit", activity: "Hill Sprints", rounds: 7 }

The UI now clearly shows duration/distance with appropriate units and rounds information for better workout guidance.

Makes progress on #42.

@copilot can you update the types for hiit workouts to allow for either "duration" or "distance" and update src/blockTemplates.ts accordingly? "duration" or "distance" should be numbers not strings. for hiit workouts "duration" is in seconds and "distance" is in meters (for liss workouts i guess it would be minutes and kilometers respectively)

I've updated the types and blockTemplates as requested! The changes include:

Type System:

• CardioWorkout now supports duration?: number and distance?: number
• For HIIT: duration in seconds, distance in meters
• For LISS: duration in minutes, distance in kilometers

All HIIT workouts updated:

• Reset-20: duration: 20 (seconds) with rounds
• GC 9: distance: 100 (meters) with rounds
• Hill Sprints: rounds only
• Tempo Run: distance: 5000 (meters)
• 600m Resets: distance: 600 (meters) with rounds

The UI now displays proper units (seconds/meters for HIIT, minutes/km for LISS) and all existing functionality is preserved.
