Cycling workouts with percentOfMaxHr intensity are skipped during conversion

[andrebbruno]

Description

Cycling workouts from TrainingPeaks that use percentOfMaxHr as the intensity type fail to convert and are skipped entirely. The workout structure (steps) arrives empty in Intervals.icu, while the workout name and description are imported correctly.

Running workouts using percentOfThresholdPace convert successfully with full step structure.

Error from logs

WARN o.f.t.i.p.t.w.TPToWorkoutConverter: Error during TP Workout conversion, skipping, 
  id: 3607857857, name: Bike Ritmo e Vo2 Max., error - Cant convert intensity percentOfMaxHr

Root cause

TPTargetMapper.kt only maps three intensity types:

• percentOfFtp → FTP_PERCENTAGE
• percentOfThresholdHr → LTHR_PERCENTAGE
• percentOfThresholdPace → PACE_PERCENTAGE

percentOfMaxHr (percentage of max heart rate) is not in the map. When getByIntensity() encounters it, it throws an IllegalArgumentException and TPToWorkoutConverter catches it and skips the entire workout.

Proposed fix

Add MAX_HR_PERCENTAGE support across 3 files:

1. WorkoutStructure.kt — add enum value:

enum class TargetUnit {
    FTP_PERCENTAGE,
    LTHR_PERCENTAGE,
    PACE_PERCENTAGE,
    MAX_HR_PERCENTAGE,
}

2. TPTargetMapper.kt — add mapping:

WorkoutStructure.TargetUnit.MAX_HR_PERCENTAGE to "percentOfMaxHr",

3. ToIntervalsStructureConverter.kt — add output format:

WorkoutStructure.TargetUnit.MAX_HR_PERCENTAGE to "% HRmax",

Environment

• tp2intervals version: 0.12.3
• TrainingPeaks workout type: Cycling (Ride)
• Intensity type in TP: percentOfMaxHr

I have a working fix in a fork: https://github.com/andrebbruno/tp2intervals/tree/fix/add-percentOfMaxHr-support
