Lataa icuvisor 1.6.3

### Added

• Structured workout steps now accept `press_lap：true`, which serializes the documented Intervals.icu `Press lap` marker while retaining a required duration or distance for planned load estimates. The workout-syntax resource documents Garmin-focused device support and fidelity warnings remain explicit when the returned workout document omits the control.
• `get_extended_metrics` now returns eight running-dynamics metrics at activity and interval scope when present：stance time, vertical oscillation and ratio, step length, stance-time percent and balance, vertical speed, and leg-spring stiffness. Responses preserve explicit units and source provenance, omit absent/null/malformed values, and retain zero values. `average_impact_loading_rate` remains raw-only because its unit is not documented.

### Changed

• Disabled automatic Winget manifest submission until the fork token can execute `UpdateRef`; the manual recovery workflow remains available.

### Fixed

• Regenerated the tool-input schema snapshots after adding structured-workout `press_lap` support, restoring the schema freshness CI guard.
