1. **Method Signature Update**: Added `bool active` parameter to `updateHint()` method across the display driver hierarchy:
- `DisplayManager::updateHint(x, y, active)` - delegates to driver
- `DisplayDriverTFT::updateHint(x, y, active)` - override implementation
- `DisplayDriverGFX::updateHint(x, y, active)` - override implementation
2. **Code Formatting**: `DisplayManager.h` reformatted (whitespace/comment style changes only)
- **Breaking Change**: All existing `updateHint(x, y)` calls will fail to compile until updated to include the `active` parameter
- **Enhanced Control**: Callers can now explicitly show/hide touch hints rather than just updating position, enabling better touch feedback UX (e.g., hide hint on touch release)
- **API Consistency**: All implementations in the driver hierarchy now enforce the same signature
1. **Added `active` parameter to hint animation**
- `updateHint()` now accepts a boolean `active` parameter across both display drivers (TFT and GFX)
- When `active=true`: faster pulse animation (500ms period) during active hold
- When `active=false`: slower pulse animation (2000ms period) during idle state
2. **Improved animation calculations**
- Replaced modulo operator with `fmodf()` for cleaner float calculations
- Standardized to `static_cast<uint8_t>()` for type conversions
- Fixed GFX driver to use `color565()` method instead of manual bit shifting
3. **Updated hint display logic**
- Now differentiates between "holding" state (fast pulse) and "idle" state (slow pulse)
- Hint draws at both states when `holdStartX >= 0` (touch position captured)
4. **Added code formatter task**
- New `mise.toml` task for running clang-format across all source files
- Users get **visual feedback differentiation**: fast pulsing during active hold vs. slow pulsing when idle
- More intuitive UI that clearly indicates whether a long-press is in progress or just waiting
- Cleaner, more maintainable code with standardized calculations and type conversions
