Implements automatic stitch rollback on thread errors (upper thread: -6,
lower thread: -2, sewing start: -21) and manual step controls to adjust
stitch position when machine is paused/stopped/interrupted. Adds UI with
step buttons (-100/-10/-1/+1/+10/+100), thread start jump, and current
stitch reset. Uses existing NEEDLE_MODE_INSTRUCTIONS (0x0709) BLE command.

The application now properly detects when a Brother PP1 machine is not paired with the operating system. Previously, the connection would appear successful but commands would fail silently.
Changes:
- Enhanced sendCommand() to check for empty or invalid responses during initial connection
- Updated connect() to validate the connection with a test command (getMachineState)
- Properly disconnect and clean up when pairing is not established
- Throw BluetoothPairingError with helpful instructions for the user
When the machine is not paired, users now see a clear error message instructing them to:
1. Long-press the Bluetooth button on the machine
2. Pair via the operating system's Bluetooth settings
3. Try connecting again

- Add lock stitch rotation based on movement direction (matches C# PesxToPen.cs)
- Calculate direction by accumulating vectors up to 5 stitches or 8.0 units
- Scale direction vectors from magnitude 8.0 down to 0.4 for proper lock stitch size
- Generate 8 lock stitches (not 4) alternating between +dir and -dir
- Remove PyStitch duplicate position stitches during color changes
- Add long jump detection with automatic lock stitches and cut commands
- Improve color change sequence: finish locks, cut, jump, COLOR_END, start locks
- Parse PEN data to get actual stitches for rendering (fixes jump stitch colors)
- Add encodeStitchPosition() helper function for coordinate encoding
- Improve pattern info refresh timing after mask trace
- Add detailed logging for PEN encoding and pattern info responses

Detect when device is not paired at OS level and handle automatic disconnections. The app now properly updates UI state when the device is disconnected by the OS.
Changes:
- Add BluetoothPairingError custom error class in BrotherPP1Service
- Track isInitialConnection state to differentiate pairing issues from disconnects
- Detect pairing issues in sendCommand() only during initial connection
- Add onDisconnect() subscription method to BrotherPP1Service
- Listen for 'gattserverdisconnected' events and update state automatically
- Add isPairingError state to useBrotherMachine hook
- Display pairing errors with blue info styling instead of red error styling
- Include step-by-step pairing instructions: long-press Bluetooth button on machine, then pair in OS settings
- Automatically reset connection state when device disconnects

Previously, isPolling was manually set in individual refresh functions,
which didn't cover all BLE communication and could have race conditions.
Now the communication indicator is driven by the service layer:
- Added isCommunicating state to BrotherPP1Service
- setCommunicating() called at queue processing boundaries
- onCommunicationChange() callback subscription pattern
- Hook subscribes to service communication state automatically
Benefits:
- Indicator shows for ALL BLE commands (status, progress, service count, etc)
- Prevents race conditions from overlapping command queue processing
- More accurate representation of actual BLE communication
- Cleaner code - no manual setIsPolling in each function
The indicator now properly shows whenever the command queue is being
processed, regardless of which specific command triggered it.

Implement support for fetching and displaying the machine's cumulative
stitch statistics using the SERVICE_COUNT (0x0100) command.
The SERVICE_COUNT command returns two uint32 values:
- serviceCount: Cumulative service counter
- totalCount: Total stitches sewn by the machine (lifetime)
Changes:
- Add serviceCount and totalCount fields to MachineInfo interface
- Implement getServiceCount() method in BrotherPP1Service
- Call getServiceCount() when fetching machine info on connect
- Display "Total Stitches" in Machine Connection panel
- Format stitch count with locale-specific thousand separators
- Handle errors gracefully if SERVICE_COUNT command fails
The total stitch count is now visible in the Machine Connection section,
providing users with insight into their machine's lifetime usage.
