- Steps can be executed individually without running previous steps
- Add missing 'import time' for _run_steps_worker
- Fix left panel layout: remove rowspan=2 to prevent overflow
- Left panel now correctly occupies only lower half of window
- Remove IP check from Step 1 environment check
- Add PS (ARM DAP) and PL detection to zynq_checker
- Log detailed JTAG chain information in Step 1
- Show PS/PL detection status in GUI logs
- Display JTAG chain devices with type classification
- Add zynq_checker.py module to detect Zynq devices on JTAG chain
- Connects to hw_server via Vivado batch mode
- Parses JTAG device names to extract part number (e.g. XC7Z100)
- Integrates into Step 1 environment check in main_window.py
- Shows JTAG status in header (JTAG: XC7Z100 ✓)
- vitis_checker: shutil.which() + xsct fallback for impact detection
- flash_programmer: _get_impact_path now checks xsct as fallback
- bitstream_programmer: _get_impact_path now checks xsct as fallback
- GUI: show '(via xsct)' alias note when xsct replaces impact
- ToolStatus: add 'alias' field for tracking which executable was found
- Fix 6 overlapping widget bugs in StepHeader (title/desc, btn/icon,
run/rerun) with proper 5-column grid layout
- Merge run/rerun buttons into single _action_btn with state-driven text
- Fix DARK_CARD NameError (undefined import → STEP_CARD_BG)
- Replace fragile vertical connector lines with full-width dividers

- Enlarge accent bar (4→5px) and buttons (28→32px)
- Simplify status text (Completed → Done)
- Improve connector line sizing and alignment
- Rename bit_path -> bootloader_bit_path for clarity
- Rename elf_path -> bootloader_elf_path for clarity
- Split single bin_path into bootloader_bin_path (flash) and
firmware_bin_path (TFTP upload)
- Reorder Configuration panel: BIT -> ELF -> Bootloader BIN ->
Firmware BIN
- Update display names with file extensions and context labels
- Update all step references (Step 2 flash, Step 3 bootloader,
Step 4 TFTP) to use new field names
