Introduces support for Xilinx ISE build flow

Adds scripts and utilities for synthesis, mapping, placement, and bitstream generation using Xilinx ISE tools. Refactors configuration management into a dedicated module. Updates project model to support tool-specific options. Adjusts `.gitignore` and Python version compatibility.

Simplifies directory handling and ensures modularity by reorganizing configuration and tool logic.
