dbc parser skeleton

A minimal DBC parser skeleton for the FrameTap project.

The purpose of this module is to read a DBC file and convert it into a simple internal representation that can later be:

• displayed as a tree
• connected to Qt Model/View
• used for signal selection
• extended toward runtime CAN frame decoding

---

Overview

The architecture is intentionally simple:

1. dbc_parser reads a DBC file
2. parsed data is stored in DbcDatabase
3. dbc_tree_builder converts it into a TreeNode hierarchy
4. the resulting tree can later be adapted to QAbstractItemModel

This keeps the parser independent from Qt and makes it easier to test and evolve.
