Fix code quality issues by adding missing words to cspell dictionary

[Copilot]

The CI build was failing quality checks due to cspell reporting 27 unknown words across 5 files—all legitimate technical terms specific to VHDL simulators and project documentation.

Changes

Added 16 missing words to .cspell.json:

• Trace matrix documentation: tracematrix
• ActiveHDL simulator: vsimsa, alib, worklib, acom, asim, endsim
• ModelSim simulator: vlib, vcom, vsim, endsim
• Vivado simulator: nolog, xvhdl, runall, xelab
• System environment: PATHEXT

Note: Removed redundant uppercase VSIM entry—cspell handles case-insensitive matching via the lowercase vsim entry.
