feat: add NVC

[rinagm]

This Pull Request adds NVC support to TerosHDL as both a VHDL linter and standalone simulator, following the existing architecture used for the GHDL integration wherever possible.

• Added support for NVC as a VHDL linter (src/colibri/linter/nvc.ts).
• Added support for NVC as a standalone VHDL simulator.
• Implemented the NVC backend (executor, commandBuilder, tasks, taskRunners, and utils) following the same design pattern used by the existing GHDL implementation.
• Added support for the NVC task workflow (Analyze, Elaborate, Simulate, and Run All).
• Integrated NVC into the graphical interface and configuration system.
• Added NVC as an available VHDL linter option in the settings.
• Added the required configuration files and types for NVC.
• Updated the task tree to expose the NVC simulation workflow.
• Added automated tests for both the linter and simulator integrations: tests/nvc/nvc_linter.spec.ts, tests/nvc/nvc_simu.spec.ts
• Added the corresponding configuration UI generation for the Tools and Linter sections (src/colibri/config/config_web.ts).
