feat: refactor NMI interface and remove unused variables

- Removed CORE and IP variables from common.tcl and synth.tcl scripts.
- Updated yosys.mk to exclude CORE and IP from environment variables.
- Modified bus_fault_tb to enhance NMI interface with management and user NMI signals.
- Added user access denial handling in bus_fault_tb.
- Updated pll_ctrl_tb and sysctrl_fault_tb to reflect changes in NMI interface.
- Adjusted test_gpio_user_mux.py to remove IP_MDD definition.
- Enhanced memory map tests to include user extensions and ensure proper generation.
- Updated test_script_tools.py to reflect changes in core management and user extensions.
- Refined topology tests to ensure user APB target is always added.
- Adjusted tech cell configuration tests to use simplified profile paths.
- Improved user extensions tests for scalar bindings and slot validation.

 # Reproducible Build Profiles
 
 This directory contains committed Make configuration profiles. Each profile
-selects SoC, CPU/IP, PDK, ISA, CSR support, application, linker layout, and
-the supported validation tier.
+selects SoC, PDK, ISA, CSR support, application, linker layout, and the
+supported validation tier. The user-extension fabric is fixed; the management
+core defaults to `HAZARD3` and may be set to `PICORV32` with `CORE`.
 
-`ci/` contains pull-request profiles, `nightly/` adds extended open-source
-coverage, and `cluster/` contains configurations requiring site tools or PDKs.
+`ci/` contains pull-request profiles and `cluster/` contains configurations
+requiring site tools or PDKs. The nightly workflow reuses the IHP130 CI profile.
 Start builds from a committed profile rather than setting an unreviewed mix of
 variables on the command line.
