Subject: [PATCH] fix(ci): use PATH-based iverilog/vvp discovery for
 cross-layer tests

The default IVERILOG and VVP paths were hardcoded to macOS Homebrew
locations (/opt/homebrew/bin/iverilog). On Ubuntu CI runners, apt
installs iverilog to /usr/bin/, so the Path.exists() check returns
False and all Tier 2 Verilog cosim tests are silently skipped.

Change defaults to bare command names so the existing which-based
fallback at line 57-58 discovers the binary via PATH on any platform.
