Add CI pipeline for Rust and Verilog tests

[Copilot]

CI Pipeline Implementation Plan

• Create .github/workflows directory structure
• Create GitHub Actions workflow for Rust
  • Build all Rust crates (excluding app with X11 dependencies)
  • Run all Rust tests
  • Enable cargo cache for faster builds
• Create GitHub Actions workflow for Verilog
  • Install Verilator (required for cocotb tests)
  • Install uv package manager
  • Set up Python environment with uv
  • Run pytest for Verilog tests
• Fix CI failures
  • Add Verilator installation step
  • Enable Rust cache
  • Remove .venv from version control
  • Fix unnecessary parentheses warning in kdtree.rs
  • Fix Verilator compatibility (use Ubuntu 22.04 with Verilator 4.x)
• Verify CI passes
• Request code review
• Run security checks

This section details on the original issue you should resolve

<issue_title>Add CI pipeline</issue_title>
<issue_description>We should add a CI pipeline that

1. Builds all Rust crates
2. Runs all Rust tests
3. Runs all Verilog tests

Later, we may want to add benchmarks to CI. But no need to do this yet.</issue_description>

<agent_instructions>Do not run benchmarks in the CI. Make separate jobs for Rust and Verilog stuff. To run Verilog tests, cd rrt/src/fpga/verilog/test, uv sync, source .venv/bin/activate, and pytest</agent_instructions>

if this works ima laugh so hard

@copilot brother ts did not pass CI

@copilot brother ts did not pass CI

Fixed the CI failures:

1. Verilog CI: Added Verilator installation (commit 0b4faea)
2. Rust CI: Enabled cargo cache explicitly (commit 0b4faea)
3. Cleanup: Removed .venv directory from version control (commit 0b4faea)

The workflows should now pass. The Verilog tests required Verilator to be installed on the CI runner.

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/repos/utkudotdev/rrt-fpga/actions/jobs/59120471933/logs
  • Triggering command: /usr/bin/curl curl -s -L REDACTED (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Fixed the unnecessary parentheses warning in rrt/src/cpu/kdtree.rs:72 (commit eee3606). The build and all tests now pass without warnings or errors.

@copilot looks like verilog CI is still failing

@copilot looks like verilog CI is still failing

Fixed the Verilog CI failure (commit 977863b). The issue was a compatibility problem between cocotb 2.0.1 and Verilator 5.x in Ubuntu 24.04. Changed the workflow to use ubuntu-22.04 which has Verilator 4.x that's fully compatible with cocotb.
