Documentation Updates

Docs Added or Updated

• content/en/Guide/Development Workflow and Build System.md: Updated build environment documentation to reflect Rust toolchain usage
• content/en/Guide/Execution Tracing and Performance Analysis.md: Enhanced with clock cycle timestamp details

Buckyball Codebase Changes Covered

1. Rust Toolchain Integration (commit 9cd49a7)

   • Removed bebop submodule and related build configuration
   • Refactored build scripts to use Rust toolchain instead of bebop
   • Updated Nix flake to provide rustTools (rustc, cargo, rustfmt, clippy)
   • Removed bebop-specific test workloads

2. Tracing Enhancements (commit d39bea7)

   • Added NDJSON visualization script (bdb_ndjson_viz.py)
   • Added trace annotation script (bdb_ndjson_annotate.py)
   • Enhanced tracing with clock cycle support
   • Improved trace format to include precise timing information

3. Instruction Scheduler and Bank Alias Table (commit 0316193)

   • Existing documentation in Frontend Instruction Scheduling and Bank Aliasing.md already covers GlobalScheduler and BAT architecture
   • Verified content is current and accurate with recent implementation

Key Knowledge Gaps Addressed

• Clarified that Rust is now the primary toolchain for code generation and utilities
• Documented how clock cycle timestamps improve trace analysis precision
• Enhanced description of trace annotation and visualization tools for better developer understanding
