docs(ai): update

[KSXGitHub]

Summary

Updates the coding guidelines across documentation files to relax two Rust code style requirements that are no longer enforced or desired.

Changes

• Remove #[non_exhaustive] requirement for custom errors: Custom error types now only need #[derive(Debug, Display, Error)] without the #[non_exhaustive] attribute
• Remove #![deny(warnings)] requirement: Code is no longer required to be completely warning-free, allowing for more flexibility during development

Details

These changes were applied consistently across three documentation files:

• .github/copilot-instructions.md
• AGENTS.md
• CLAUDE.md

This aligns the documented guidelines with the actual project requirements and reduces unnecessary constraints on contributors and AI agents.

Benchmark 1: pdu
  Time (mean ± σ):     119.8 ms ±  36.4 ms    [User: 104.5 ms, System: 295.0 ms]
  Range (min … max):   104.7 ms … 210.9 ms    28 runs
 
  Warning: Statistical outliers were detected. Consider re-running this benchmark on a quiet system without any interferences from other programs. It might help to use the '--warmup' or '--prepare' options.
 
Benchmark 2: pdu-0.20.0
  Time (mean ± σ):     108.6 ms ±  19.1 ms    [User: 100.2 ms, System: 295.4 ms]
