chore(10027-cheatcode-mutability-tags): Fix Mutability Tags for Cheatcodes that are Missing Them

[Mouzayan]

Summary

Opening this as a draft to track work and get feedback.

This draft PR begins addressing issue #10027 — reviewing and updating view / pure / external modifiers for cheatcodes that do not modify EVM state.

Plan

• Identify cheatcodes currently marked external with no view or pure modifier
• Evaluate whether they:
  • Mutate observable state (EVM, filesystem, logs, interpreter) → leave as-is
  • Depend on prior cheatcode state but don’t mutate → mark as view
  • Have no dependencies or side effects → mark as pure
• Update their ABI and signature accordingly
• Add or update tests or dev docs if needed

Note

Ran cargo check, cargo clippy, and cargo +nightly fmt --check, all passed.
Ran cargo test --all --all-features multiple times and observed inconsistent failures across different tests.

To verify test isolation, ran: cargo test --all --all-features -- --test-threads=1.
With this, previously failing tests (like decode_traces_with_project_artifacts) passed, possibly indicating test suite flakiness.
