chore(asusctl): remove obsolete examples and dev-dependencies

[scardracs]

Description

This PR cleans up the asusctl crate by removing obsolete example scripts, test assets, and unused dev-dependencies.

Rationale:

• Obsolete Scratch Scripts: The files in asusctl/examples/ were created during early reverse-engineering of AniMe Matrix and Aura USB protocols.
• Dedicated Crates & Integration Tests: Core matrix transformations and LED packet logic are now properly implemented and maintained inside their dedicated crates (rog-anime, rog-aura) and covered by unit/integration tests.
• End-user CLI Focus: asusctl is a command-line binary for end users (/usr/bin/asusctl), not a published library crate, so cargo run --example is not used in production or packaging.
• Repository Hygiene: Removes ~300 KB of duplicate test media (PNG/GIF) and cleans up unneeded [dev-dependencies] in asusctl/Cargo.toml.

Summary of Changes:

• Deleted asusctl/examples/ directory (11 example .rs files and test media assets).
• Removed unused [dev-dependencies] from asusctl/Cargo.toml (png and redundant rog_dbus).

Verification and testing:

• I have performed a self-review of my code
• I have commented my code, particularly in hard-to-understand areas
• I have made corresponding changes to the documentation
• My code follows the style guidelines of this project (cargo fmt --all -- --check)
• My changes generate no new warnings (cargo clippy --all -- -D warnings/cargo check --all-targets)
• New and existing unit tests pass locally with my changes (cargo test --all)
• Cranky with 0 warning (cargo cranky)

📝 Walkthrough

Summary by CodeRabbit

• Chores

  • Removed legacy diagnostic, animation, lighting, and test-pattern example programs from the project.
  • Removed development-only package requirements associated with these examples.
  • Simplified build configuration and adjusted warning handling for smoother development builds.

• Impact

  • No changes to the main application’s user-facing features or supported device controls.

Walkthrough

The PR removes legacy Anime and Aura diagnostic examples, removes their development-only dependencies, and updates Cargo configuration to allow clippy::collapsible_if warnings.

Changes

Legacy example and build cleanup

Layer / File(s)	Summary
Remove device examples and unused dependencies asusctl/Cargo.toml, asusctl/examples/*	Removes the development-only rog_dbus and png dependencies and deletes legacy Anime, Aura, and fixture diagnostic examples.
Update Cargo lint configuration .cargo/config.toml	Retains the incompatible Rust version fallback resolver and adds a target-wide clippy::collapsible_if rustflag.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 1bce8

The cleanup is otherwise mergeable, but the accompanying build configuration broadly suppresses a clippy lint and could hide unrelated code-quality issues in other targets or future changes. Scope the suppression or remove it with explicit owner awareness.

Scope the clippy::collapsible_if allow to the affected code.

cfg(all()) applies this suppression to every target. It hides the lint in unrelated crates and in future code. Remove the global flag, fix the affected conditionals, or add an item- or module-level #[allow(clippy::collapsible_if)] only where required.

Proposed fix

-[target.'cfg(all())']
-rustflags = ["-A", "clippy::collapsible_if"]

📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change

	[target.'cfg(all())']
	rustflags = ["-A", "clippy::collapsible_if"]
