Lint every workspace crate with all features

[isPANN]

Summary

• Run Clippy with --workspace --all-targets --all-features in CI and make clippy.
• Include CLI, macros, MCP, and benchmarks in the lint gate.
• Only two command/configuration files change; no source API or dependency changes.

Verification

• make clippy passed on the main-based branch with warnings denied.
• make -n clippy and git diff --check passed.
• Extracted from the updated source branch through 6f65416; independent of its recovery API changes.

[isPANN]

Consolidated into #1163 with dependency maintenance. The combined branch passes make clippy across the workspace with all targets and features.
