• I have added tests that prove my fix is effective or that my feature works
  (if possible),
• I have made sure the CHANGELOG is up-to-date. All user-facing changes
  should be reflected in this document.

Summary by CodeRabbit

• Chores
  • Improved project maintenance checks for identifying unused dependencies and updated dependency configuration. These changes do not alter app behavior.
• Documentation
  • Clarified a serialization example; no runtime behavior changes.

Walkthrough

The pull request removes several direct Cargo dependencies and updates the ssr feature. It adds Cargo Shear to the lint tasks, configures an ignore entry for worker-macros, adds wasm-only imports for three getrandom versions, and changes a documentation example.

Changes: Dependency hygiene

Layer / File(s)	Summary
Dependency declarations and documentation Cargo.toml, src/utils/lotus_json/mod.rs	Removes async-trait, http, serde_tuple, and optional tower declarations. The ssr feature no longer enables http or tower. The documentation example presents serde_tuple::Serialize_tuple as code text.
Cargo Shear lint Cargo.toml, mise.toml	Excludes worker-macros from Cargo Shear checks. Installs cargo-shear 1.14.0 and runs cargo shear --deny-warnings as part of the aggregate lint task.
Wasm imports src/lib.rs	Adds wasm-only anonymous imports for getrandom versions 0.2, 0.3, and 0.4.

Priority: Low

Restore the direct async-trait dependency.

src/faucet/rate_limiter.rs uses #[async_trait::async_trait(?Send)] on two active declarations. The current manifest does not declare async-trait, so the SSR build can fail with an unresolved async_trait crate.

Suggested fix

 [dependencies]
 alloy = "2"
 anyhow = "1"
+async-trait = "0.1"
 axum = { version = "0.8", default-features = false, optional = true }
