chore: apply cargo fmt across workspace and update docs

- Run cargo fmt on all Rust crates for consistent formatting
- Update CLAUDE.md with WASM plugin commands and dev.ps1 instructions
- Update wiki: add WASM plugin architecture, rewrite dev environment docs
- Minor frontend cleanup (unused imports)
