Restore Rust formatting compliance for origin/main

Run cargo fmt across the Rust workspace after rebasing onto origin/main so the branch matches rustfmt's current output and the CI formatter gate can pass again. This commit intentionally contains formatter output only and keeps it separate from the README brand refresh.

Constraint: origin/main was failing cargo fmt --all --check
Rejected: Manually format only the initially reported files | cargo fmt --all updated additional workspace files that are part of the formatter gate
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Do not mix behavior edits into formatter-only commits
Tested: cargo fmt --all --check
Tested: cargo test --all
Tested: git diff --check
