style: cargo fmt --all — make codebase rustfmt-clean

First run of the build-and-test CI gate (cargo fmt --all -- --check) surfaced
pre-existing formatting drift across the agent and server crates. Apply rustfmt
across the workspace so the codebase meets its own CI gate. Pure formatting; no
logic changes.
