Install Rust quality tools for pinned toolchain

[seonghobae]

Gap

The Security workflow installs rustfmt and clippy on stable, then the repository's rust-toolchain.toml selects pinned 1.97.1 for cargo fmt. The pinned toolchain lacks rustfmt, causing the Rust workspace gate to fail before any code checks run. This is reproduced in #1220's prior-head job 108109544836 and on other PRs.

Change

Install the components for the active pinned toolchain using rustup component add. Remove the ineffective rustup default stable override.

Verification

• actionlint .github/workflows/security.yml
• ../.venv/bin/python -m pytest -q tests/test_repository_security_metadata.py (14 passed)
• git diff --check

The hosted Rust job is the final validation boundary.
