CI: pin lint tools and format baseline

[ratulsarna]

This fixes the current CI failure where swiftformat Sources Tests --lint fails due to unpinned Homebrew tool drift.

What changed

• Pin lint tools in CI (SwiftFormat 0.59.1, SwiftLint 0.63.2) via Scripts/install_lint_tools.sh.
• Use a single entrypoint Scripts/lint.sh for lint / format.
• Route pnpm check through the pinned lint script.
• Apply the SwiftFormat baseline across Sources/ and Tests/.

Review notes

• Commit 1 is the functional CI/tooling change.
• Commit 2 is mechanical formatting only.

Commands run

• ./Scripts/lint.sh format
• ./Scripts/lint.sh lint
• swift test --parallel
• pnpm check
• ./Scripts/compile_and_run.sh --test

Yep — fixed.

tmp_zip no longer appends .zip onto mktemp output, so we don’t leave behind the extra unused temp file.
