What and why

Clears the seven SonarCloud code smells on develop in editors/vscode/src/landing/main.ts:

• typescript:S7755 (1263) — the last trace record is read with steps.at(-1).
• typescript:S3358 (1264) and typescript:S4624 (1266) — the action status's ending is an if/else if, and the outputs suffix and the token noun are named locals instead of a nested ternary inside nested template literals.
• typescript:S3358 (1397) — the three-way ternary that ran a scene program is a runProgram switch on program.kind.
• typescript:S3358 (1407, 1408) and typescript:S4624 (1408) — the status subject (over …) is a runSubject switch on program.kind, with the action's event suffix as its own local.

Both switches cover every SceneProgram kind (journey and rollup share the former fallback branch), so TypeScript checks their exhaustiveness through the return type. Every status string is unchanged. Pure refactor, no changelog fragment.

How it was verified

• editors/vscode: npm ci, npm run build, npm run typecheck, npm test — 456 pass, 0 fail
• SonarQube analyze_code_snippet (ts) on develop and this branch reports none of S7755/S3358/S4624 for this file on either side (the analyzer's profile does not reproduce them), so the seven sites were checked by inspection: no .length - 1 index, no nested ternary, no nested template literal remains in the changed functions.

Checklist

• make test and make lint pass locally (editors/vscode build, typecheck and tests)
• Tests added or updated for the change (n/a: refactor; existing landing tests cover the status text)
• Documentation extended where it already covers the surface (n/a)
• Changelog entry added (n/a: refactor only)
• baselines regenerated (n/a)
• No internal work-item labels in the body, docs, or changelog
