What and why

Clears typescript:S6551 in editors/vscode/src/extension.ts: the extension version was read with String(...) over an unknown, which would have turned an object into [object Object]. The version is now used only when package.json declares a string and is empty otherwise, which is what every consumer of extensionVersion expects. No changelog fragment: the shipped package.json always declares a string, so no user-visible behaviour changes.

Deferred from this group: typescript:S107 and typescript:S3358 in src/webview/layout.ts, which #1336 edits; they land after that PR. The typescript:S2871 bug in src/webview/diagram.ts is already fixed on develop and leaves the next scan.

A pull request gets no SonarCloud analysis (the CircleCI scan job runs on develop and main only); the proof that these findings clear is the post-merge scan of develop.

How it was verified

npm test in editors/vscode passes (with client/node dependencies installed, as CI does); go test ./tests/hygiene passes. The SonarCloud analyzer run over the file reports no finding.

Checklist

• make test and make lint pass locally
• Tests added or updated for the change
• Documentation extended where it already covers the surface (see CONTRIBUTING.md)
• Changelog entry added as changes/unreleased/<slug>.<section>.md, not as an edit to CHANGELOG.md
• baselines regenerated and make docs-counts run if a gate count moved (compliance rows need nothing: the census is counted at docs build)
• No internal work-item labels (waves, slices, F4, K5) in the body, docs, or changelog
