fix: concurrent cache miss, SVG output, narrowed error handling, format

- Fix integration data cache: check pending promise before TTL to
  prevent returning undefined on concurrent cold-cache access
- Add concurrent-miss test (two parallel callers, one fetch)
- SVG sanitizer: extract <svg> from DOMPurify output to strip
  residual HTML wrapper
- Narrow safeRevalidateTag catch: log unexpected errors, silence only
  known "outside request scope" messages
- Run oxfmt across all packages (206 files formatted)
