chore: update package.json scripts for improved type-checking
fix: adjust frontmatter regex to handle BOM characters
refactor: streamline error handling in dashboard data conversion
style: clean up comments and formatting in various files
## What changed
Fixed three issues in the Trace Graph:
- **Multi-root traces no longer crash** — traces where root spans
belonged to distinct services, the same service, or had cyclic service
relationships now render correctly instead of showing an empty graph.
- **Overlapping node labels are truncated** — long service names in
chart nodes are capped at 24 characters with an ellipsis, preventing
overlap with the next tree level.
- **Tooltip now shows the service name** — the pattern node tooltip
header was missing the service name, making it impossible to seethe full
name of a truncated node on hover.
Also added `truncateText` utility to `zincutils.ts` and comprehensive
test fixtures covering all multi-root scenarios.
