Implement the analyze overlaps CLI command, RPC endpoint, and ToolDef
to enable heuristic detection of visual overlaps, parent overflows, and
overlay patterns. Geometry computation now uses world-matrix visual
bounds to handle nested ancestor rotations and clipping frames correctly.
Update file-backed CLI commands to use Node fs/promises instead of Bun
runtime file APIs. This is required for the published CLI to function
when installed and executed in a standard Node environment. Add the
package.json subpath export to the core package for metadata consumers.
- Merge structural lint rules into oxlint.json and remove the second config file
- Add #tests/* path aliases and rewrite deep test helper imports
- Ban new deep parent-relative imports through the shared lint config
