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.
- Remove stale imports and unused locals from split engine and e2e tests
- Drop the targeted no-unused-vars test allowances
- Keep check and affected test suites warning-free
- Re-enable duplicate imports, radix, prefer-const, nested ternary, and silent catch checks in tests
- Drop the redundant spec-file override covered by the broader test override
- Fix the remaining test offenders surfaced by the stricter rules
- Move top-level engine and e2e prefixed test files under domain folders
- Update fixture path helpers after moving render and pen tests
- Add lint coverage to prevent new top-level prefixed test files
- Refresh testing docs for the new fig and layout paths
