OmniRoute PR and Coverage Instructions

Treat npm run test:coverage as a required gate for PR work.
The repository minimum is 60% for statements, lines, functions, and branches.
If a PR changes production code in src/, open-sse/, electron/, or bin/, it must include automated tests in the same PR.
When reviewing or updating a PR, if the report shows missing tests or coverage below 60%, do not stop after reporting the problem. Add or update tests in the PR first, rerun the coverage gate, and only then ask for confirmation.
Prefer the smallest test layer that proves the behavior:
- unit tests first
- integration tests when multiple modules or DB state are involved
- e2e only when the behavior is truly UI or workflow-dependent
For bug issues, try to encode the reproduction as an automated test before or alongside the fix.
In the final PR report, include:
- the commands you ran
- the changed test files
- the final coverage result
