v7.1.1 — Intern-level seniority filter
Patch on v7.1.0.
- Seniority filter: the graph pipeline now drops clearly-senior roles (senior/staff/lead/principal/director/VP/chief) so only internship/junior/entry roles are scored and shown. Intern/graduate signals override (e.g. "Senior … Internship" passes).
- Applied in both the PreFilter node and job_ingestion (the read path used when acquisition is off).
- Effect: scored set ~413 -> ~288; no Senior/Staff/Lead titles in matches.
- 1195 tests passing.
