Summary

Adds _try_rerank() to job_ranker.py: after stack_score sort, reranks top-50 candidates by (resume, description) cross-encoder relevance using cf-core v0.15.0 reranker
Adds resume_text param to rank_jobs() — graceful no-op when empty, backward-compatible
Adds reranker gap-reordering pass in rewrite_for_ats(): gaps sorted by (jd_text, term) relevance before section grouping and LLM rewrite
Both integration points fall back silently on ImportError or inference failure
Tier model selection: CF_RERANKER_MODEL env var (Phase 2 Qwen3 hooks reserved)

Test plan

13 new tests in tests/test_reranker_integration.py — all passing
CF_RERANKER_MOCK=1 used throughout; no real model weights needed in CI
Full suite: 785 passed, 0 failures
Closes #108

Phase 2 / Phase 3 notes

make_reranker(model_id=...) API reserved for per-tier Qwen3 model selection (Phase 2)
cf-orch remote service profile slot already reserved in cf-core (Phase 3)

- Add _try_rerank() to job_ranker.py: after stack_score sort, rerank
  top-50 candidates by (resume_text, description) cross-encoder relevance
- Add resume_text param to rank_jobs(); graceful no-op when empty
- Add reranker gap-reordering pass in rewrite_for_ats(): gaps sorted by
  (jd_text, term) relevance before section grouping and LLM rewrite
- Both integrations fall back silently on ImportError or inference failure
- 13 new tests; CF_RERANKER_MOCK=1 for zero-weight test runs
- Closes #108
