Add Company Classification Scanner pipeline

[warunkash]

Summary

• Implements a two-stage Company Classification Scanner that processes LinkedIn job results and removes staffing/recruitment firms while keeping product-based companies
• Combines a pre-built knowledge cache (80+ companies), keyword rules, HuggingFace zero-shot classification (facebook/bart-large-mnli), and an optional LLM agent orchestrator for 90–95% accuracy
• Runs fully offline for well-known companies — no API calls required

  ├─ Keyword rules          (fast, high-precision)
  ├─ HuggingFace bart-large-mnli (zero-shot NLI)
  └─ LLM Agent fallback     (openai-agents SDK / Anthropic)

Test plan

• Run python company_classifier/demo.py — should classify 12 companies correctly (5 product, 5 recruitment, 2 service)
• Verify Google/Amazon/Atlassian → Product Company
• Verify TekSystems/Randstad/ManpowerGroup → Recruitment Company
• Verify Accenture/Infosys → Service Company
• Enable use_hf=True and verify HuggingFace zero-shot path works for unknown companies
• Enable use_agent=True with an Anthropic API key and verify agent fallback triggers for low-confidence cases
