sailikhithk 6e1e315c02 fix: remove deprecated pathlib backport and migrate PyPDF2 to pypdf (#1029)
Remove pathlib==1.0.1 from ai_tic_tac_toe_agent/requirements.txt. This is the
abandoned 2012 backport of the stdlib module that can shadow and break Python's
built-in pathlib on modern Python. The code already uses `from pathlib import
Path` (stdlib), so the package is unnecessary.

Migrate PyPDF2 to pypdf in two projects (ai_recruitment_agent_team and
rag_chain). PyPDF2 is deprecated and had a ReDoS vulnerability (CVE-2023-36810).
The maintained successor is pypdf, which the rest of the repo already uses in
10+ other projects. The PdfReader API is identical:
  - import PyPDF2 -> import pypdf
  - PyPDF2.PdfReader -> pypdf.PdfReader

Files changed:
- ai_tic_tac_toe_agent/requirements.txt: removed pathlib==1.0.1
- ai_recruitment_agent_team/requirements.txt: PyPDF2==3.0.1 -> pypdf>=4.0.0
- ai_recruitment_agent_team/ai_recruitment_agent_team.py: import and usage
- ai_recruitment_agent_team/README.md: updated tech stack mention
- rag_chain/requirements.txt: PyPDF2 -> pypdf>=4.0.0
