fix: pin click<8.2 and typer<0.23 to resolve cel-agents dependency conflict

cel-agents 0.1.0 requires click<8.2,>=8.0.0. The previous unconstrained
`typer` spec resolved to typer 0.24.1 which requires click>=8.2.1 on
Python 3.10+, pulling in click 8.3.1 and causing the conflict warning.

- cli/requirements.txt: add click>=8.0.0,<8.2 and typer>=0.9.0,<0.23.0
- mcp_server/requirements.txt: same constraints

pip now resolves to typer 0.22.0 + click 8.1.8 with zero conflict
warnings. All 33 tests continue to pass.
