chore: bump click version

[DRMPN]

Why

• Click version 8.1.7 was released on August 17, 2023, while version 8.2.0 became available on May 15, 2025.
• Several modern packages now depend on Click 8.2.0 or newer, creating incompatibilities with ProtoLLM’s current requirement of Click 8.1.7.

For example marker-pdf package:

Because marker-pdf (1.10.1) depends on click (>=8.2.0,<9.0.0)
 and protollm (0.1.5) depends on click (8.1.7), marker-pdf (1.10.1) is incompatible with protollm (0.1.5).
So, because osa-tool depends on both ProtoLLM (0.1.5) and marker-pdf (1.10.1), version solving failed.

If this change is acceptable, it would be great if you could publish a new version of ProtoLLM to PyPI.
