feat: add CLOB_HOST constant (#30)

[MackDing]

Closes #30

Adds CLOB_HOST = "https://clob.polymarket.com" to py_clob_client_v2/constants.py and re-exports it from the top-level package so users can do from py_clob_client_v2 import CLOB_HOST rather than redefining their own.

Verification

$ python -c 'import importlib.util; spec=importlib.util.spec_from_file_location("c","py_clob_client_v2/constants.py"); m=importlib.util.module_from_spec(spec); spec.loader.exec_module(m); print(m.CLOB_HOST)'
https://clob.polymarket.com

Files changed

• py_clob_client_v2/constants.py — define CLOB_HOST
• py_clob_client_v2/__init__.py — re-export and add to __all__

---

Note

Low Risk
Additive constant and public export only; no runtime or API behavior changes.

Overview
Adds a shared CLOB_HOST (https://clob.polymarket.com) in constants.py and re-exports it from py_clob_client_v2 so callers can import the official CLOB base URL instead of duplicating it locally.

No client or request behavior changes—only a new public constant.

Quick follow-up: I merged the latest main into this branch and resolved the export conflict in py_clob_client_v2/__init__.py. I verified the touched module with python3 -m py_compile py_clob_client_v2/__init__.py; full pytest could not be run locally because poly_eip712_structs==0.0.1 was not resolvable from PyPI in this environment. From my side the remaining blocker appears to be maintainer review.

[MackDing]

Checking in on this PR. It is still open and appears to be waiting on maintainer review.

I am happy to adjust the scope or add verification details if that would make review easier.

[MackDing]

Refreshed this PR against the current main with a non-rewriting merge commit.

Verification on the merged tree:

• python -m pytest -q: 227 passed
• top-level import check: from py_clob_client_v2 import CLOB_HOST
• verified CLOB_HOST == https://clob.polymarket.com

The final PR diff remains limited to defining CLOB_HOST in constants.py and re-exporting it from __init__.py. PR #80 was also closed by its author in favor of this earlier contribution.
