* deps: migrate from httpx to httpx2 (pydantic's maintained fork)
Mechanical rename of httpx -> httpx2 (API-compatible fork of httpx 0.28.1):
pyproject.toml deps, PEP 723 inline-script headers, and all import/call sites.
Excludes uv.lock (the keeper's allow-list rejects .lock files); the lock
refresh needs a separate maintainer-merged PR.
Refs #15081
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* deps: drop tweepy + migrate remaining requests refs to httpx2
- maths/allocation_number.py: docstring example uses httpx2, not requests
- web_programming/get_imdbtop.py.DISABLED: import httpx2 instead of requests
- remove web_programming/get_user_tweets.py.DISABLED (a Twitter API how-to,
not an algorithm) and drop the tweepy dependency that was its only user and
the last high-level dep pulling in requests
- uv.lock intentionally untouched (keeper allow-list)
