* ci: daily Hacktoberfest 2026 prep tracker refresh (cron 11:50 UTC)
Adds .github/workflows/hacktoberfest_prep.yml (schedule: 50 11 * * *) and
scripts/hacktoberfest_prep_update.py. Each run:
- ticks tracked PR rows in docs/hacktober_2026_prep.md that are now
merged/closed (`[ ]` -> `[x]`),
- rewrites an 'Automated statistics' section with the current open issue and
open PR counts plus the top three directories with the most open
'awaiting reviews' PRs,
- exits non-zero once Hacktoberfest 2026 has begun (>= 2026-10-01), so the
prep window closing is loud and the job gets retired.
Standard library only; uses the Actions GITHUB_TOKEN. Refs #15081.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* style: wrap implicit string concatenations (ISC004)
* refactor: use httpx2 for API calls, drop unneeded future import
Address review feedback on the Hacktoberfest prep cron:
- Switch the tracker script from urllib to httpx2, the repo's standard
HTTP client, and add an install step to the workflow.
- Drop 'from __future__ import annotations' (unnecessary on Python >= 3.14t).

* Add a table of contents to DIRECTORY.md
Generate a linked table of contents of the top-level sections at the top
of DIRECTORY.md so readers can jump straight to a category, as suggested
in #13239 / #13111. The list is built in scripts/build_directory_md.py
(with a new md_anchor helper + doctests) so DIRECTORY.md stays fully
auto-generated.
* Address review: numbered ToC + link section headings to their directories
- Table of Contents is now a numbered list, so the final number shows the
total count of algorithm folders at a glance.
- Each top-level section heading links to its algorithm directory (e.g.
## [Sorts](sorts)), so clicking a section title jumps straight to the folder.
* 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

* 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)

* scripts: de-duplicate and harden the close_pull_requests_with_*.sh backlog jobs
Extract the five byte-for-byte-identical backlog-closing scripts into one
parameterized close_pull_requests_with_label.sh and make each named script a
thin wrapper. Addresses the recommendations from #15168:
- Correctness: filter by label server-side (gh pr list --label) instead of
listing all ~900 open PRs and matching client-side, so no PR is skipped by
an arbitrary --limit cap.
- De-duplication: one implementation removes the drift between copies (some
had sleep 2, one had it commented out, two had none).
- Throttling: a single, deliberate SLEEP (default 2s) between closes.
- Safety rails: set -euo pipefail, explicit --repo, and a DRY_RUN=1 preview
mode that prints what would close before a maintainer commits.
- Machine-readable summary (CLOSED_COUNT/CLOSED_PRS) so the Hacktoberfest
tracker can be updated from script output.
Follow-up to #15081.
