Withdraws openstax_pl from main. It was never released: release: None, and it is not in the v0.2.5 tag.

Reason. On 2026-10-05, the "Cytowanie i udostępnianie" block on all 8 live /pages/przedmowa pages allows reuse only for non-commercial purposes. It also bars training large language models without OpenStax Poland's prior written consent. The OpenStax CMS lists all 8 Polish books as CC BY-NC-SA 4.0. The fetcher read only the foreword body and hard-coded CC-BY-4.0. Some pages contradict this: the block labels itself "(CC BY)", and the openstax.pl FAQ and catalogue say CC BY 4.0. The audit reads the terms as unresolved and restrictive, so we can't ship the books under a CC BY label. Audit references: artifacts/rights_audit_2026-10/reports/academic.md L3-9 and reports/citations/openstax_cv.md A1-A14.

What this PR removes

• data/openstax_pl/: 1,422 documents / 4,632,374 tokens, plus the sidecars, card and NOTICE.
• The src/sources.py entry. No legal-note stub is kept, unlike HPLT, because nothing was released.
• src/fetch_openstax_pl.py, src/test_openstax_contribution.py, src/openstax_requirements.txt and artifacts/openstax_pl_ontology_manifest.json (read only by that test). The fetcher would need rewriting before any re-add, and git history keeps it.
• The README row, the v0.2.6-dev total (now 1,330,455 / 1,257.8M), the main header (35 sources / 4,092,833 documents) and the contributor entry (14 further sources; PR #23 link dropped).
• The CHANGELOG line, which moves to "Removed from main". An entry is appended to artifacts/source_findings.md.

Checks

• python3 -m pytest from the repo root: 279 passed on a clean tree.
• render_sample.py: not applicable, since this is a removal with no shard to sample.
• python3 src/verify_paper_claims.py --tex ../polish-dynaword-v2/main.tex fails with LookupError: no table with \label{tab:s04-wersje} in the .tex. This is a known tooling gap (polish-dynaword-v2 #61). The source isn't in the paper or the v0.2.5 tag, so no paper count changes.
• src/make_docs.py was not used, because on current main it would rewrite the README's hand-maintained main and v0.2.6-dev sections. Docs were edited by hand.

Not fixed here. The README main header and "19 v0.2.5 sources still on main" totals (2,762,378) don't yet reflect PRs #49 and #50: 1000_novels −163 and wiktionary_examples −6,821 documents. That belongs in the release docs pass.
