docs: list __version__ in the Python README's API section

[dmccoystephenson]

Summary

• __version__ is listed in __all__ in python/src/github_docs/__init__.py but was absent from the API section of python/README.md, which is otherwise an exact match for __all__. A line has been added so the two lists are kept in symbol-for-symbol correspondence, as proposed in __version__ is exported from the Python package but is absent from the README's API list #9 (the smaller of its two options; the package's __all__ is left unchanged).

Half touched: python/ only, and only its README. No source, test, manifest, or workflow file is changed.

Test plan

• python/README.md API list compared line-by-line against __all__ in python/src/github_docs/__init__.py — every entry in __all__ now has a README line and vice versa.
• CI green on the PR head (docs-only change; the local test anchor was not run because the sandbox's interpreter is Python 3.8, below the package's 3.9 floor — recorded as UNVERIFIED-not-applicable since no anchor-covered file is modified).

Deferred this cycle

• 0.1.0 is unpublished on npm and PyPI, so 505 lines of forked GitHub-content code stay duplicated across two orgs #5 — publishing 0.1.0 requires registry credentials and a release decision that live outside this repository; not closable by a code change.
• PyPI trusted publishing is unconfigured, and this is the one release workflow with no dry_run to rehearse it #6 — the remaining steps (PyPI pending publisher, pypi/npm environments, distribution-name decision) are operator actions outside this repository, as already recorded in its deferral comment.

Closes #9

Self-review rubric (scored against the diff and the CI run on head 3ed8eaa):

• Scope: PASS — one file modified (python/README.md), one line added; nothing outside the __version__ is exported from the Python package but is absent from the README's API list #9 surface area is touched.
• Tests-new: no signal — no public method or function is added.
• Tests-fix: no signal — documentation correction, not a bug fix; there is no production behaviour to revert.
• Sibling structure: PASS — the new bullet follows the - \symbol` — description.` shape used by the surrounding API entries.
• Sibling renames: no signal — nothing is renamed.
• Docs: PASS — python/README.md API list now matches __all__ in python/src/github_docs/__init__.py entry-for-entry (8 entries each). README.md, js/README.md, both manifests, ci.yml, and js/src/index.ts are unaffected by this change.
• Issue resolution: PASS — __version__ is exported from the Python package but is absent from the README's API list #9 names exactly this gap and offers two resolutions; the first (add the README line) is implemented in full, and __all__ is deliberately left as it was.
• CI: PASS — all 8 legs (js 18/20/22, python 3.9–3.13) green on the PR head. The local anchor was not run (the sandbox interpreter is Python 3.8, below the 3.9 floor), recorded as UNVERIFIED-not-applicable because no anchor-covered file is modified.

Repo-specific items:

• No-leak (js) / Result-not-exception / No runtime dependency (js) / Export parity / Support-matrix parity: no signal — no js/ file or manifest is changed.
• No-leak (python): no signal — no GitHubDocsError message is added or changed.
• Stdlib-only: PASS — python/pyproject.toml is untouched; dependencies = [] stands.
• Sentinel intact: PASS — python/tests/test_client.py is untouched.

Out-of-diff observation: the phrase "matching pyproject.toml" in the new line is a claim that has to stay true by hand — __version__ in __init__.py and version in pyproject.toml are two literals with nothing tying them together. Both read 0.1.0 today. A release-time bump that touches only one would make the README's new line wrong; this is noted rather than fixed because a version bump is an owner decision and wiring the two together is not docs work.

No item scored FAIL; nothing to address in Phase 6.
