docs: point repo links at the versioned /latest/ docs paths

Changes

File	Was	Now
README.md line 26	/get-started/	/latest/get-started/
README.md line 53	/tools/	/latest/tools/
README.md line 60	/get-started/#logging	/latest/get-started/#logging
CONTRIBUTING.md line 22	/dev/	/latest/dev/

Rationale

The documentation deploys with mike, which serves every page under a version
directory. The gh-pages root holds only a redirect to latest/. Unversioned
deep links therefore do not resolve to the intended page:

• /get-started/ returns 404.
• /tools/ returns 200, but serves the Sphinx page frozen at 2026-07-07. A
  directory from the pre-mike deployment still sits at the gh-pages root. A
  200 here does not mean the link is correct.
• /dev/ returns 200, but serves mike's dev version home page, not the
  development guide. mike's version name dev collides with the page
  docs/dev.md. The guide is at /latest/dev/.

This became visible only after
#201 was fixed. The site
had been serving a 2026-07-07 build, so no documentation URL resolved
correctly.

Not changed

Links to the bare root stay unversioned, because mike set-default --push latest writes the root redirect:

• README.md lines 4 and 16
• pyproject.toml Documentation
• CITATION.cff url

Verification

Every opensemanticlab.github.io/osw-python URL remaining in the repository
was fetched with curl. All five return 200. The #logging anchor resolves to
<h2 id="logging">Logging, the section describing OSW_LOG_LEVEL.

Related

• Docs site serves a build from 2026-07-07: mike deploys to gh-pages, Pages never rebuilds #201 - the Pages setting, now fixed and closed.
• Remove the pre-mike Sphinx directories from the gh-pages root #205 - removing the pre-mike Sphinx directories from the gh-pages root. Blocked until this PR merges, otherwise /tools/ turns from stale content into a 404.
