docs: the documents describe smart-data-engine-sdk 0.1.1; main moves to 0.1.2.dev0

[krzysztof-smartdataengines]

Summary

smart-data-engine-sdk 0.1.1 is on PyPI, and npm keeps 0.1.0. The documents that describe
registry state now say so. Python's development version moves to 0.1.2.dev0. TypeScript was not
released and stays on 0.1.1-dev.0.

What changed

• Install commands in docs/weather-starter.md pin 0.1.1 from PyPI and 0.1.0 from npm.
  The artifact names are the ones a later commit builds. README.md and
  examples/weather/README.md name the current releases.
• docs/implementations.md: pip install installs 0.1.1, and npm install installs 0.1.0.
• CHANGELOG.md: the publication date. python-v0.1.1 published on its first run, with
  attestations.
• docs/publishing.md:
  • §5.1 says a release of one language moves only that language on.
  • §5.5 gets step 8, the first patch release, with a correction to the rule written for 0.1.0.

The correction

The rule for 0.1.0 said to pin the version when verifying right after a publish. For 0.1.1, a pinned
pip install 'smart-data-engine-sdk==0.1.1' --no-cache-dir started 41 s after the upload
answered "No matching distribution found". It saw only 0.1.0rc1 and 0.1.0. The simple index
listed 0.1.1 70 s after the upload, and it is served with cache-control: max-age=600.

pip resolves a pinned version from that same index, so pinning is not the fix. Right after a
publish, the files are verified against the gate's artefacts through the JSON API. Installs,
pinned or not, wait until the simple index lists the version.

Verified from PyPI before this PR

• The wheel and the sdist are the artefacts the gate checked, each with a PEP 740 attestation from
  release.yml and the pypi environment.
• The pinned install from the index carries the fix.
• The suite of 99c1ed7 against the installed package, with both engines, on CPython 3.14.7:
  2098 passed, 10 skipped, 5 failed. The five are the ones 0.1.0 failed, each computing a repository
  path from sde.__file__. fix(operator): index recovery waits for the interrupted PostgreSQL statement #100's two recovery tests passed against the installed package.
• The Weather model version is 794ff972d69c52e5 from PyPI 0.1.1 (pinned and unpinned) and from
  npm 0.1.0 on Node 18 and 26.

Tests

make check with both live engines on f86353e (this head):

• ruff and mypy are clean;
• Python: 2103 passed and 10 skipped (the orderbook slice);
• TypeScript: 999 of 999.
