Polish packaging extras and install docs

[chiruu12]

Summary

• Fix wrong PyPI package name in Firecrawl docstring (unplug-ai[scrape]); widen transformers to >=4.44,<6
• Drop published dev optional-extra (pytest/ruff moved into the dev dependency-group for uv sync --dev)
• Document Atomic Agents Python ≥3.12 install gate and Semantic Kernel pybars4 wheel-only constraint
• Add CI packaging-ml-wheels job: wheels-only resolve of unplug-ai[ml] on Python 3.13

Test plan

• make check (1113 passed)
• make test-cov (85%+, gate met)
• uv pip compile --python-version 3.13 --extra ml --no-build succeeds locally
• CI green on this PR (incl. new packaging-ml-wheels job)

Note

Low Risk
Changes are packaging, CI, and documentation; widening transformers is the only user-facing dependency shift and is low risk for typical installs.

Overview
Packaging and install ergonomics: pytest/ruff are removed from the published dev optional-extra and moved into the uv dev dependency-group (uv sync --dev). The transformers constraint for [ml] is widened to >=4.44,<6. Firecrawl’s module docstring now says unplug-ai[scrape].

CI: On Python 3.13, the main SDK job skips ml/litellm during uv sync (lighter matrix) and uses --dev instead of --extra dev. A new packaging-ml-wheels job runs uv pip compile --extra ml --no-build on 3.13 to catch wheel-only / sdist breakage without downloading torch. Integrations (live) installs ".[<extra>]" --group dev so pytest comes from the group, matching the dropped PyPI dev extra.

Docs: Atomic Agents README documents the Python ≥3.12 extra marker; Semantic Kernel README notes pybars4 sdist-only installs fail under --no-build. integrations/TESTING.md and CHANGELOG are updated accordingly.

Greptile Summary

This PR polishes SDK packaging metadata, CI install checks, and install guidance. The main changes are:

• Moves test and lint tooling from the published dev extra into the uv dev dependency group.
• Updates CI and integration docs to install framework extras with the dev dependency group.
• Adds a Python 3.13 wheel-only resolve check for the ml extra.
• Widens the transformers range for the ml extra.
• Updates install notes for Firecrawl, Atomic Agents, and Semantic Kernel.

Confidence Score: 5/5

This looks safe to merge.

• No blocking issues found in the changed code.
• The changed CI and integration install paths now use the dev dependency group instead of the removed published extra.
