chore: migrate chart_data_extractor and CI from Poetry to uv

[devin-ai-integration]

Summary

Replaces Poetry with uv, matching the E2B monorepo (uv 0.10.0, astral-sh/setup-uv@v6.8.0, uv_build backend).

• chart_data_extractor: [tool.poetry] → PEP 621 [project] + [dependency-groups] dev, with uv_build as the build backend. poetry.lock → uv.lock, generated with migrate-to-uv so every locked version stays the same (I diffed the name/version pairs across all 26 packages). Caret ranges are now explicit (^2.2.6 → >=2.2.6,<3).
  • license-files = ["LICENSE"] was added because Poetry included LICENSE automatically and uv_build does not. With it, the sdist and wheel contain the same files as the Poetry build.
  • package.json scripts switch from poetry … to uv …. postVersion is now uv version <v>, which also updates uv.lock. The release commit already runs git add -A, so the lockfile ends up in it.
• .tool-versions: poetry 2.1.1 → uv 0.10.0.
• Workflows: every setup-python + snok/install-poetry pair is replaced with setup-uv.
  • charts tests: uv sync --locked / uv build / uv run pytest
  • lint: uv sync --locked, and the global pip install ruff becomes uv tool install ruff==0.11.12
  • charts release: uv build && uv publish --check-url https://pypi.org/simple/ (this replaces --skip-existing). It still uses the CHARTS_PYPI_TOKEN secret, now passed as UV_PUBLISH_TOKEN, so nothing changes on PyPI.
  • template build jobs (test, prod, docker, release): setup-uv with activate-environment: true + uv pip install -r requirements-dev.txt. The python build_*.py steps are unchanged.

Not changed: the sandbox image itself (template.py still uses pip_install). No changeset, because the published e2b-charts package has no functional change.

Verified locally with uv 0.10.0: uv sync --locked, uv build, pytest (13 passed), ruff lint/format for both packages, uv version 1.0.1 → uv sync --locked still passes, and actionlint is clean.
