Add CI minimal install tests and optional plotting import

[cmungall]

Summary

Improve release quality and installation experience by:

1. Adding CI tests for minimal (no extras) installs
2. Adding pre-flight tests before PyPI release
3. Making plotting imports optional
4. Adding ADBC driver to dremio extra for faster queries

Problem

Users running uvx linkml-store --with dremio hit ImportError for matplotlib because:

• CLI unconditionally imports plotting module
• No CI tests verify minimal installs work
• Release workflow publishes without testing

Changes

CI: Add minimal dependency test job

.github/workflows/main.yaml

• New test-minimal job runs BEFORE full test suite
• Tests with NO extras installed
• Verifies linkml-store --help and basic imports work
• Catches accidental hard dependencies on optional packages

Release: Add pre-flight tests

.github/workflows/pypi-publish.yaml

• Run critical tests before building wheel
• Test minimal install viability in fresh venv
• Prevents broken releases reaching PyPI

CLI: Optional plotting import

src/linkml_store/cli.py

• Wrap plot_cli import in try/except
• Only add plot command if matplotlib available
• Graceful degradation instead of crash

Dependencies: ADBC for Dremio

pyproject.toml

• Add adbc-driver-flightsql to [dremio] extra
• Enables faster Arrow Flight SQL with connection caching
• First query ~10s (connection), subsequent queries ~0.05s

Testing

# Test minimal install locally
uv venv /tmp/test-minimal
source /tmp/test-minimal/bin/activate
pip install -e .  # no extras
linkml-store --help  # should work without matplotlib

Pull request overview

This PR aims to improve the installation experience and release quality by adding CI tests for minimal installs, making plotting imports optional, and adding ADBC driver support for Dremio. The primary motivation is to fix ImportError issues when running uvx linkml-store --with dremio without matplotlib installed.

Changes:

• Added CI job (test-minimal) to verify minimal installs work without optional dependencies
• Added pre-flight tests in the release workflow to catch issues before PyPI publication
• Made the plot CLI command optional by wrapping its import in try/except
• Added adbc-driver-flightsql to the dremio extra for faster Arrow Flight SQL queries

The "all" extra is missing "plotly" which is included in the "analytics" extra (line 41). Since the "all" extra should include all optional dependencies, it should also include "plotly". This is inconsistent with the analytics extra definition.
