v0.30.0

[0.30.0] - 2026-05-04

Changed

• WorkoutData.resample(freq, interpolate=False) semantic downsampling behavior for lower-frequency buckets: cumulative fields (distance) use max; instantaneous fields (speed, power, heartrate, cadence, temperature, grade, elevation, enhanced_altitude) use mean; GPS coordinates (latitude, longitude) use mean; is_moving uses any. Accepts any pandas offset alias (e.g. "10s", "1min").
• Development tooling migrated from Poetry/Black to uv/Ruff: local and container workflows now use uv sync/uv run, linting uses ruff format and ruff check, and Poetry-specific artifacts/config (including poetry.lock) were removed.
• Contributor and project docs were updated for the uv workflow (CONTRIBUTING.md, README.md, docs landing page, and lab notebook setup instructions), and project automation guidance (Makefile, agent/copilot instructions) now reflects uv + ruff commands.
• Workspace defaults now pin Python 3.13 via .python-version and point VS Code to .venv as the default interpreter.

Fixed

• Fixed ValueError in elevation_smooth_time() for short recordings where the data length is less than the Savitzky-Golay filter's default window length (21). The function now gracefully degrades: recordings too short for any valid window are returned unsmoothed; recordings shorter than the default window use a reduced (but still valid) odd window length.
