Remove committed uv.lock so the env resolves the latest ogcore

[SeaCelo]

uv.lock was committed automatically during the conda→uv migration, and it pins ogcore to the migration-era 0.15.13. So the documented setup does not pull the latest ogcore — on main, uv sync installs 0.15.13 (and even downgrades a newer install) even though 0.16.1 is released.

git checkout main
uv sync --extra dev
uv run python -c "import ogcore; print(ogcore.__version__)"

This stops committing uv.lock, so uv sync resolves the pyproject floors freshly → latest compatible (ogcore 0.16.1 today, new releases as they land). pyproject.toml keeps the ogcore>=… floor for compatibility (what package consumers already use); the lock is regenerated locally and git-ignored.

• Removes uv.lock, adds it to .gitignore, updates the AGENTS.md convention.
• Verified: uv sync now resolves ogcore 0.16.1; pytest -m 'not local' passes (21).
• CI uses plain uv sync (no --frozen/--locked), so nothing breaks.
