chore(sparrow-engine-python): bump 0.1.4 -> 0.1.5 for __version__ + README uv-venv fix

First prod-PyPI release carrying the two doc/API gap fixes that landed
in PW d25ca35:

- sparrow_engine.__version__ — single-sourced from wheel METADATA via
  importlib.metadata, tries 'sparrow-engine-gpu' first then
  'sparrow-engine', fallback 'unknown'. Adds the conventional Python
  introspection knob that was missing through 0.1.4.

- README §Python package only (PyPI) — split into 'With uv (recommended)'
  + 'With stdlib venv' subsections to fix the silent fall-through-to-
  system-pip failure when users follow the bare 'pip install ...' line
  inside a fresh uv venv (which doesn't ship pip).

0.1.4 wheels remain on prod PyPI as the last release without the
__version__ attribute. End-of-life behavior: importlib.metadata.version
keeps working as a fallback on 0.1.4; the attribute is purely additive.

Verified locally: built sparrow_engine-0.1.5-cp311-abi3 wheel, installed
into a fresh uv venv, 'import sparrow_engine; sparrow_engine.__version__'
returns '0.1.5'.

Tag v0.1.5 will fire the prod-PyPI publish CI (publish-pypi-cpu +
publish-pypi-gpu jobs, gated on non-prerelease tag push per
.github/workflows/release.yml:361 + :411).
