fix(depth-estimation): use --ignore-requires-python for Python 3.11 compat

The depth-anything-v2 PyPI wheel (0.1.0) declares python_requires>=3.12
but is pure Python (py3-none-any) and works on 3.11+. Updated SKILL.md
setup instructions and added a comment in requirements.txt so the
deployment agent uses the correct pip flags.
