setup.py: put every supported runtime in the PyPI keywords

[vivekchand]

Why

Chasing down why the internet still calls this "ClawMetry for OpenClaw", the PyPI keywords turned out to be one of the upstream sources feeding it:

keywords="clawmetry openclaw moltbot dashboard observability ai agent monitoring opentelemetry"

Of 26 supported runtimes, the keywords named exactly two, and one of them is OpenClaw. The description field is already generated from runtime_count, so it self-heals on every release, but keywords is a hardcoded string and has not moved.

That matters because PyPI keywords drive PyPI's own search, and they get ingested by the package aggregators that then reprint our positioning. A developer searching PyPI for claude-code observability or cursor monitoring does not find us today.

What

Rewrites keywords to cover all 26 runtimes plus the category terms, as a wrapped tuple so it stays readable and diffs cleanly when a runtime is added.

No behaviour change, packaging metadata only.

Verify after release

curl -s https://pypi.org/pypi/clawmetry/json | python3 -c "import sys,json;print(json.load(sys.stdin)['info']['keywords'])"
