The example config now has the placeholder `/path/to/okf` for `command`, and the README explains
how to find the real path (`command -v okf` outside this project's environment). It also explains
why the bare name fails under `uv run`: it resolves to this framework's own okf 0.8.5, which has
no `mcp` command. A new pin asserts that the example's command is an absolute path; it was red at
daccdbe. The xfail smoke test stays as the measurement behind the rule.
Chose this over lifting the okf dependency to 1.1: it fixes the startup failure without a version
bump and without touching --prepass-payload.
