fix(#6966): regenerate the example on the fixed Vertex profile

Rebased onto origin/main, which brings fullsend-ai/fullsend#6975 into
the generator's embedded scaffold: the Vertex profile now allows
`**/claude.exe` and `**/pi` alongside `**/claude`. On the v0.40.0 sandbox
image the Claude binary is `claude.exe`, so before that fix it matched no
profile's binaries list, no egress policy applied to it, and every
request it made was refused — which is what a local `--runtime claude`
run of this example hit.

The example's copied profile carries the fix now, and examples/README.md
gains the step that was missing for anyone trying to run one: these are
deliberately absent from this repository's config.yaml, so `fullsend
run` cannot resolve them until you register a copy. The exact error and
the `fullsend agent add` command that avoids it are both in the README —
found by hitting it.
