fix(publish): simplify publish script to prevent CI hangs (#506)

* fix(publish): simplify publish script to prevent CI hangs

Remove redundant check/build logic from publish script. The ci:validate
script already runs tests, checks, and builds before publish:ci runs.
The publish script now only validates artifacts exist and publishes.

This fixes potential CI hangs caused by running tests with piped stdio.

* style: ignore openapi.json from formatting

The auto-generated openapi.json file was causing inconsistent formatting
between local and CI environments. Since it's auto-generated, exclude it
from formatting.
