chore(release): 2.2.3, ECC-only naming in pi/core and a longer npm publish wait

pi/core and the bundled blueprint skill now refer to the project as ECC only;
the generated README no longer expands the name. Profile contents, package
name and paths are unchanged (123 skills, 24 commands).

The release workflows poll npm for up to five minutes after publish before
verifying the artifact. In 2.2.2 the check gave up after about 30 seconds while
npm was still processing, failing the run before latest was promoted and the
GitHub Release was created.

Version metadata synced to 2.2.3 with CHANGELOG, translated release headings
and release notes; skill-triggers registryDigest updated for the blueprint text.
