fix: correct realpath path and OIDC token variable in publish workflow

[Farenheith]

Summary

Fix two bugs in the sequential publish pipeline that caused CI failure:

1. realpath path bug: realpath ".${lib_path}" failed because ${lib_path} includes trailing slash (e.g., libs/augmentative-iterable/), resulting in .libs/... which doesn't exist. Fixed to realpath "./${lib_path}".

2. OIDC token corruption: The variable ${ACTI...KEN} was corrupted instead of ${ACTIONS_ID_TOKEN}, causing OIDC token exchange to fail silently (returning null).

Error

realpath: .libs/augmentative-iterable/: No such file or directory
Error: Process completed with exit code 1.

Fix

• Line 96: realpath ".${lib_path}" → realpath "./${lib_path}"
• Line 80: ${ACTI...KEN} → ${ACTIONS_ID_TOKEN}

Build & lint

All passing on the branch.
