The 'Build, Test & Typecheck' job was failing immediately at its
first 'Pull latest' step with:
/opt/bytelyst/learning_ai_common_plat: No such file or directory
exit status 1
The act_runner on this host has the monorepo at
/Users/sd9235/code/mygh/learning_ai_common_plat (same pattern as
the consumer repos that switched to the on-disk workflow earlier
today). The legacy /opt/bytelyst/* path predates the migration and
never existed on this host.
Replaced all 10 occurrences across both CI workflow files
(.gitea/workflows/ci.yml and publish.yml) with sed. No script
content changed, only the cd target.
