feat: add sciCORE and Swisscom as job sources

sciCORE now runs inside bun fetch/daily via fetchSciCore instead of its
own standalone launchd watcher. Swisscom's Workday career site is added
as a new source (fetchSwisscom), pulled via its public CXS JSON API.

Also fixes a false positive in requiresGerman(): Swisscom's stock line
"proficiency in German is considered an advantage" was being flagged as
requiring German because the noun "proficiency" sat closer to the
mention than the real optional marker "advantage". A local-predicate
override now lets the words immediately following "German is/are ..."
decide the verdict instead of losing to raw character distance.
