test: trim scheduled e2e matrix and harden dev-server process cleanup

Scheduled Monday e2e run now targets 6 priority suites covering CodeZip,
Container, custom JWT auth, evals, import, and local dev paths. Manual
workflow_dispatch still runs the full e2e directory to exercise every
framework/model-provider combo. Halves weekly AWS test burn from 6 shards
of the full suite to 6 shards of the priority subset.

Replace fire-and-forget SIGTERM in integ-tests/dev-server.test.ts with a
process-group-aware terminator that: signals the whole group via -pid,
waits on the child's exit event, and SIGKILLs the group after a 5s
timeout if the process hangs. Spawn now uses detached:true so the
process-group signal actually reaches subprocesses of the dev server.
