test(server): stabilize daemon and Git fixture timing

[rynfar]

Two unrelated timing hazards were exposed by catch-up CI. The Prime daemon post-kill receipt test gave private-socket cleanup only 5 ms before it could reach the intended assertion. The PR-template fixture allowed Git automatic maintenance to write object packs while its scoped temporary repository was being removed.

Give the Prime test 250 ms for socket cleanup while still bounding the hung receipt, and disable auto-GC inside the PR-template test repository. Production daemon behavior and application Git settings are unchanged. The dedicated socket-cleanup timeout test remains at 5 ms.

Validation: 49 focused tests across both suites passed; server typecheck passed. The original failures are in #852 Test Server 2 and this PR's first Test Server 3 run. Fresh exact-head CI is running.
