What this does

Second stage of the staged rollout for the periodic workspace-handoff checkpoint coordinator (previously enabled for dogfood only in #15026, after #14589, #14573, #14588). Moves FeatureFlag::PeriodicHandoffCheckpoints from DOGFOOD_FLAGS to PREVIEW_FLAGS so the coordinator bakes on preview/canary builds before promoting to RELEASE_FLAGS (or enabling it by default) for stable.

Dogfood coverage is preserved: PREVIEW_FLAGS is automatically included in dogfood builds, so removing the flag from DOGFOOD_FLAGS is a no-op for dogfood.

OzHandoff (the other prerequisite flag) remains enabled by default for all builds via the oz_handoff Cargo default feature, so no additional change is needed there.

Testing

  • cargo check -p warp_features, cargo clippy -p warp_features --all-targets --all-features -- -D warnings, cargo test -p warp_features, and cargo fmt --check -p warp_features all pass.
  • No UI-testable behavior; this only changes which build channel the flag is active on.

CHANGELOG-NONE

Second stage of the staged rollout for the periodic workspace-handoff
checkpoint coordinator. Moves FeatureFlag::PeriodicHandoffCheckpoints
from DOGFOOD_FLAGS to PREVIEW_FLAGS so the coordinator is exercised on
preview/canary builds (which also covers dogfood, since PREVIEW_FLAGS
is automatically included there) ahead of a stable rollout via
RELEASE_FLAGS.

Overview

This PR promotes FeatureFlag::PeriodicHandoffCheckpoints from dogfood-only to preview by removing it from DOGFOOD_FLAGS, adding it to PREVIEW_FLAGS, and updating the flag documentation to describe the new rollout state. The existing dev/dogfood channel setup also includes PREVIEW_FLAGS, so dogfood coverage is preserved.
