Solution for the agressive polling:
- no WNS (although we could add it later as another avenue for
notifications)
- fleetd advertises a sync capability, persisted as
`mdm_windows_enrollments.fleetd_sync_capable`
- The management session relaxes the DMClient poll
(`poll_schedule_relaxed`)
- When an MDM command is queued, `has_pending_commands` flips, the next
orbit check-in returns `WindowsMDMSyncRequest`, and fleetd runs
`deviceenroller` to deliver it immediately
- older fleetd versions keep the 1-minute poll

Changes to osquery_perf and any additional changes after loadtesting
will be done in a separate PR.
# Checklist for submitter
If some of the following don't apply, delete the relevant line.
- [x] Changes file added for user-visible changes in `changes/`,
`orbit/changes/` or `ee/fleetd-chrome/changes`.
See [Changes
files](https://github.com/fleetdm/fleet/blob/main/docs/Contributing/guides/committing-changes.md#changes-files)
for more information.
- [x] Timeouts are implemented and retries are limited to avoid infinite
loops
## Testing
- [x] Added/updated automated tests
- [x] Where appropriate, [automated tests simulate multiple hosts and
test for host
isolation](https://github.com/fleetdm/fleet/blob/main/docs/Contributing/reference/patterns-backend.md#unit-testing)
(updates to one hosts's records do not affect another)
- [x] QA'd all new/changed functionality manually
## Database migrations
- [x] Checked schema for all modified table for columns that will
auto-update timestamps during migration.
- [x] Confirmed that updating the timestamps is acceptable, and will not
cause unwanted side effects.
- [x] Ensured the correct collation is explicitly set for character
columns (`COLLATE utf8mb4_unicode_ci`).
## fleetd/orbit/Fleet Desktop
- [x] Verified compatibility with the latest released version of Fleet
(see [Must
rule](https://github.com/fleetdm/fleet/blob/main/docs/Contributing/workflows/fleetd-development-and-release-strategy.md))
- [x] If the change applies to only one platform, confirmed that
`runtime.GOOS` is used as needed to isolate changes
- [x] Verified that fleetd runs on macOS, Linux and Windows
- [x] Verified auto-update works from the released version of component
to the new version (see [tools/tuf/test](../tools/tuf/test/README.md))

## Summary by CodeRabbit
* **New Features**
* On-demand Windows MDM sync: servers can request immediate delivery of
queued MDM commands to Windows clients; Orbit triggers client-side sync
on Windows.
* **Enhancements**
* Orbit throttles per-device on-demand sync to avoid excessive runs.
* Server reconciles and persists device poll schedule (fast vs relaxed)
and exposes consolidated host MDM state (awaiting-configuration +
has-pending-commands).
* **Tests**
* Added tests covering host config state, pending-command flows,
poll-schedule toggling, and on-demand sync behavior.
