## Summary by CodeRabbit
* **New Features**
* Enhanced GitOps exception handling for labels, secrets, and software
with clearer enforcement and omission semantics.
* Server-side prefetch of team software so omitted team software can
preserve existing installers during validation.
* Presence flags track whether top-level keys (labels, secrets,
software) were provided versus omitted.
* **Behavior Changes**
* Omitted vs empty sections are now distinguished: omission can mean
“no-op” or “delete-all” depending on exception settings.
* GitOps YAML can define and manage labels directly; validations now
reject YAML that includes keys marked as excepted.

For unreleased bug fixes in a release candidate, one of:
- [X] Confirmed that the fix is not expected to adversely impact load
test results
I don't think so. There is a bit of overhead when this feature is used
since we have to fetch software from the server, but it would be done in
a specific test, so even if there is an impact it should affect existing
load testing, only new, specific tests.
For #31055.
- [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] Input data is properly validated, `SELECT *` is avoided, SQL
injection is prevented (using placeholders for values in statements)
## Testing
- [X] Added/updated automated tests
- [x] QA'd all new/changed functionality manually
