* First version of batching w/out signatures.
* First version of pod signatures.
* Integrate batching with signatures.
* Fix merge conflicts.
* Fixes from self-review.
* Test fixes.
* Fix a bug that limited batches to size 2
Also add some new high-level logging and
simplify the pod affinity signature.
* Re-enable batching on perf tests for now.
* fwk.NewStatus(fwk.Success)
* Review feedback.
* Review feedback.
* Comment fix.
* Two plugin specific unit tests.:
* Add cycle state to the sign call, apply to topo spread.
Also add unit tests for several plugi signature
calls.
* Review feedback.
* Switch to distinct stats for hint and store calls.
* Switch signature from string to []byte
* Revert cyclestate in signs. Update node affinity.
Node affinity now sorts all of the various
nested arrays in the structure. CycleState no
longer in signature; revert to signing fewer
cases for pod spread.
* hack/update-vendor.sh
* Disable signatures when extenders are configured.

The test started without waiting for the ResourceSlice informer to have
synced. As a result, the "CEL-runtime-error-for-one-of-three-nodes" test case
failed randomly with a very low flake rate (less than 1% in local runs) because
CEL expressions never got evaluated due to not having the slices (yet).
Other tests also were less reliable, but not known to fail.
Extend Fit and BalancedAllocation PreScore state with the the
allocated state, the list of ResourceSlices and the device class
mapping. Gather these once during PreScore and pass them through
the scoring path instead of re-fetching for every scoring call.
This should speed up scoring of DRA extended resources, lowering
scheduling overhead.

Support for DeviceTaintRules depends on a significant amount of
additional code:
- ResourceSlice tracker is a NOP without it.
- Additional informers and corresponding permissions in scheduler and controller.
- Controller code for handling status.
Not all users necessarily need DeviceTaintRules, so adding a second feature
gate for that code makes it possible to limit the blast radius of bugs in that
code without having to turn off device taints and tolerations entirely.
Add a new `bindingTimeout` field to DynamicResources plugin args and wire it
into PreBind.
Changes:
- API: add `bindingTimeout` to DynamicResourcesArgs (staging + internal types).
- Defaults: default to 600 seconds when BOTH DRADeviceBindingConditions and
DRAResourceClaimDeviceStatus are enabled.
- Validation: require >= 1s; forbid when either feature gate is disabled.
- Plugin: plumbs args into `pl.bindingTimeout` and uses it in
`wait.PollUntilContextTimeout` for binding-condition wait logic.
- Plugin: remove legacy `BindingTimeoutDefaultSeconds`.
Tests:
- Add/adjust unit tests for validation and PreBind timeout path.
- Ensure <1s and negative values are rejected; forbids when gates disabled.
