This commit introduces comprehensive LKE NodePool scale-up functionality with proper concurrency control and extensive test coverage.

Major Changes:
- Add LKE NodePool scale-up capability to support existing NodePool expansion
- Implement KeyedMutex utility for per-key synchronization to prevent race conditions
- Enhance LKE provider with cluster name tracking and operation timeouts
- Add comprehensive test suites for garbage collection and LKE operations

Remove the `v1` import alias for the `v1alpha1` package throughout the codebase. Use the full `v1alpha1` package name directly to avoid confusion with the Karpenter v1 API. Update all references in cloudprovider, controllers, drift detection, and utility packages. Also fix incorrect finalizer constant reference from `v1.TerminationFinalizer` to `karpv1.TerminationFinalizer` in nodeclass controller.

Add explicit `ErrNodesProvisioning` error to handle nodes with zero InstanceID in standard tier. Check all nodes before returning error to prioritize finding claimable instances. Add 500ms sleep and retry when nodes are still provisioning. Remove redundant type declaration in fake client.

Extract LKE pool lookup into `findLKENodePoolFromLinodeInstanceID` helper to reduce duplication in Delete method. Remove redundant instance fetching, tag parsing, and pool mutex locking from Delete - all now handled by the helper. Use `findNodeInPool` helper for node lookup instead of inline loop. Update simple example to add 30s consolidation period. Reduce default Karpenter replicas from 2 to 1 in chart values.

…tag in LKE mode

Replace custom `lke-pool-id` tag with Linode's automatic `nodepool=<id>` tag for pool identification in enterprise tier. Use `LKEClusterID` field on instances for cluster association instead of tags. Update instance listing to filter by cluster ID field. Simplify pool resolution logic by using native Linode tags. Update fake client to set `LKEClusterID` on created instances. Remove pool ID tag from instance claim flow.

Fixed major issues with LKE enterprise creation flow (no more duplicate nodes being created due to API timing). Also fixed List() behaviour that was throwing a lot of errors.

…helper extraction. Reduced the linter complexity.

Extract instance type resolution, existing instance lookup, and pool locking into separate helper methods. Introduce explicit error types (ErrNoClaimableInstance, ErrClaimFailed, ErrPoolScaleFailed) to distinguish retry-able conditions from fatal errors. Replace inline pool mutex lock/unlock with withPoolLock helper for cleaner resource management. Simplify attemptCreate by removing nodeID return value and using instance

Add ProviderConfig struct to LKE provider with CreateDeadline, TagVerificationTimeout, and RetryDelay fields. Add corresponding CLI flags and environment variables (LKE_CREATE_DEADLINE, LKE_TAG_VERIFICATION_TIMEOUT, LKE_RETRY_DELAY) with defaults matching previous hardcoded values (10s, 4s, 2s). Thread config through operator initialization and test setup. Extract retry error check into isRetryableCreateError helper. Replace hardcoded sleep

Add lkeCreateDeadline, lkeTagVerificationTimeout, and lkeRetryDelay settings to chart values with defaults (10s, 4s, 2s). Wire settings through deployment template as LKE_CREATE_DEADLINE, LKE_TAG_VERIFICATION_TIMEOUT, and LKE_RETRY_DELAY environment variables. Add documentation comments for each timeout parameter.
