It collects replication-group, cache-cluster, and serverless-cache endpoints across configured regions and clients, with optional metadata and handling for partial listing failures.

Review comments at @pkg/providers/aws/elasticache.go:
- Line 85: Update appendEndpoint to mark replication-group and cache-cluster
node endpoints as private, and derive serverless endpoint Public status from the
API’s ConnectionType, treating vpc as private and public as public. Since the
current AWS SDK does not expose ConnectionType, use an available API response
source or SDK support rather than assuming serverless endpoints are public.
- Line 53: Pass the `ctx` received by `GetResource` into
`listElastiCacheResources` and update that helper to accept the context. Use the
context-aware pagination methods for replication groups, cache clusters, and
serverless caches so cancellation stops active and subsequent requests; update
all three test callers to pass `context.Background()`.
- Around line 108-110: Update the error return in DescribeReplicationGroupsPages
handling to return the accumulated list alongside the wrapped error instead of
nil, preserving endpoints collected from earlier pages for GetResource to merge.

Pass ctx to the AWS pagination calls.
GetResource receives ctx, but each worker calls listElastiCacheResources without it and then waits in wg.Wait(). The helper uses non-context pagination methods, so cancellation cannot stop an active request or prevent later listing calls in that worker.
Use the context-aware methods and update the test callers.

official AWS documentation ElastiCache endpoints VPC private IP public access serverless cache
💡 Result:
**Official AWS documentation:**
- **Cache connection endpoints:** Your application connects using the cache’s endpoint—not the ElastiCache management API endpoint. AWS explains which endpoint to use for node-based Valkey/Redis OSS clusters and how to find a Serverless cache’s endpoint and port. ([docs.aws.amazon.com](https://docs.aws.amazon.com/AmazonElastiCache/latest/dg/Endpoints.html?utm_source=openai))
- **VPC access / private IPs:** Node-based clusters and Serverless caches using a VPC endpoint are accessed from within AWS/VPC networking. AWS says VPC-hosted ElastiCache resources have no public IP address; access from other networks can use supported private connectivity such as peering, VPN, or Direct Connect. ([docs.aws.amazon.com](https://docs.aws.amazon.com/AmazonElastiCache/latest/dg/accessing-elasticache.html?utm_source=openai))
- **Public access:** AWS documents public endpoints for **ElastiCache Serverless with Valkey 9.0 or later**. These connect over the internet without a VPC and require IAM authentication and TLS 1.3. ([docs.aws.amazon.com](https://docs.aws.amazon.com/AmazonElastiCache/latest/dg/serverless-public-endpoints-chapter.html?utm_source=openai))
- **Important distinction:** AWS PrivateLink interface endpoints are for calling the **ElastiCache API** privately; they are not the cache’s data-connection endpoint. ([docs.aws.amazon.com](https://docs.aws.amazon.com/AmazonElastiCache/latest/dg/elasticache-privatelink.html?utm_source=openai))

AWS SDK for Go v1.55.5 ElastiCache ServerlessCache fields Endpoint ReaderEndpoint NetworkType public endpoint
💡 Result:
In **AWS SDK for Go v1.55.5**, `elasticache.ServerlessCache` has `Endpoint` and `ReaderEndpoint` fields (both `*Endpoint`), but **does not have `NetworkType` or `ConnectionType` fields**. `NetworkType` exists on other ElastiCache structs in this version, not on `ServerlessCache`. ([raw.githubusercontent.com](https://raw.githubusercontent.com/aws/aws-sdk-go/v1.55.5/service/elasticache/api.go))
The current ElastiCache API describes `ConnectionType` (`vpc` or `public`) and `NetworkType` (`ipv4`, `ipv6`, or `dual_stack`) for serverless caches, but those fields are absent from the v1.55.5 Go struct. That API documentation reflects the current service, not necessarily the API model bundled with v1.55.5. ([docs.aws.amazon.com](https://docs.aws.amazon.com/AmazonElastiCache/latest/APIReference/API_ServerlessCache.html))
**Public endpoint:** the SDK struct’s `Endpoint` is the cache connection endpoint; it does not expose a separate “public endpoint” field. The current API has a `ConnectionType` setting for public vs. VPC access, but v1.55.5’s `ServerlessCache` type cannot represent that setting directly. ([raw.githubusercontent.com](https://raw.githubusercontent.com/aws/aws-sdk-go/v1.55.5/service/elasticache/api.go))

Classify ElastiCache endpoints by connection type.
appendEndpoint marks replication-group, cache-cluster, and serverless-cache endpoints as Public: true. VPC ElastiCache endpoints are private, so this can label private cache resources as internet-facing.
Mark node-based endpoints as private. For serverless caches, set Public from the API’s ConnectionType (vpc or public). aws-sdk-go v1.55.5 does not expose that field, so do not assume that every serverless endpoint is public.
The RDS implementation is not an aligned precedent because it also sets Public: true and records publicly_accessible separately.

Fixes #765
New
elasticacheservice: replication group, cluster node and serverless cache endpoints. Bumps aws-sdk-go to v1.55.5 for the serverless API (v1.55.8 marks the SDK deprecated and fails lint).Tested against a fake API server with the real SDK client; no live account.
