feat: add bedrock-agent, bedrock-agentcore, bedrock-agentcore-control and eks clients (#222)

* feat: add bedrock-agent client

Generate @effect-aws/client-bedrock-agent from the AWS Smithy manifest.

Pin AWS SDK clients to 3.1045.0 and unify @smithy/types to 4.15.0 via pnpm
overrides: AWS SDK 3.1046+ ships runtimeConfig as non-configurable ESM, which
breaks the spy-based client tests.

* feat: add bedrock-agentcore client

Generate @effect-aws/client-bedrock-agentcore from the AWS Smithy manifest,
pinned to AWS SDK 3.1045.0 via the existing pnpm override.

* feat: add bedrock-agentcore-control client

Generate @effect-aws/client-bedrock-agentcore-control, pinned to AWS SDK
3.1045.0. Generated from the v3.1045.0 model tag since the latest manifest
references dataset/harness operations not present in the pinned SDK.

* chore: dedupe pnpm-lock.yaml

* feat: add eks client

Generate @effect-aws/client-eks from the AWS Smithy manifest (v3.1045.0 tag,
matching the AWS SDK baseline the repo pins to).

* chore: upgrade to latest aws-sdk, fix changesets

* Revert "chore: upgrade to latest aws-sdk, fix changesets"

This reverts commit 9964e97.

* chore: update video embed to a clickable thumbnail in README
