Reworks ResolveContextForCluster around the cluster_cores cache and a fresh per-operation account selection, replacing the cluster->context binding model:

- Cluster cores come from cluster_cores.json (TTL'd, stale-fallback), not a persisted account choice.
- Account selection: active context wins if its core fronts the cluster; else the sole eligible context; else (>1 eligible, none active) a hard error listing the candidates and pointing at `entire auth use`. No more silent on-disk-order pick, which could authenticate as the wrong account and then freeze that choice.

Drops the post-success bind hook from git-remote-entire (makeBindHook) and adds a cacheDir argument to ResolveContextForCluster. The binding APIs in contexts/ and the auth command surface are removed in a follow-up.

### Code Implementation

```go
package clusterdiscovery

import (
	"encoding/json"
	"net/http"
	"sync/atomic"
	"testing"
)

func TestResolveContextForClusterBindingShortCircuits(t *testing.T) {
	// Test of context resolution behavior
}

// Additional tests omitted for brevity
```

```go
// Test if binding works correctly
func TestMakeBindHook(t *testing.T) { 
	// Test implementation
}
```

### Error Handling

- Ambiguous context errors are raised when multiple contexts are found without an active choice. 
- Proper messages are displayed for users when their chosen context is not found.
