Hive-Mind Resume Function Not Working - Multiple Async/Await Issue

## Description
The `claude-flow hive-mind resume` command is broken due to multiple async/await inconsistencies and incomplete in-memory mode support in the session manager. Users experience errors like `sessions.forEach is not a function` and failed session resumption.

## Environment
- **OS**: Linux/Windows/macOS (affects all platforms)
- **Node.js**: All versions
- **Package**: claude-code-flow v2.0.0-alpha.70

## Steps to Reproduce
1. Run `npx claude-flow hive-mind spawn "test session"`
2. Pause the session with Ctrl+C
3. Run `npx claude-flow hive-mind sessions` → Error: `sessions.forEach is not a function`
4. Run `npx claude-flow hive-mind resume ` → Session not found or silent failure

## Expected Behavior
- Sessions should list correctly showing paused sessions
- Resume command should successfully restore paused sessions
- Both SQLite and in-memory modes should work

## Actual Behavior
- `sessions` command fails with `forEach is not a function`
- Resume command fails silently or with "Session not found" errors
- In-memory mode sessions cannot be resumed (only database operations implemented)

## Root Cause Analysis

### 🔴 **Critical Issue 1**: Missing `await` in `resumeSession()`
**File**: `src/cli/simple-commands/hive-mind/session-manager.js`
```javascript
// BROKEN - Line ~331
async resumeSession(sessionId) {
const session = this.getSession(sessionId); // ❌ Missing await\!
// Should be: const session = await this.getSession(sessionId);
```

### 🔴 **Critical Issue 2**: Missing `await` in `showSessions()`
**File**: `src/cli/simple-commands/hive-mind.js` (Line ~2423)
```javascript
// BROKEN - User already identified this
const sessions = sessionManager.getActiveSessions(); // ❌ Missing await\!
// Should be: const sessions = await sessionManager.getActiveSessions();
```

### 🔴 **Critical Issue 3**: `resumeSession()` Missing In-Memory Mode Support
The `resumeSession()` method only contains SQLite database operations but no in-memory mode handling. When SQLite is unavailable, the system defaults to in-memory mode, but resume operations fail because they try to execute database queries on in-memory sessions.

### 🔴 **Critical Issue 4**: Missing `await` in `getActiveSessionsWithProcessInfo()`
```javascript
// BROKEN
getActiveSessionsWithProcessInfo() {
const sessions = this.getActiveSessions(); // ❌ Missing await
}
// Should be async method with await
```

## Proposed Solution

### Fix 1: Add Missing `await` Keywords
```javascript
// In session-manager.js
async resumeSession(sessionId) {
const session = await this.getSession(sessionId); // ✅ Add await
// ... rest of method
}

// In hive-mind.js
async function showSessions(flags) {
const sessions = await sessionManager.getActiveSessions(); // ✅ Add await
// ... rest of method
}

// Fix getActiveSessionsWithProcessInfo
async getActiveSessionsWithProcessInfo() {
const sessions = await this.getActiveSessions(); // ✅ Add await and async
// ... rest of method
}
```

### Fix 2: Add In-Memory Mode Support to `resumeSession()`
```javascript
async resumeSession(sessionId) {
const session = await this.getSession(sessionId);
if (\!session) {
throw new Error(`Session ${sessionId} not found`);
}

console.log(`Resuming session ${sessionId} from status: ${session.status}`);

if (this.isInMemory) {
// ✅ ADD IN-MEMORY MODE HANDLING
const sessionData = this.memoryStore.sessions.get(sessionId);
if (sessionData) {
sessionData.status = 'active';
sessionData.resumed_at = new Date().toISOString();
sessionData.updated_at = new Date().toISOString();
}

await this.logSessionEvent(sessionId, 'info', 'Session resumed', null, {
pausedDuration: session.paused_at ? new Date() - new Date(session.paused_at) : null,
});

return session;
} else {
// EXISTING DATABASE CODE (keep as-is)
const stmt = this.db.prepare(`
UPDATE sessions
SET status = 'active', resumed_at = CURRENT_TIMESTAMP, updated_at = CURRENT_TIMESTAMP
WHERE id = ?
`);
stmt.run(sessionId);
// ... rest of existing database code
}
}
```

## Files That Need Changes
- `src/cli/simple-commands/hive-mind/session-manager.js`
- `src/cli/simple-commands/hive-mind.js`
- Any other files calling `getActiveSessionsWithProcessInfo()` without await

## Testing Checklist
- [ ] `hive-mind sessions` lists sessions without errors
- [ ] `hive-mind resume ` works with SQLite database
- [ ] `hive-mind resume ` works with in-memory mode
- [ ] Resume properly restores session state
- [ ] Error handling for invalid session IDs
- [ ] Both interactive and direct session ID resume work

## Impact
- **Severity**: High - Core functionality completely broken
- **Users Affected**: All users trying to use hive-mind resume functionality
- **Workaround**: None currently available

## Additional Context
This appears to be a refactoring issue where methods were converted to async but not all callers were updated to use `await`. The in-memory fallback mode was also not fully implemented for resume operations.

**Reporter**: Analysis conducted via deep code investigation
**Priority**: P1 - Critical functionality broken

Start with src/cli/simple-commands/hive-mind/session-manager.js and src/cli/simple-commands/hive-mind.js, then reproduce the issue with the listed hive-mind spawn, sessions, and resume commands. Check the async callers and in-memory and SQLite paths; done means sessions list successfully and resume restores valid sessions in both modes, including invalid IDs.
