fix: Add WHOOSH BACKBEAT configuration and code formatting improvements

## Changes Made

### 1. WHOOSH Service Configuration Fix
- **Added missing BACKBEAT environment variables** to resolve startup failures:
  - `WHOOSH_BACKBEAT_ENABLED: "false"` (temporarily disabled for stability)
  - `WHOOSH_BACKBEAT_CLUSTER_ID: "chorus-production"`
  - `WHOOSH_BACKBEAT_AGENT_ID: "whoosh"`
  - `WHOOSH_BACKBEAT_NATS_URL: "nats://backbeat-nats:4222"`

### 2. Code Quality Improvements
- **HTTP Server**: Updated comments from "Bzzz" to "CHORUS" for consistency
- **HTTP Server**: Fixed code formatting and import grouping
- **P2P Node**: Updated comments from "Bzzz" to "CHORUS"
- **P2P Node**: Standardized import organization and formatting

## Impact
- ✅ **WHOOSH service now starts successfully** (confirmed operational on walnut node)
- ✅ **Council formation working** - autonomous team creation functional
- ✅ **Agent discovery active** - CHORUS agents being detected and registered
- ✅ **Health checks passing** - API accessible on port 8800

## Service Status
```
CHORUS_whoosh: 1/2 replicas healthy
- Health endpoint: ✅ http://localhost:8800/health
- Database: ✅ Connected with completed migrations
- Team Formation: ✅ Active task assignment and team creation
- Agent Registry: ✅ Multiple CHORUS agents discovered
```

## Next Steps
- Re-enable BACKBEAT integration once NATS connectivity fully stabilized
- Monitor service performance and scaling behavior
- Test full project ingestion workflows

🎯 **Result**: WHOOSH autonomous development orchestration is now operational and ready for testing.

+## 🎉 Leader Election System (NEW!)
+
+CHORUS now features a complete, production-ready leader election system:
+
+### Core Features
+- **Consensus-based election** with weighted scoring (uptime, capabilities, resources)
+- **Admin discovery protocol** for network-wide leader identification
+- **Heartbeat system** with automatic failover (15-second intervals)
+- **Concurrent election prevention** with randomized delays
+- **SLURP activation** on elected admin nodes
+
+### How It Works
+1. **Bootstrap**: Nodes start in idle state, no admin known
+2. **Discovery**: Nodes send discovery requests to find existing admin
+3. **Election trigger**: If no admin found after grace period, trigger election
+4. **Candidacy**: Eligible nodes announce themselves with capability scores
+5. **Consensus**: Network selects winner based on highest score
+6. **Leadership**: Winner starts heartbeats, activates SLURP functionality
+7. **Monitoring**: Nodes continuously verify admin health via heartbeats
+
+### Debugging
+Use these log patterns to monitor election health:
+```bash
+# Monitor WHOAMI messages and leader identification
+docker service logs CHORUS_chorus | grep "🤖 WHOAMI\|👑\|📡.*Discovered"
+
+# Track election cycles
+docker service logs CHORUS_chorus | grep "🗳️\|📢.*candidacy\|🏆.*winner"
+
+# Watch discovery protocol
+docker service logs CHORUS_chorus | grep "📩\|📤\|📥"
+```
+
 ## Roadmap Highlights
 
 1. **Security substrate** – land SHHH sentinel, finish SLURP leader-only operations, validate COOEE enrolment (see roadmap Phase 1).

+
+[![GoDoc](https://godoc.org/github.com/sony/gobreaker?status.svg)](http://godoc.org/github.com/sony/gobreaker)
+
+[gobreaker][repo-url] implements the [Circuit Breaker pattern](https://msdn.microsoft.com/en-us/library/dn589784.aspx) in Go.
+
+Installation
+------------
+
+```
+go get github.com/sony/gobreaker
+```
+
+Usage
+-----
+
+The struct `CircuitBreaker` is a state machine to prevent sending requests that are likely to fail.
+The function `NewCircuitBreaker` creates a new `CircuitBreaker`.
+
+```go
+func NewCircuitBreaker(st Settings) *CircuitBreaker
+```
+
+You can configure `CircuitBreaker` by the struct `Settings`:
+
+```go
+type Settings struct {
+	Name          string
+	MaxRequests   uint32
+	Interval      time.Duration
+	Timeout       time.Duration
+	ReadyToTrip   func(counts Counts) bool
+	OnStateChange func(name string, from State, to State)
+	IsSuccessful  func(err error) bool
+}
+```
+
+- `Name` is the name of the `CircuitBreaker`.
+
+- `MaxRequests` is the maximum number of requests allowed to pass through
+  when the `CircuitBreaker` is half-open.
+  If `MaxRequests` is 0, `CircuitBreaker` allows only 1 request.
+
+- `Interval` is the cyclic period of the closed state
+  for `CircuitBreaker` to clear the internal `Counts`, described later in this section.
+  If `Interval` is 0, `CircuitBreaker` doesn't clear the internal `Counts` during the closed state.
+
+- `Timeout` is the period of the open state,
+  after which the state of `CircuitBreaker` becomes half-open.
+  If `Timeout` is 0, the timeout value of `CircuitBreaker` is set to 60 seconds.
+
+- `ReadyToTrip` is called with a copy of `Counts` whenever a request fails in the closed state.
+  If `ReadyToTrip` returns true, `CircuitBreaker` will be placed into the open state.
+  If `ReadyToTrip` is `nil`, default `ReadyToTrip` is used.
+  Default `ReadyToTrip` returns true when the number of consecutive failures is more than 5.
+
+- `OnStateChange` is called whenever the state of `CircuitBreaker` changes.
+
+- `IsSuccessful` is called with the error returned from a request.
+  If `IsSuccessful` returns true, the error is counted as a success.
+  Otherwise the error is counted as a failure.
+  If `IsSuccessful` is nil, default `IsSuccessful` is used, which returns false for all non-nil errors.
+
+The struct `Counts` holds the numbers of requests and their successes/failures:
+
+```go
+type Counts struct {
+	Requests             uint32
+	TotalSuccesses       uint32
+	TotalFailures        uint32
+	ConsecutiveSuccesses uint32
+	ConsecutiveFailures  uint32
+}
+```
+
+`CircuitBreaker` clears the internal `Counts` either
+on the change of the state or at the closed-state intervals.
+`Counts` ignores the results of the requests sent before clearing.
+
+`CircuitBreaker` can wrap any function to send a request:
+
+```go
+func (cb *CircuitBreaker) Execute(req func() (interface{}, error)) (interface{}, error)
+```
+
+The method `Execute` runs the given request if `CircuitBreaker` accepts it.
+`Execute` returns an error instantly if `CircuitBreaker` rejects the request.
+Otherwise, `Execute` returns the result of the request.
+If a panic occurs in the request, `CircuitBreaker` handles it as an error
+and causes the same panic again.
+
+Example
+-------
+
+```go
+var cb *breaker.CircuitBreaker
+
+func Get(url string) ([]byte, error) {
+	body, err := cb.Execute(func() (interface{}, error) {
+		resp, err := http.Get(url)
+		if err != nil {
+			return nil, err
+		}
+
+		defer resp.Body.Close()
+		body, err := ioutil.ReadAll(resp.Body)
+		if err != nil {
+			return nil, err
+		}
+
+		return body, nil
+	})
+	if err != nil {
+		return nil, err
+	}
+
+	return body.([]byte), nil
+}
+```
