zeekay 6994cf05aa kv, not redis: rename the package, the extras and the URL scheme

We do not use Redis. The client was a go-redis fork and still said so
everywhere: `package redis`, `redis.NewClient`, `redis://`, `extra/redisotel`.
Consumers wrote `redis.Client` against a Valkey-backed store called KV.

  package redis            -> package kv          (93 decls)
  redis.X                  -> kv.X                (2,794 call sites)
  "redis: …" errors        -> "kv: …"             (206)
  extra/redis{otel,cmd,prometheus,census} -> extra/kv{otel,cmd,prometheus,census}
  redis:// , rediss://     -> kv:// , kvs://      (ParseURL)
  Redis*/‌*Redis* idents    -> KV*/*KV*
  REDIS_VERSION, REDIS_ENDPOINTS_CONFIG_PATH -> KV_*

I previously argued this rename was unsafe because much of it was "wire
contract". That was wrong, and the categorisation shows why: RESP command names
are GET/SET/HSET — they never contain the word. Of 5,771 occurrences only two
kinds were server-visible at all: the ParseURL scheme (we choose what we pass;
our configs already use kv://) and the CLIENT SETINFO lib-name label, which the
server merely records. Nothing here changes a byte of protocol.

Two things deliberately keep the old spelling:
  RediSearch  — names a specific external module the FT.* commands map to.
  StoreDist   — contains the letters by accident (sto-reDis-t), not the word.

Breaking for consumers by design: every import site must move redis.X -> kv.X.
Minor bump, never a major — this module stays v9 forever.

Maintenance Notifications

Seamless KV connection handoffs during cluster maintenance operations without dropping connections.

⚠️ Important Note

Maintenance notifications are currently supported only in standalone KV clients. Cluster clients (ClusterClient, FailoverClient, etc.) do not yet support this functionality.

Quick Start

client := kv.NewClient(&kv.Options{
    Addr:     "localhost:6379",
    Protocol: 3, // RESP3 required
	MaintNotificationsConfig: &maintnotifications.Config{
        Mode: maintnotifications.ModeEnabled,
    },
})

Modes

ModeDisabled - Maintenance notifications disabled
ModeEnabled - Forcefully enabled (fails if server doesn't support)
ModeAuto - Auto-detect server support (default)

Configuration

&maintnotifications.Config{
    Mode:                       maintnotifications.ModeAuto,
    EndpointType:               maintnotifications.EndpointTypeAuto,
    RelaxedTimeout:             10 * time.Second,
    HandoffTimeout:             15 * time.Second,
    MaxHandoffRetries:          3,
    MaxWorkers:                 0,    // Auto-calculated
    HandoffQueueSize:           0,    // Auto-calculated
    PostHandoffRelaxedDuration: 0,    // 2 * RelaxedTimeout
}

Endpoint Types

EndpointTypeAuto - Auto-detect based on connection (default)
EndpointTypeInternalIP - Internal IP address
EndpointTypeInternalFQDN - Internal FQDN
EndpointTypeExternalIP - External IP address
EndpointTypeExternalFQDN - External FQDN
EndpointTypeNone - No endpoint (reconnect with current config)

Auto-Scaling

Workers: min(PoolSize/2, max(10, PoolSize/3)) when auto-calculated Queue: max(20×Workers, PoolSize) capped by MaxActiveConns+1 or 5×PoolSize

Examples:

Pool 100: 33 workers, 660 queue (capped at 500)
Pool 100 + MaxActiveConns 150: 33 workers, 151 queue

How It Works

KV sends push notifications about cluster maintenance operations
Client creates new connections to updated endpoints
Active operations transfer to new connections
Old connections close gracefully
