v0.2: Implement guarded manual reconnect with Ctrl+K

[Mewt0]

Goal

Implement the first real connection-changing path, but only when the user explicitly presses Ctrl+K.

Preconditions

• Issue v0.1: Validate diagnostic detector on exact WoT client #2 completed and diagnostic detector validated on the exact client.

Scope

• Resolve IGameplayLogic through the dependency system.
• Add a single-flight guard so duplicate requests are ignored.
• Validate not replay / valid client state before disconnect.
• Call the stock goToLoginByDisconnectRQ() path.
• Log request, guard decisions, disconnect start and resulting state transition.
• Keep automatic RED-triggered reconnect disabled.

Client APIs to verify

• skeletons.gameplay.IGameplayLogic
• gameplay.delegator.GameplayLogic.goToLoginByDisconnectRQ()
• skeletons.connection_mgr.IConnectionManager
• BattleReplay.isPlaying()

Acceptance criteria

• Ctrl+K causes one controlled stock disconnect request.
• Repeated Ctrl+K while reconnect is in progress does not produce duplicate disconnects.
• Replay remains inert.
• No external socket manipulation, process restart or executable patching.
• Automatic lag detector still only logs and never disconnects.

Tests

• Ctrl+K in battle with healthy connection.
• Ctrl+K during sustained RED.
• Repeated Ctrl+K presses.
• Ctrl+K in replay.
• Normal battle exit while controller is idle/busy.
