제목 'refactor: 미구독 STOMP 세션 정리'는 이 PR의 핵심 변경인 미구독 STOMP 세션의 구독 제한시간 예약, 만료 시 정리, 구독 완료 시 예약 취소를 잘 나타냅니다. 다만 제목에 구독 제한시간 도입이라는 기능 추가 성격이 드러나지 않고 'refactor'로 표시되어 있습니다. 또한 AGENTS.md 문서 지침 일원화 변경도 포함되지만 제목에서는 다루지 않아도 되는 부수적 변경입니다.

Explanation
설명은 작업 내용, 검증 명령, 이슈 연결(Closes #855)을 포함하고 있어 템플릿의 주요 섹션을 대부분 충족합니다. 그러나 '특이 사항'과 '리뷰 요구사항(선택)' 섹션은 템플릿 안내 문구만 남아 있고 작성되지 않았습니다. 템플릿의 '관련 이슈' 항목은 'resolves: #이슈 번호' 형식인데 본문은 'Closes #855'로 작성되어 있습니다. 두 항목 모두 기능상 문제는 없으나 형식이 템플릿과 다릅니다. 핵심 내용은 충분히 기술되어 있으므로 전체적으로는 대체로 완성된 설명입니다.
Resolution
필수 항목은 아니지만 '특이 사항'에 AGENTS.md 지침 변경(CLAUDE.md 및 AGENTS.local.md 참조)과 구독 제한시간 설정값(websocket.subscription-timeout)에 대한 내용을 적고, '리뷰 요구사항'에 경쟁 조건 처리(예약 토큰 비교)와 WebSocketSessionDecoratorFactory의 세션 정리 흐름을 중점 검토 항목으로 적어 주세요. 관련 이슈 항목은 템플릿 형식인 'resolves: #855'로 맞추는 것을 권장합니다.

* ## Constructor Details
* ### WebSocketTransportRegistration
public WebSocketTransportRegistration()
* ## Method Details
* ### setMessageSizeLimit
public WebSocketTransportRegistration setMessageSizeLimit(int messageSizeLimit)
Configure the maximum size of an inbound sub-protocol message, such as a STOMP frame which may be aggregated from multiple WebSocket messages.
The default value is 64K (i.e. 64 * 1024).
Note: This is not the same as the size of an individual WebSocket message which needs to be configured at the WebSocket server level instead. See the reference documentation for details.
* ### getMessageSizeLimit
@Nullable protected Integer getMessageSizeLimit()
Protected accessor for internal use.
* ### setSendTimeLimit
public WebSocketTransportRegistration setSendTimeLimit(int timeLimit)
Configure a time limit (in milliseconds) for the maximum amount of a time allowed when sending messages to a WebSocket session or writing to an HTTP response when SockJS fallback option are in use.
In general WebSocket servers expect that messages to a single WebSocket session are sent from a single thread at a time. This is automatically guaranteed when using `@EnableWebSocketMessageBroker` configuration. If message sending is slow, or at least slower than rate of messages sending, subsequent messages are buffered until either the `sendTimeLimit` or the `sendBufferSizeLimit` are reached at which point the session state is cleared and an attempt is made to close the session.
NOTE that the session time limit is checked only on attempts to send additional messages. So if only a single message is sent and it hangs, the session will not time out until another message is sent or the underlying physical socket times out. So this is not a replacement for WebSocket server or HTTP connection timeout but is rather intended to control the extent of buffering of unsent messages.
NOTE that closing the session may not succeed in actually closing the physical socket and may also hang. This is true especially when using blocking IO such as the BIO connector in Tomcat that is used by default on Tomcat 7. Therefore, it is recommended to ensure the server is using non-blocking IO such as Tomcat's NIO connector that is used by default on Tomcat 8. If you must use blocking IO consider customizing OS-level TCP settings, for example `/proc/sys/net/ipv4/tcp_retries2` on Linux.
The default value is 10 seconds (i.e. 10 * 1000).
Parameters:
`timeLimit` - the timeout value in milliseconds; the value must be greater than 0, otherwise it is ignored.
* ### getSendTimeLimit
@Nullable protected Integer getSendTimeLimit()
Protected accessor for internal use.
* ### setSendBufferSizeLimit
public WebSocketTransportRegistration setSendBufferSizeLimit(int sendBufferSizeLimit)
Configure the maximum amount of data to buffer when sending messages to a WebSocket session, or an HTTP response when SockJS fallback option are in use.
In general WebSocket servers expect that messages to a single WebSocket session are sent from a single thread at a time. This is automatically guaranteed when using `@EnableWebSocketMessageBroker` configuration. If message sending is slow, or at least slower than rate of messages sending, subsequent messages are buffered until either the `sendTimeLimit` or the `sendBufferSizeLimit` are reached at which point the session state is cleared and an attempt is made to close the session.

If you must use blocking IO consider customizing OS-level TCP settings, for example `/proc/sys/net/ipv4/tcp_retries2` on Linux.
The default value is 512K (i.e. 512 * 1024).
Parameters:
`sendBufferSizeLimit` - the maximum number of bytes to buffer when sending messages; if the value is less than or equal to 0 then buffering is effectively disabled.
* ### getSendBufferSizeLimit
@Nullable protected Integer getSendBufferSizeLimit()
Protected accessor for internal use.
* ### setTimeToFirstMessage
public WebSocketTransportRegistration setTimeToFirstMessage(int timeToFirstMessage)
Set the maximum time allowed in milliseconds after the WebSocket connection is established and before the first sub-protocol message is received.
This handler is for WebSocket connections that use a sub-protocol. Therefore, we expect the client to send at least one sub-protocol message in the beginning, or else we assume the connection isn't doing well, for example, proxy issue, slow network, and can be closed.
By default this is set to `60,000` (1 minute).
Parameters:
`timeToFirstMessage` - the maximum time allowed in milliseconds
Since:
5.1
* ### getTimeToFirstMessage
@Nullable protected Integer getTimeToFirstMessage()
Protected accessor for internal use.
* ### setDecoratorFactories
public WebSocketTransportRegistration setDecoratorFactories(WebSocketHandlerDecoratorFactory... factories)
Configure one or more factories to decorate the handler used to process WebSocket messages. This may be useful in some advanced use cases, for example to allow Spring Security to forcibly close the WebSocket session when the corresponding HTTP session expires.
Since:
4.1.2
* ### addDecoratorFactory
public WebSocketTransportRegistration addDecoratorFactory(WebSocketHandlerDecoratorFactory factory)
Add a factory that to decorate the handler used to process WebSocket messages. This may be useful for some advanced use cases, for example to allow Spring Security to forcibly close the WebSocket session when the corresponding HTTP session expires.

public class ConcurrentWebSocketSessionDecorator extends WebSocketSessionDecorator
Wrap a `WebSocketSession` to guarantee only one thread can send messages at a time.
If a `send` is slow, subsequent attempts to send more messages from other threads will not be able to acquire the flush lock, and messages will be buffered instead. At that time, the specified buffer-size limit and send-time limit will be checked, and the session will be closed if the limits are exceeded.

If this flag is set to `true` and the underlying WebSocket server supports partial messages, then a large WebSocket message, or one of an unknown size may be split and maybe received over multiple calls to `WebSocketHandler.handleMessage(WebSocketSession, WebSocketMessage)`. The flag `WebSocketMessage.isLast()` indicates if the message is partial and whether it is the last part.
Specified by:
`supportsPartialMessages` in interface `WebSocketHandler`
* ### decorateSession
protected WebSocketSession decorateSession(WebSocketSession session)
Decorate the given `WebSocketSession`, if desired.
The default implementation builds a `ConcurrentWebSocketSessionDecorator` with the configured `send-time limit` and `buffer-size limit`.
Parameters:
`session` - the original `WebSocketSession`
Returns:
the decorated `WebSocketSession`, or potentially the given session as-is
Since:
4.3.13
* ### findProtocolHandler
protected final SubProtocolHandler findProtocolHandler(WebSocketSession session)
Find a `SubProtocolHandler` for the given session.
Parameters:
`session` - the `WebSocketSession` to find a handler for
* ### toString
public String toString()
Overrides:
`toString` in class `Object`</excerpt>

1. WebSocketSession.close()를 단일 제한시간 스레드와 격리해 주세요.
WebSocketSessionDecoratorFactory는 핸들러만 감쌉니다. StompSessionManager는 Spring이 ConcurrentWebSocketSessionDecorator로 감싸기 전의 원본 세션을 등록합니다. Spring은 이 세션의 close()가 실제 소켓을 닫지 못하거나 멈출 수 있다고 명시합니다. 따라서 한 세션의 close()가 지연되면 풀 크기 1인 스케줄러에서 다른 세션의 만료 작업도 지연될 수 있습니다.
close()를 별도 executor에서 실행하거나, 제한시간 작업과 종료 호출을 격리해 주세요. IOException은 처리되지만 unchecked exception은 이 코드에서 처리되지 않습니다. 다만 scheduled task의 예외가 스케줄러 전체를 중단시키지는 않으므로, 이 예외 처리는 스케줄러 정지 방지보다 종료 실패 로깅과 개별 작업 처리를 위한 목적이어야 합니다.

StompSessionTimeoutConfig의 풀 크기 1인 스케줄러에서 세션 만료 작업이 WebSocketSession.close() 때문에
지연되지 않도록 종료 호출을 별도 executor로 분리하거나 만료 작업과 격리하세요. IOException뿐 아니라 unchecked
exception도 개별 종료 실패로 처리하고 기록해 다른 세션의 만료 처리가 계속되게 하세요.
