Updates the Mux implementation to maintain a per-stream circular buffer of recent messages. When a new stream registers, it receives the buffered history immediately. This ensures that new websocket connections to a reverse shell receive recent output context. The default buffer size is 1KB and is configurable. Only messages with kind "data" (or unspecified) are buffered.

Implements a circular buffer for stream history in the Mux to provide context to new connections. Refactors `sessionBuffer` to be reusable for reordering messages before writing to history. Ensures that history is written in the correct order even if pubsub messages arrive out of order. Uses a ring buffer implementation for `CircularBuffer` to minimize allocations. Added comprehensive tests for history replay and ordering.
Refactors the `Mux.Start` loop to use a background poller goroutine and a `select` statement. This ensures that registration and unregistration requests are processed immediately, even if no pubsub messages are arriving. This fixes the issue where new reverse shell connections would not receive context/history until the next message (e.g., user input) was sent. Also verified existing history replay and ordering logic.

I've updated the PR to ensure the background poller is robust against transient errors (restoring the original loop-on-error behavior) and cleaned up unused internal methods. I unfortunately cannot view the attached |
Updates the background poller in `Mux.Start` to retry on errors (logging them) instead of exiting, ensuring the Mux remains active even if transient subscription errors occur. Also removes dead code (`registerStreams` and `unregisterStreams` methods) which are now handled inline within the `select` loop. Verified that history replay and message handling functionality remains correct.
