feat(cli): Supports stopping HTTPS tunnels and optimizes configuration display logic.

- Added support for HTTPS tunnel types to the `drip stop` command and updated the example documentation.
- Optimized token display logic to adapt to token formats of different lengths.
- Adjust the alignment of FrameHandler buffer read/write and timeout configuration formats.
- Move the error handling logic location to ensure data read integrity.
- Introducing context to control request lifecycle and supporting cancel transfer in proxy handlers
- The hop-by-hop header judgment format in the unified response header filtering rules
- Add a context-aware streaming request cancellation mechanism and extend the channel cleanup timeout.
- Add a context control field to the TCP connection structure to support connection lifecycle management.
- Format the httpResponseWriter field comments
