Bug fixes and enhancements

For all platforms

• Fixed Cmd+Q (Mac) and Ctrl+Q (Windows/Linux) not fully quitting Docker Desktop. Fixes docker/for-mac#7833.
• Fixed a bug where canceling docker load left a containerd ref lock held, causing subsequent loads of the same image to fail.
• Fixed an issue where Docker Desktop made unnecessary network requests to mcp.docker.com on sign-in when MCP Toolkit was disabled, causing unexpected proxy authentication prompts.
• Fixed an issue where the search input in Gordon's session sidebar would not close if it was left empty.
• Improved Docker Desktop handling of transient rename failures caused by antivirus software accessing those files simultaneously.

For Mac

• Fixed excessive memory usage on Apple Silicon Macs by improving the Linux VM's ability to return freed container memory back to the host OS.
• Fixed a bug where containers received connections with a corrupted source IP when another container had an active outbound connection to an IP in the same subnet range. Fixes docker/for-mac#7824.
