Bug Description Feature request — reload MCP server env vars without full restart

When I update environment variables in settings.json that MCP servers depend on (e.g., adding GITHUB_PERSONAL_ACCESS_TOKEN to enable the github plugin's MCP), the only way to activate the change is to fully restart Claude Code. There's no way to verify the fix worked in the same session where I made it.

Concrete example: today I added a GitHub PAT to settings.json env to fix a "Failed to connect" error on the github plugin. I verified the token works against the endpoint via curl, but couldn't actually test that Claude Code picks it up — have to wait for the next session to find out.

Suggested capability: a claude mcp reload <name> subcommand that re-reads settings.json env and respawns the named MCP server. Or a /reload-mcp slash command in-session. Either gives a way to validate config changes in the session where they're made.

Friction this would solve: settings.json env changes for MCP-dependent plugins currently require restart-and-pray. A reload primitive removes the guesswork.
