mcp-config.json is generated in the world-readable Nix store, and the
example put an API key in an HTTP header. Remove the key from the
example and document env.<NAME>.file, which Home Manager reads at server
startup for local servers.
forCopilotFormat only checked for type == "stdio" to add back args,
missing the case where a server already has type = "local" (e.g. set
directly by a third-party module). This caused args to be absent in the
generated mcp-config.json, failing validation.
Also, running forCopilotFormat as an extraTransform meant it ran inside
transformMcpServer, which then filtered out args = [] in its cleanup
pass. Move forCopilotFormat to run after transformMcpServer so the
empty args list is preserved in the output.

`literalExpression` is intended just to signify code that needs to stay
a string that gets represented exactly as-is for docs. It has been
misused heavily and people get confused repeatedly on when or not to use
it because of the rampant misuse.
Add support for managing Copilot CLI global instructions via programs.github-copilot-cli.context, written to copilot-instructions.md under COPILOT_HOME.
Also manage custom agents and skills from inline definitions, file paths, and directories, with focused tests and a news entry covering the new options.
