Siddharth Balyan 4bf0e75ae9 fix(nix): make extraPackages actually work via per-user profile (#17047)
* fix(nix): make extraPackages actually work — wire into per-user profile

#17030 deprecated extraPackages because it only set the systemd service
PATH, which the terminal backend's login-shell snapshot discards.

Instead of deprecating, fix it: set users.users.${cfg.user}.packages
so NixOS builds a per-user profile at /etc/profiles/per-user/hermes/bin.
This path is included in PATH by /etc/set-environment, which the login
shell sources, so the terminal backend's snapshot picks it up.

One line of actual logic:
  users.users.${cfg.user}.packages = cfg.extraPackages;

Verified in a NixOS VM test: su - hermes -c 'which hello' resolves
to /etc/profiles/per-user/hermes/bin/hello.

Reverts the deprecation warning and docs changes from #17030, restores
extraPackages as the recommended way to give the agent extra tools.

Container mode is unaffected — extraPackages was always native-only
(the systemd path line is inside !cfg.container.enable).

* nix: clarify additive merge semantics for extraPackages user profile
