fix(nix): ship the OpenCode v2 bridge plugin in the daemon closure (#5988)

The Nix package copies only what scripts/trace-daemon.mjs lists. The list
named the v1 bridge bundle but not opencode/v2/bridge-plugin.bundle.mjs,
so creating an OpenCode v2 agent from the Nix package failed with
"Bundled OpenCode bridge plugin artifact is missing".

List every bridge bundle under opencode/, and add a dist test that
installs the traced closure the way nix/package.nix does and loads the
bridge plugin for each OpenCode version from it.

Closes #5926
