* fix(opencode): run managed OpenCode 2 accounts on a private server
OpenCode 2's background service binds one fixed port per machine, so a
second managed account's service could never start. Launch managed
accounts with --standalone, which picks its own port.
Fixes#33780
* chore(opencode): tighten standalone rewrite comments
* fix(opencode): use a private OpenCode 2 server only when another data dir holds the service port
Users with one managed account keep the shared background service. Orca
adds --standalone only when a live upstream registration
($XDG_STATE_HOME/opencode/service.json) belongs to a different data dir,
plus a short in-process claim for launches that start together.
* fix(opencode): judge resumed accounts by their applied data dir and claim the port only for real launches
Daemon spawns consume the resume request before the private-server check runs, so
derive the launch's own data dir from the applied account env when present. Only
take the shared-port claim when the --standalone rewrite can apply.
