* Pure helpers for the Claude Code card's "config directory + environment
|

* variables" editor. The managed Claude agent stores everything in its
|

|
* ExternalAgentConfig.env; this splits that into the editable pieces and
|
||
|
|
* recombines them. CLAUDE_CODE_EXECUTABLE is owned by path discovery, so it
|
||
|
|
* is preserved across edits but never shown in the env editor.
