"""Session-scoped environment variables — Python port of
|
|
``utils/sessionEnvVars.ts``.
|
|
|
|
These are env vars set during a session (via the upstream ``/env`` slash
|
|
command in npm) and applied only to spawned child processes — not to the
|
|
host Python REPL/agent process itself. Bash and similar tool providers
|
|
read this map to merge into ``subprocess`` environments.
|
|
|
|
Mirrors the upstream module-level singleton: callers import the helpers
|
|
directly rather than passing a registry around.
