* `export`/`env` builtins and `$NAME` expansion): types "export

* GREETING=frostbyte" at the real interactive shell (sets it in the
|

* SHELL's own Thread.env, currentThreadSetEnv), then "envprint" (loaded
|

* on demand, /bin/envprint -- proves the freshly spawned child inherited
|
||||
* a real copy via initialEnv and that its own later userSetEnv is visible
|

* to itself), then a final bare "env" (shell.c's listing builtin) whose
|
||||
* output is the actual proof of isolation: if envprint.c's own
|
||||
* userSetEnv("GREETING", "child-mutated") had somehow reached back into
|
||||
* the PARENT shell's table (a shared-pointer bug, not the real
|
||||
* independent-copy semantics initialEnv gives), this "env" would print
|

* "child-mutated" instead of the original "frostbyte" -- the same
|
||||
* "child's own later mutation is proven not to leak back" shape
|
||||
* cwdtest.c's post-userWait getcwd() check already established for
|
||||
* per-process cwd. The actual pass/fail proof for the first two commands
|
||||
* is entirely envprint.c's own doing; this thread's only job is to type
|
||||
* the three commands and give the scheduler real time between them.
