`activate` doubled as the thing scripts sourced non-interactively, so it carried `--` argument guards and every caller had to tolerate its prompt and `hermes` function. Composition (setup sync, bootstrap Python, pm env) now lives in scripts/_activation.sh, and there are two consumers: - `activate`: interactive, reversible (`deactivate`). - new `scripts/run-in-hermes-env CMD...`: applies the env to one process and execs into it. Replaces `scripts/_hermes-python`; every Python script's shebang and `scripts/run_tests.sh` (which re-executes itself under it, however it was launched) use it. `pm.environments --format sh` emits the env as shell exports, so the inline JSON-to-export Python is gone from `activate`. An install that did not build the test environment now reads as stale for every consumer. Tests are split along the same seams: activation support fixtures, bash/ps1 activation, env-script quoting, and the runner's staleness.

"""``pm.environments.shell_exports``: the composed environment as a script a shell can evaluate.

|
|
|
Both ``activate`` and ``scripts/run-in-hermes-env`` evaluate this output, so the
|
|
contract is what a real shell reads back: any value survives the quoting, and
|
|
names the shell cannot assign are left out instead of failing the whole script.
