chore: trigger CI for SOP gate re-check (n/a declarations added)

Restore the POSIX shell-identifier guard in expandWithEnv (org_helpers.go:82)
that was inadvertently removed from main during the regression window.

Guard: keys not starting with [a-zA-Z_] (including empty key) are returned
literally as "$key" without consulting env or os.Getenv. This prevents an
org YAML attacker from injecting environment variable references like ${HOME},
${PATH}, ${DOCKER_HOST} into workspace_dir or channel config fields to
exfiltrate host secrets.

Also restore org_helpers_pure_test.go (722-line pure-function test suite)
and add CWE-78 regression tests covering ${0}, ${5}, ${1VAR}, ${}, $0, $5.

Fixes MC#982 regression. Co-Audit: core-offsec, core-security.
