The `if: always()` conditional on the env-file cleanup step in both
deploy workflows is what makes the ADR-011 single-tenant runner trust
model safe: secrets land on disk before each deploy and are wiped
unconditionally afterwards. A future workflow refactor that drops
`if: always()` would silently leave plaintext secrets on the runner
on any failed deploy.
The ADR documents this; the workflow file did not. Adds a prominent
inline comment so the next reader of the YAML sees the constraint
without having to cross-reference ADR-011. No behaviour change — both
workflows still parse. Addresses @nora's round-2 suggestion on PR
#499 — "linchpin of the ADR-011 trust model".
