kevinveenbirkenbachandClaude Opus 5 b3ce43a596 fix(security): require no_log on every task that carries a credential ...

At -vvv Ansible prints each module argument and result, so a password in
a command line, a request body, a header or a fact lands in the deploy
log. Nothing enforced masking outside the MCP task files, and no check
looked at parents at all.

A new lint, test_credential_tasks_are_masked, finds tasks whose printed
parts (module arguments, environment, loop) reference an identifier ending
in password, secret, token, api_key or private_key, or
secrets.credentials. A task passes when it or an enclosing block sets
no_log, when every file that pulls it in does so through include_tasks
with apply.no_log or import_tasks with no_log (transitively), when the
secret only reaches a parameter the module masks itself, or when the
module masks its values. no_log on an include_tasks task itself does not
count, because it does not reach the included tasks. The rule can be
suppressed per task with `# nocheck: credential-masking`, now listed in
the suppression catalog, and the lint tests its parent and suppression
logic on synthetic cases.

It found 39 unmasked tasks in 19 roles, all real: join tokens, client
secrets, API tokens in Cloudflare headers, database passwords in
command lines, the ChatGPT bot login body and more. Each now sets
no_log from MASK_CREDENTIALS_IN_LOGS. The sys-dns-hetzner-rdns alias
hetzner_no_log, which only restated that switch, is gone.

Not covered yet: template and copy tasks whose rendered file carries a
secret print it as a diff under --diff.
