NAS maps the agent-cron bearer to a provisioned instance via an `agent:*` client or the
`hermes-cli-vps` bootstrap session (hermes-portal `server/agent-cron/instance-auth.ts`). A
container whose auth.json holds a plain `hermes-cli` user login is refused with 403
invalid_client on every arm, re-arm and list, for the life of that credential - and the
re-login users try first (`hermes auth logout nous` + device code) replaces the bootstrap
session, making it permanent. Chronos previously logged one bare warning per job and left
the jobs with no trigger at all: they only ran through the misfire sweep, minutes late.
NasCronClientError now carries the HTTP status and the OAuth `error` code. On an identity
rejection the provider logs ONE warning that names the real remedy (restore the hosted
credential from the Nous Portal; re-login cannot fix it), stops calling NAS, and starts the
built-in ticker with the gateway's own adapters/loop so scheduled jobs keep firing on time.
Transient 5xx/transport failures keep retrying on the next reconcile.
Supersedes #97566 (@wesleysimplicio), whose runtime-credential swap resolves to the same
bearer on main (`agent_key` is the access token) and so could not change the 403.
