Resolve provider credentials from 1Password op://vault/item/field references
at startup via the official `op` CLI, alongside the existing Bitwarden source.
Users map env-var names to references in secrets.onepassword.env; after .env
loads, each is resolved with `op read` and injected into os.environ. Auth is
whatever `op` already uses (service-account token or desktop/interactive
session) — Hermes never authenticates or installs `op` itself.
Startup-safe and fail-open: a missing binary, expired auth, a bad reference,
or an empty value each warn and fall back to existing credentials, never
blocking startup. Successful, complete pulls are cached in-process and on disk
(<hermes_home>/cache/op_cache.json, 0600) via the shared DiskCache; only
secret values are stored, never the token (auth is fingerprinted into the
key). Adds `hermes secrets onepassword {setup,status,set,remove,sync,disable}`
(aliases op/1password), config defaults, the cli-config example, docs, and
hermetic tests.
Hardening applied across both backends in env_loader: each source runs in its
own guard, config sections are coerced to dict, and cache_ttl_seconds is
coerced defensively — so a malformed secrets: section can't abort startup.
