Portal reasoning capabilities were held only in memory, so a process that
had not yet fetched them answered "unknown" — and on that answer the Nous
profile drops the disable rather than risk a 400. A short-lived process
(`hermes -p`, a cron job, a freshly booted gateway) is always in that
state, so every one of those runs silently ignored "thinking off" and
billed the user for reasoning they had turned off.
The parsed catalog is now mirrored to `cache/reasoning_caps.json`, keyed
by the URL it came from, and hydrated on a cold lookup without touching
the network. Every picker and pricing fetch already pulls that same
document, so they seed the mirror for free.
The catalog URL itself now resolves through the same ladder as the rest
of the Nous catalog reads (`NOUS_INFERENCE_BASE_URL` → credential base →
production) instead of being pinned to production, which had a staging
profile deciding the reasoning-mandatory question from prod's answers.
Keying the mirror by URL keeps those deployments apart.
