Michal 1acd8b58bc feat(db): Llm.kind discriminator + virtual-provider lifecycle (v1 Stage 1) ...

First step of the virtual-LLM feature. A virtual Llm row is one that
gets *registered by an mcplocal client* rather than created via
\`mcpctl create llm\`. Its inference is relayed back through an SSE
control channel to the publishing session (mcpd routes added in
Stage 3). The lifecycle fields below let mcpd reap stale rows when
the publisher goes away.

Schema additions:
- enum LlmKind (public | virtual). Default public.
- enum LlmStatus (active | inactive | hibernating). Default active.
  hibernating is reserved for v2 wake-on-demand.
- Llm.kind, providerSessionId, lastHeartbeatAt, status, inactiveSince.
- @@index([kind, status]) for the GC sweep.
- @@index([providerSessionId]) for the reconnect lookup.

All existing rows backfill with kind=public/status=active so v1 is
purely additive — public LLMs ignore the lifecycle columns entirely.

7 new prisma-level assertions in tests/llm-virtual-schema.test.ts
cover: defaults, persisting kind=virtual + lifecycle together, the
active→inactive flip, hibernating value, enum rejection, the
(kind,status) GC index, the providerSessionId reconnect index.

mcpd suite still 801/801 (regenerated client) and typecheck clean.
