Shared parts, not a shared scheduler (agreed): nisse-review will have its
own small scheduler; a common one waits until two exist to compare.

- nisse_core.loop.driver: the driver run, moved; the agent names its
  waiting tools per run (nisse-dev's are WAITING_TOOLS), and execution
  goes to any Executor (ToolOutcome moves with it).
- nisse_core.loop.tools: the tool helper and the tools any agent offers
  (notes, memory, memory_done, ask_expert); nisse_core.loop.expert.
- nisse_core.knowledge.handlers: Knowledge, the vault and memory as
  control tools, the index and prompt text, out of LoopAgent.
- nisse_core.config: file reading, references, people, tuning sections of
  the agent's own, LLM numbers, the vault.
- New core tests: a driver run with a non-workspace executor and the
  agent's own waiting set; Knowledge alone; the shared config pieces.

Docs: the Development Plan marks M7.2 done; Architecture Part L and the
nisse-core README name the new parts.

"""`ask_expert` (architecture L9).
The one case delegation does not cover: a question needing no repo access —
"which of these two approaches is better", "is this API deprecated". A single
stateless call, a text answer, no session state, no diff application.
Two constraints from L9 shape the implementation:
**Structured output is contracted at the prompt level, not the API level.**
Vendors differ on JSON mode and schema enforcement, so the answer is parsed and
validated against a local schema, with one retry. This runs over LiteLLM's
*normalized* route, which L9 reserves for calls where fidelity is cheap.
**A per-task budget**, so a confused executor cannot spend twenty consults
circling. The count comes from the canonical log rather than a counter in
memory: it survives a restart, and it is observable from outside the model,
which is the same reasoning L9 applies to escalation triggers.
Consults are recorded as ``delegation_started`` / ``delegation_completed`` with
role ``expert``. That is deliberate — L9 wants a "consult/delegation eval
set", and reusing the composite events gets consult evaluation for free rather
than inventing a parallel record.
