nisse-core: group modules into packages by architecture section

A pure move; behaviour unchanged.

- models (L9, L7): llm, catalog, probe, render, render_anthropic, context
- log (L7, L6): canonical, views
- state (L8): store (was state), reconcile, worker, cancel, dump
- knowledge (L10, L6.4): vault, memory
- conversation (L5): transport, matrix
- execution (L13): ssh (was execution), testing
- authority (P3, P4, L4): actions
- gitea, oplog, envfile stay at the top until each gains a second module.

Every import, monkeypatch target, script and doc reference rewritten.

 # nisse-core
 
 The shared library the Nisse agents sit on (Part L of the architecture). It
-never imports an agent.
+never imports an agent. Packages follow the architecture's sections:
 
-- **Transcript and models:** `canonical` (the log's events, L7), `render` and
-  `render_anthropic`, `llm` (the one client, L9), `catalog` and `probe` (what
-  the models are), `context` (fitting a request to its window, L6), `views`
-  (what each role is shown of the others).
-- **Durability:** `state` (the store, L8; an agent subclasses it for its own
-  tables, roles and views), `reconcile`, `worker`, `cancel`, `dump`.
-- **Conversation:** `transport`, `matrix` (L5).
-- **Execution:** `execution` (SSH to a tool VM, L13); `testing` (a throwaway
-  sshd for tests).
-- **Knowledge:** `vault` (L10), `memory` (L6.4).
-- **Operations:** `oplog`, `envfile` (L12); `gitea` (the tracker and forge, L1).
-- **Authority:** `actions` (P3, P4, L4): `Action`, `Verdict`, and static
-  reading of shell commands, which each agent's fast-path rules build on
-  (`nisse-dev`'s are in `nisse_dev.loop.actions`).
+- `models` (L9, L7): `llm` (the one client), `catalog` and `probe` (what the
+  models are), `render` and `render_anthropic` (request bodies from the log),
+  `context` (fitting a request to its window, L6).
+- `log` (L7, L6): `canonical` (the log's events), `views` (what each role is
+  shown of the others).
+- `state` (L8): `store` (an agent subclasses `StateStore` for its own tables,
+  roles and views), `reconcile`, `worker`, `cancel`, `dump`.
+- `knowledge` (L10, L6.4): `vault`, `memory`.
+- `conversation` (L5): `transport`, `matrix`.
+- `execution` (L13): `ssh` (SSH to a tool VM); `testing` (a throwaway sshd for
+  tests).
+- `authority` (P3, P4, L4): `actions` (`Action`, `Verdict`, and static reading of
+  shell commands, which each agent's fast-path rules build on; `nisse-dev`'s are
+  in `nisse_dev.loop.actions`).
+- At the top, until each gains a second module: `gitea` (the tracker and forge,
+  L1), `oplog` and `envfile` (L12).
 
-The loop is still `nisse-dev`'s, until `nisse-ops` has one to share it with
-(Development Plan M7.2).
+The parts of a loop (`loop`) and shared configuration arrive with Development
+Plan M7.2; each agent keeps its own scheduler.
