docs(architecture): drop the stale idle-recompress table note

The provider table is gone, so the sentence that explained its ollama row is gone too.

 - **Idle (end-of-turn)** — An interactive turn can end with a reply and then sit idle with no tool batch to intercept; the governor requests a continuation at that pause and compacts when it arrives. An operator message that races the continuation still compacts first, then re-enters inference to answer it.
 - **Idle recompress past the provider TTL** — Cache expiry does not compact. Stored turns stay. When settings set `anthropicCachePrompt`, and the saved Anthropic-protocol cache write is at least 5 minutes old, the pre-inference context transform stubs old tool-result bodies on the outgoing prompt only. `turns.jsonl` is not rewritten. The setting defaults off.
 
-The `ollama` table key is the bare provider segment; the harness stamps slash-form on `sourceId` (`ollama/default` / `ollama/<instance>`), with `provider: openai-compatible` (`buildOpenAISource`) and a bare model (`llama3` / `qwen3`). Idle-recompress disable matches via `isOllamaProviderId` on that `sourceId` (`src/provider/ollama.ts`), not by looking up slash-form as a table key.

 - **Operator `/compact`** — A first-class slash command folds now without waiting for the occupancy governor. Optional trailing instructions go to the summarizer (empty uses the default structured fold) and are stored on the compact record so later auto-folds still see them. Director rebuild (`/model`, interrupt, resume) restores those instructions from the latest compact record's parameters. An in-flight turn uses the same pair-safe compact-then-continue hop as threshold compact; an idle compact shows the fold and does not start a new turn.
 - **Overflow recovery** — A `context_overflow` inference error would otherwise become a terminal error reply; the governor compacts and retries instead, bounded so a history the compactor cannot shrink does not loop forever. Overflow ignores hysteresis for the compact itself.
