refactor(llm): drop the inert request knobs — prefill and strict

GenerateOptions.prefill had no production setter and both adapters rejected it with LlmError('UNSUPPORTED') — its entire observable behavior was two throws, each pinned by one adapter test. DeepSeek's chat-prefix completion is a Beta feature on a base URL neither adapter targets. ToolSchema.strict was threaded through defineTool, the registry's schemas() allowlist, the deepseek wire mapping, a per-tool payload-patching pass in the pi-ai adapter, and a tool-catalog render row, yet no shipped tool set it and the internal endpoint story for strict mode was never built. Remove both fields end-to-end: the vocabulary in dsh-llm, the adapter guards and wire branches, the dsh-tools threading, the tool-catalog Strict row, the pinning tests, the core.md pastes, the adapter README rows, and the cookbook line that used prefill as the UNSUPPORTED example (now stated generically). The pi-ai payload fixup keeps the half with a job: pi-ai stamps strict:false on every serialized tool, so the fixup scrubs it unconditionally for wire parity with the hand-rolled twin (per-tool set/delete machinery gone). temperature/ stop/maxTokens are untouched — honored end-to-end by both adapters. Each knob returns with its first real producer: prefill with an adapter that implements chat-prefix completion, strict with a tool that wants it and a beta-endpoint story. RFC: docs/rfc/implemented/simplification/2026-07-04-drop-inert-request-knobs.md (moved from proposed/, amended to shipped reality); the content-block vocabulary RFC's consequence line now records prefill as producer-gated.

 ## Consequences

- Reasoning and prefill have a home without provider contortions. Multimodal content deliberately has NO core block type: the core set is limited to blocks every shipping path honors, and a multimodal feature adds its block type through the merge-extensible map in the same coordinated change that maps it in the adapters, surfaces it in the UI bridges, and prices it in compaction — see [the drop-image RFC](../simplification/2026-07-04-drop-image-content-block.md). Block cache hints likewise have no core field: DeepSeek prompt caching is automatic, so no shipping adapter can transmit a hint; a caching feature adds a `cache` field together with the adapter that honors it — see [the producer-less-variants RFC](../simplification/2026-07-04-prune-producerless-vocabulary-variants.md).

 - Every adapter pays a translation cost; the first real adapters have since validated the streaming protocol, and new adapters should continue proving their provider-specific mapping in adapter-local tests.
 - IDs that cross package boundaries are branded (`CallId`, `SessionId`, `AgentId`) — nominal typing at zero runtime cost.
