Resolve the model catalog table conflict in docs/public/core-concepts/models.mdx
by keeping both changes: this branch's `kimi` -> `moonshot` provider rename for
the Kimi rows, and main's new DeepSeek V4 rows.

`StreamStart` was supposed to mean "the provider is responding", but
each decoder decided for itself when to emit it, so it meant something
different per dialect:
anthropic on the `message_start` frame
bedrock on the `messageStart` frame
openai_responses latched on the first SSE event
gemini latched on the first chunk
openai_compatible never — Chat Completions has no opening frame
A consumer could not rely on it, which is why the inference-bracket
work keyed its first-output edge on content kind instead.
Ownership moves to the two loops that drive decoders — the shared SSE
loop in `transport.rs` and the AWS event-stream loop in the bedrock
provider — each emitting exactly one `StreamStart` immediately before
handing over the first framed event. The invariant is now structural:
it cannot depend on a dialect having a particular opening frame,
because no decoder is involved in producing it. `StreamDecoder`
documents that decoders must not emit it, and the four that did no
longer do.
Only `openai_compatible` changes observably, gaining the event it never
had; the other three dialects' snapshots are byte-identical, because
their opening frame was already the first framed event. The six
updated `openai_compatible` snapshots each differ by exactly one
leading `stream_start` and nothing else.
Each dialect also gets an explicit `stream_opens_with_stream_start`
assertion. The snapshots already cover this, but a snapshot can be
re-accepted silently, and this is the one event a liveness consumer
needs to hold for every provider.
No behavior change to the agent's inference bracket:
`first_output_kind()` maps `StreamStart` to `None`, so the bracket
still opens on observed content and keeps reporting which kind
arrived. The point of this change is that a content-agnostic edge now
exists at all — the one-shot coverage follow-up needs it, and it is
strictly earlier than first content.

Chat Completions only emits the trailing usage chunk when the request sets
`stream_options: {"include_usage": true}`. The openai_compatible codec never
sent it, so providers that follow the spec strictly returned no usage at all
on streamed responses. Every message came back with zero tokens, and the
catalog cost estimate multiplied those zeros into $0.
Kimi is the visible case: a run's kimi-k3 stages report 0 tokens and no
dollars, while an openrouter stage in the same run bills normally because
OpenRouter volunteers usage (and an in-band cost) without being asked.
Send the opt-in whenever we stream. Providers that already volunteer usage
accept the field and are unaffected.

Normalize the readable reasoning providers already return into a
canonical `ReasoningOutput` and carry it through the `agent.message`
run event to storage, SSE, and JSONL.
The shape is derived from the final response's canonical message
content rather than stored a second time, so there is no duplicate
source of truth and retried or replaced streaming buffers never
become durable reasoning. OpenAI-compatible `reasoning_details` are
now preserved verbatim as an opaque content part; only known readable
members are normalized out of them, leaving encrypted entries for a
later provider-aware replay phase.
This phase is passive: no request parameters change, no capability
guessing, and no newly observed provider field is replayed.

The crate reorganization renamed lib/crates/ to lib/apps|components|foundation/.
Git followed all modified files across the rename; the only conflict was the
newly added codec/cache.rs, now placed at lib/components/fabro-llm/src/codec/cache.rs.
