* fix(streaming): dedupe content, recover reasoning, unique tool IDs
When tool calls are discovered only during final parsing (after the
streaming token callback returns), processTools' default switch branch
used to emit the full accumulated content alongside the tool_call args
chunk. Clients that accumulate delta.content per the OpenAI streaming
contract end up showing every narration line twice. Three related bugs
in the same flush path:
1. Content duplication: the args chunk carried Content:textContentToReturn
even though the text had already been streamed token-by-token via
the token callback, so delta.content was both the running total and
bundled with tool_calls in one delta (two spec violations).
2. Reasoning drop: when the C++ autoparser surfaces reasoning only as
a final aggregate (no incremental tokens), the callback never emits
it and the flush branch didn't either, silently losing it.
3. tool_call ID collision: empty ss.ID fell back to the request id, so
multiple empty-ID calls in the same turn all shared the same id,
breaking tool_result matching by tool_call_id.
Extracted the block into buildDeferredToolCallChunks (pure function,
unit-testable) and added 19 Ginkgo specs covering streamed vs.
not-streamed content/reasoning, single vs. multi call, and
incremental-vs-deferred emission. Every case asserts the invariant
that no delta carries both non-empty Content/Reasoning and non-empty
ToolCalls.
Fix summary:
- emit reasoning in its own leading chunk when !reasoningAlreadyStreamed
- emit role+content in their own chunks when !contentAlreadyStreamed
- drop Content from the tool_call args chunk
- fallback to fmt.Sprintf("%s-%d", id, i) for empty ss.ID so calls stay
uniquely addressable
Reproduced live against qwen3.6-35b-a3b-apex served by LocalAI with
the C++ autoparser; the full-content replay chunk that preceded each
tool_calls block is gone after the fix.

* fix(streaming): dedupe reasoning in the noActionToRun final chunk
extractor.Reasoning() returns only the Go-side extractor's lastReasoning
accumulator (pkg/reasoning/extractor.go:129). ChatDelta reasoning
coming through ProcessChatDeltaReasoning lives in a separate
accumulator (cdLastStrippedReasoning) that Reasoning() does not
expose. The "reasoning != \"\" && extractor.Reasoning() == \"\"" guard
therefore fires exactly when the autoparser streamed reasoning
incrementally via the callback — producing a duplicate final delivery.
Replace both guard sites in the noActionToRun branch with the
sentReasoning flag introduced in the previous commit. Extract the
closing-chunk logic into buildNoActionFinalChunks so the refactor is
testable; the helper mirrors buildDeferredToolCallChunks.
Add Ginkgo coverage for both the content-streamed and
content-not-streamed paths: reasoning is dropped when it was streamed,
delivered once when it arrived only as a final aggregate, and omitted
when empty. Metadata invariants carried over from the sibling helper.

* fix(streaming): detect noActionToRun anywhere in functionResults
The previous condition only looked at functionResults[0].Name, which
misbehaved when a real tool call followed a noAction sentinel — the
noAction shadowed the real call and the whole turn was treated as a
question to answer, silently dropping the tool call. The mirror case,
[realCall, noActionCall], fell into the default branch and emitted the
noAction entry as if it were a real tool_call.
Replace with hasRealCall, which scans the slice and returns true as
soon as it finds a non-noAction entry. noActionToRun now matches the
semantic intent: "every entry is the noAction sentinel (or the slice
is empty)".
Note: this does not change incremental emission, where noAction
entries may still be forwarded as tool_call chunks by the XML/JSON
iterative parsers. That is a separate layer (functions.Parse*) and
addressing it requires threading noAction through the parser APIs —
out of scope for this change.
