fix(stream): normalize delta.reasoning alias and separate reasoning in client response (#771)

* fix(stream): normalize delta.reasoning to reasoning_content in SSE streaming

NVIDIA kimi-k2.5 (and potentially other providers) send reasoning
tokens as `delta.reasoning` in SSE streaming chunks instead of the
standard OpenAI `delta.reasoning_content` field. This caused reasoning
content to be silently dropped during stream passthrough — clients
received only the final answer with no reasoning separation.

The non-streaming sanitizer (responseSanitizer.ts) already handled this
alias, but the streaming pipeline did not.

Fix applied in 4 locations:
- stream.ts passthrough: normalize + force re-serialize sanitized chunk
- stream.ts translate: accumulate reasoning from delta.reasoning
- sseParser.ts: collect delta.reasoning in parseSSEToOpenAIResponse
- streamPayloadCollector.ts: collect delta.reasoning in buildOpenAISummary

* fix: eliminate injectedUsage reuse bug and add reasoning alias tests

- Detect delta.reasoning alias before sanitizeStreamingChunk() which
  already normalizes it, removing dead post-sanitization normalization
- Replace injectedUsage reuse with separate needsReserialization flag
  so reasoning re-serialization cannot block finish_reason/usage
  mutations on the same SSE chunk (fixes CRITICAL review finding)
- Add unit test for parseSSEToOpenAIResponse reasoning alias
- Add unit test for buildStreamSummaryFromEvents reasoning alias

* fix(stream): separate reasoning from content in passthrough response body

The passthroughAccumulatedContent variable was mixing delta.content and
delta.reasoning_content into one string, causing the client_response
log and responseBody to lose reasoning separation.

- Add passthroughAccumulatedReasoning accumulator for reasoning deltas
- Set message.reasoning_content in responseBody when reasoning exists
- Only accumulate delta.content into passthroughAccumulatedContent

* fix: trim leading whitespace from assembled content in log summaries

NVIDIA and other providers emit token deltas with leading spaces
(e.g. ' The', ' user'). When joined, these produce a leading space in
the provider_response and parsed non-streaming response logs. Trim
the joined content and reasoning_content in both buildOpenAISummary
and parseSSEToOpenAIResponse for consistent log output.

* fix(stream): split combined reasoning+content deltas into separate SSE events

Some providers (e.g. NVIDIA NIM) send transition chunks with both
`delta.reasoning` and `delta.content` in the same SSE event.
After sanitization this becomes `reasoning_content` + `content`,
which violates the standard OpenAI streaming contract where these
fields are never mixed. Clients using if/else logic (LobeChat, etc.)
skip content when reasoning_content is present, losing the first
content token.

Split such combined chunks into two separate SSE events:
1. Reasoning-only event (finish_reason=null, no usage)
2. Content-only event (carries finish_reason and usage)

 ## [Unreleased]
 
+---
+
+## [3.3.0] - 2026-03-29
+
+### ✨ Enhancements & Refactoring
+
+- **Release Stabilization** — Finalized v3.2.9 release (combo diagnostics, quality gates, Gemini tool fix) and created missing git tag. Consolidated all staged changes into a single atomic release commit.
+
+### 🐛 Bug Fixes
+
+- **Auto-Update Test** — Fixed `buildDockerComposeUpdateScript` test assertion to match unexpanded shell variable references (`$TARGET_TAG`, `${TARGET_TAG#v}`) in the generated deploy script, aligning with the refactored template from v3.2.8.
+- **Circuit Breaker Test** — Hardened `combo-circuit-breaker.test.mjs` by injecting `maxRetries: 0` to prevent retry inflation from skewing failure count assertions during breaker state transitions.
+
+---
+
+## [3.2.9] - 2026-03-29
+
+### ✨ Enhancements & Refactoring
+
+- **Combo Diagnostics** — Introduced a live test bypass flag (`forceLiveComboTest`) allowing administrators to execute real upstream health checks that bypass all local circuit-breaker and cooldown state mechanisms, enabling precise diagnostics during rolling outages (PR #759)
+- **Quality Gates** — Added automated response quality validation for combos and officially integrated `claude-4.6` model support into the core routing schemas (PR #762)
+
+### 🐛 Bug Fixes
+
+- **Tool Definition Validation** — Repaired Gemini API integration by normalizing enum types inside tool definitions, preventing upstream HTTP 400 parameter errors (PR #760)
+
+---
+
+## [3.2.8] - 2026-03-29
+
+### ✨ Enhancements & Refactoring
+
+- **Docker Auto-Update UI** — Integrated a detached background update process for Docker Compose deployments. The Dashboard UI now seamlessly tracks update lifecycle events combining JSON REST responses with SSE streaming progress overlays for robust cross-environment reliability.
+- **Cache Analytics** — Repaired zero-metrics visualization mapping by migrating Semantic Cache telemetry logs directly into the centralized tracking SQLite module.
+
+### 🐛 Bug Fixes
+
+- **Authentication Logic** — Fixed a bug where saving dashboard settings or adding models failed with a 401 Unauthorized error when `requireLogin` was disabled. API endpoints now correctly evaluate the global authentication toggle. Resolved global redirection by reactivating `src/middleware.ts`.
+- **CLI Tool Detection (Windows)** — Prevented fatal initialization exceptions during CLI environment detection by catching `cross-spawn` ENOENT errors correctly. Adds explicit detection paths for `\AppData\Local\droid\droid.exe`.
+- **Codex Native Passthrough** — Normalized model translation parameters preventing context poisoning in proxy pass-through mode, enforcing generic `store: false` constraints explicitly for all Codex-originated requests.
+- **SSE Token Reporting** — Normalized provider tool-call chunk `finish_reason` detection, fixing 0% Usage analytics for stream-only responses missing strict `<DONE>` indicators.
+- **DeepSeek <think> Tags** — Implemented an explicit `<think>` extraction mapping inside `responsesHandler.ts`, ensuring DeepSeek reasoning streams map equivalently to native Anthropic `<thinking>` structures.

+## [3.2.8] - 2026-03-29
+
+### ✨ Enhancements & Refactoring
+
+- **Docker Auto-Update UI** — Integrated a detached background update process for Docker Compose deployments. The Dashboard UI now seamlessly tracks update lifecycle events combining JSON REST responses with SSE streaming progress overlays for robust cross-environment reliability.
+- **Cache Analytics** — Repaired zero-metrics visualization mapping by migrating Semantic Cache telemetry logs directly into the centralized tracking SQLite module.
+
+### 🐛 Bug Fixes
+
+- **Authentication Logic** — Fixed a bug where saving dashboard settings or adding models failed with a 401 Unauthorized error when `requireLogin` was disabled. API endpoints now correctly evaluate the global authentication toggle. Resolved global redirection by reactivating `src/middleware.ts`.
+- **CLI Tool Detection (Windows)** — Prevented fatal initialization exceptions during CLI environment detection by catching `cross-spawn` ENOENT errors correctly. Adds explicit detection paths for `\AppData\Local\droid\droid.exe`.
+- **Codex Native Passthrough** — Normalized model translation parameters preventing context poisoning in proxy pass-through mode, enforcing generic `store: false` constraints explicitly for all Codex-originated requests.
+- **SSE Token Reporting** — Normalized provider tool-call chunk `finish_reason` detection, fixing 0% Usage analytics for stream-only responses missing strict `<DONE>` indicators.
+- **DeepSeek <think> Tags** — Implemented an explicit `<think>` extraction mapping inside `responsesHandler.ts`, ensuring DeepSeek reasoning streams map equivalently to native Anthropic `<thinking>` structures.
