cf249586a9 feat(antigravity): configurable signature cache with bypass-mode validation 
Antigravity 的 Claude thinking signature 处理新增 cache/bypass 双模式，
并为 bypass 模式实现按 SIGNATURE-CHANNEL-SPEC.md 的签名校验。

新增 antigravity-signature-cache-enabled 配置项（默认 true）：
- cache mode（true）：使用服务端缓存的签名，行为与原有逻辑完全一致
- bypass mode（false）：直接使用客户端提供的签名，经过校验和归一化

支持配置热重载，运行时可切换模式。

校验流程：
1. 剥离历史 cache-mode 的 'modelGroup#' 前缀（如 claude#Exxxx → Exxxx）
2. 首字符必须为 'E'（单层编码）或 'R'（双层编码），否则拒绝
3. R 开头：base64 解码 → 内层必须以 'E' 开头 → 继续单层校验
4. E 开头：base64 解码 → 首字节必须为 0x12（Claude protobuf 标识）
5. 所有合法签名归一化为 R 形式（双层 base64）发往 Antigravity 后端

非法签名处理策略：
- 非严格模式（默认）：translator 静默丢弃无签名的 thinking block
- 严格模式（antigravity-signature-bypass-strict: true）：
  executor 层在请求发往上游前直接返回 HTTP 400

按 SIGNATURE-CHANNEL-SPEC.md 解析 Claude 签名的完整 protobuf 结构：
- Top-level Field 2（容器）→ Field 1（渠道块）
- 渠道块提取：channel_id (Field 1)、infrastructure (Field 2)、
  model_text (Field 6)、field7 (Field 7)
- 计算 routing_class、infrastructure_class、schema_features
- 使用 google.golang.org/protobuf/encoding/protowire 解析

- resolveThinkingSignature 拆分为 resolveCacheModeSignature / resolveBypassModeSignature
- hasResolvedThinkingSignature：mode-aware 签名有效性判断
  （cache: len>=50 via HasValidSignature，bypass: non-empty）
- validateAntigravityRequestSignatures：executor 预检，
  仅在 bypass + strict 模式下拦截非法签名返回 400
- 响应侧签名缓存逻辑与 cache mode 集成
- Cache mode 行为完全保留：无 '#' 前缀的原生签名静默丢弃

endpoint and cache it for 6 hours. Falls back to 1.21.9 if the API

1f8f198c45 feat: passthrough upstream response headers to clients 
CPA previously stripped ALL response headers from upstream AI provider
APIs, preventing clients from seeing rate-limit info, request IDs,
server-timing and other useful headers.

Changes:
- Add Headers field to Response and StreamResult structs
- Add FilterUpstreamHeaders helper (hop-by-hop + security denylist)
- Add WriteUpstreamHeaders helper (respects CPA-set headers)
- ExecuteWithAuthManager/ExecuteCountWithAuthManager now return headers
- ExecuteStreamWithAuthManager returns headers from initial connection
- All 11 provider executors populate Response.Headers
- All handler call sites write filtered upstream headers before response

Filtered headers (not forwarded):
- RFC 7230 hop-by-hop: Connection, Transfer-Encoding, Keep-Alive, etc.
- Security: Set-Cookie
- CPA-managed: Content-Length, Content-Encoding

8c7c446f33 fix(gemini): preserve displayName and description in models list 
Previously GeminiModels handler unconditionally overwrote displayName
and description with the model name, losing the original values defined
in model definitions (e.g., 'Gemini 3 Pro Preview').

Now only set these fields as fallback when they are missing or empty.

c7e8830a56 refactor(thinking): pass source and target formats to ApplyThinking for cross-format validation 
Update ApplyThinking signature to accept fromFormat and toFormat parameters
instead of a single provider string. This enables:

- Proper level-to-budget conversion when source is level-based (openai/codex)
  and target is budget-based (gemini/claude)
- Strict budget range validation when source and target formats match
- Level clamping to nearest supported level for cross-format requests
- Format alias resolution in SDK translator registry for codex/openai-response

Also adds ErrBudgetOutOfRange error code and improves iflow config extraction
to fall back to openai format when iflow-specific config is not present.
