Core Release v1.6.3

• feat: added DeepSeek as a first-class provider (#4852)
• feat: added bedrock_mantle as a first-class provider with native-Anthropic and OpenAI-compatible routing and SigV4 key config (#4736, #4737)
• feat: added JWT Bearer authentication path for /mcp with session validation, a virtualKeysByID secondary index, and cached signing key and VK lookups (#4508, #4783)

• feat: added IPv6 support (#4895)
• feat: added ClickHouse support for the log store (#4748)
• feat: extended Bedrock vendor-prefix pricing fallback to OpenAI, Google, and xAI models and folded bedrock_mantle onto bedrock lookups (#4924)
• feat: added is_deprecated to model pricing and catalog responses and mark deprecated models instead of filtering them (#4779, #4792, #4936)
• feat: added latency info on errors (#4867, #4876)
• feat: added multiple teams, customers, and business units to connectors (#4875)

• fix: emit contentBlockStop events on the Bedrock ConverseStream egress so consumers that assemble messages on block boundaries get complete content (#4923, closes #4262) (thanks @fus3r!)

• fix: emit reads-only cached_tokens in usage per the OpenAI spec so cache writes are not priced as cache reads (#4906, closes #4816) (thanks @fus3r!)

• fix: web fetch fixes (#4945)
• fix: set SecretTypePlainText for plain-text JSON and non-prefixed secret values (#4946) and check whether virtual key values are secrets (#4927)

• fix: cost for image generation and image edit streaming (#4802, closes #4777)
• fix: Perplexity Responses API compatibility (#4813)
• fix: signal Bedrock max_output_tokens truncation on the Responses API (#4680, closes #4679) (thanks @jeremym-tanium!)
