Core v1.7.8

Core Release v1.7.8

• fix: stop dropping replayed reasoning when a message carries a non-nil but empty ContentBlocks list - the Anthropic, Bedrock and Cohere converters now fall through to ResponsesReasoning instead of letting an else if shadow it (#5982)
• fix: never send Bedrock a reasoning block with an absent text key - it is omitempty, so a nil pointer dropped the field entirely and Converse rejected the turn with "Member must not be null", on both the Responses and chat conversion paths (#5982)
• fix: attach the replayed signature to the first Bedrock reasoning summary block instead of discarding it, routed through reasoningSignatureForBedrock so the empty-string guard matches every other signature site (#5982)
• fix: force the thinking key onto Bedrock invoke thinking blocks even when the text is empty, so a signature-only replay block no longer serializes to a shape Bifrost's own decoder drops (#5982)
• fix: emit Cohere encrypted reasoning alongside the summary rather than instead of it, and parse the [ENCRYPTED_REASONING: ...] marker back into EncryptedContent on ingress so it no longer reaches clients as visible reasoning text (#5982)
• fix: base64-decode encrypted_content before assigning it to a Gemini thoughtSignature on the streaming path, which previously shipped a double-encoded signature Gemini could not verify (#5982)
• fix: carry Gemini thoughtSignature off thought parts into encrypted_content and the reasoning block signature, and emit signature-only thought parts, so clients can replay them (#5982)
• fix: stop skipping standalone Gemini reasoning messages when converting Responses history to Gemini contents - thought text is now resent as the thinking guide requires, and the signature is emitted when no preceding function call consumed it (#5984)
• fix: carry a consumed reasoning item's thought text alongside the signature the preceding Gemini function call took from it, so the thought block reaches Gemini unmodified (#5984)
