fix: upgrade Calcit messaging runtime

[tiye]

Summary

• upgrade Calcit/@calcit/procs and the Respo dependency chain, including alerts.calcit 0.10.26
• replace nullable chat text/thinking state with concrete strings and normalize legacy persisted state
• isolate GenAI stream decoding behind a typed StreamChunk adapter and guard non-string FFI values
• preserve Reply submission with the released alerts callback behavior
• replace unsupported native prompt() API-key collection with an alerts prompt, validate blank keys, and map each provider model to its storage key
• route the existing Claude Sonnet 4.5 menu item through OpenRouter instead of the Gemini fallback

Validation

• caps --strict
• yarn install --immutable
• calcit edit format
• calcit --check-only
• calcit test (4 passed)
• calcit analyze quality --baseline config/calcit-quality.json
  • codeNil: 41 -> 21
  • unresolved: 106 -> 85
  • schemaDynamic: 65 -> 64
• calcit js
• yarn vite build --base=./
• browser smoke: no initial undefined; Reply opens the API-key prompt when the provider key is absent; blank Save shows validation; no new native-prompt error is appended

🟡 Changes recommended

The new GenAI chunk decoder still performs unconditional nested property/index reads that can throw on partial chunk shapes, and the legacy :done? default in normalization can mis-render the UI as “Streaming...” on load.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

Upgrades the Calcit messaging/runtime and Respo dependency chain, while tightening the chat state and streaming pipeline by replacing nullable fields with concrete strings and centralizing GenAI stream chunk decoding behind a typed adapter.

Changes:

• Bump @calcit/procs to 0.13.72 and update Calcit/Respo Calcits in deps.cirru.
• Refactor streaming handling: introduce StreamChunk + decode-genai-chunk, and enforce string-only streaming text via stream-text.
• Normalize legacy persisted ChatState into the new non-nullable schema (answer/thinking as strings; model as tag) and update UI call sites accordingly.
