fix: migrate msg buffer to Calcit 0.13.42

[tiye]

Summary

• upgrade the compiler and @calcit/procs runtime to Calcit 0.13.42
• upgrade @google/genai to 2.18.0
• log caught message-request errors with console.error, while retaining the UI failure state
• update Respo/respo-markdown.calcit to 0.4.25, which unwraps current Calcit Option values before rendering table headers
• retain explicit &unit event-handler results, distinct from application nil

Validation

• dependency resolution and calcit calcit.cirru --check-only with Calcit 0.13.42
• JavaScript code generation and yarn vite build --base=./
• clean browser page: no Markdown Expected list error; forced request error is surfaced through console.error
• live Gemini streaming using configured environment credentials: gemini-3.1-flash-lite and gemini-3.7-flash

Depends on Calcit 0.13.42 and Respo Markdown 0.4.25.

Suppressed comments (23)

calcit.cirru:674

• (;nil) is a comment form in Calcit, not an expression, so this handler still returns the result of the last reset! rather than explicitly returning Unit. Replace it with an actual nil expression for the typed event contract.

                              :on-click $ fn (e d!) (reset! *archived-sessions false) (reset! *viewing-archive-session false) (;nil)

calcit.cirru:705

• (;nil) is a comment form in Calcit, not an expression, so this handler still returns the result of reset! rather than explicitly returning Unit. Replace it with an actual nil expression for the typed event contract.

calcit.cirru:732

• ;nil is only a comment in Calcit, so it does not add the promised Unit return to this asynchronous event handler. Add a real nil expression after the existing effects so the Respo event contract is actually satisfied.

calcit.cirru:747

• (;nil) is a comment form in Calcit, not an expression, so this handler still returns the result of .show rather than explicitly returning Unit. Replace it with an actual nil expression for the typed event contract.
