fix(tui): stop leftover toast titles during update install

[johnnyeric]

What

When accepting the TUI update prompt, the installing notification reused the previous toast title (MCP Authentication Required) instead of an update title.

Why

SolidJS createStore merges objects, so currentToast.title leaked from the last toast when the update toast omitted title.

Change

• Replace the toast with reconcile so omitted fields do not persist
• Set an explicit Updating title on the install toast
• Add a regression test for title replacement

How to Test

1. Trigger an MCP auth toast
2. Accept an available TUI update
3. Confirm the installing toast title is Updating, not the MCP title

Code Review Summary

Status: No Issues Found | Recommendation: Merge

Incremental review of f0eb9d1..1213fd1: the commit-message error surfacing (new CommitMessageFailedError + catchDefect branch) correctly propagates the real error message, the regression test exercises the full HTTP stack with only the LLM boundary stubbed, and the httpapi-exercise changes (git-init opt-in default, --shard support, coverage-mode early return bypassing the runtime import) are internally consistent. The regenerated SDK additions (CommitMessageFailedError, WorktreeSetupReady) match server-side definitions.

lgtm — the reconcile fix correctly prevents stale toast fields from leaking across toast.show calls, the explicit Updating title matches surrounding patterns, and the regression test exercises the real store implementation without mocks.
