When using non-Anthropic providers (Ollama, Gemini, Codex), the
underlying call to queryHaiku for session title generation fails.
Previously, this caused the catch block to return null, leaving the
terminal tab permanently stuck on 'Claude Code'.
Now, when the API call fails, we gracefully derive a title locally from
the user's first message (first 7 words, sentence-cased), ensuring
users still see a meaningful session title in their terminal tab.
Squash the current repository state back into one baseline commit while
preserving the README reframing and repository contents.
Constraint: User explicitly requested a single squashed commit with subject "asdf"
Confidence: high
Scope-risk: broad
Reversibility: clean
Directive: This commit intentionally rewrites published history; coordinate before future force-pushes
Tested: git status clean; local history rewritten to one commit; force-pushed main to origin and instructkr
Not-tested: Fresh clone verification after push
