## What changed


- Use the editor's foreground color for diff block text so diffs stay legible in themes where the previous hardcoded color washed them out
- Switch the interface to Inter and Geist Mono
- Fixed: don't discard a successfully refreshed Cline token when the old one was already past expiry, which made the first request after a long idle period fail despite valid credentials
- Fixed: legacy-task migration backlog no longer spams telemetry; migration outcome recorded only once the seeded session persists
- Fixed: involuntary Cline logouts (rejected refresh token) are reported instead of clearing credentials silently
- SDK bundle: Claude Code provider now runs its own native tools, anchors on workspace directory, loads `~/.claude` and project settings
- SDK bundle: truncated tool-call JSON rejected instead of silently repaired
- SDK bundle: strict providers no longer reject turns with empty message content
- SDK bundle: fixed mid-turn crash on streamed tool calls with non-zero indexes
- SDK bundle: token telemetry reports disjoint per-request buckets instead of inflating totals ~5x on cache-heavy sessions
