fix: restore JSONL fallback when Dolt is unavailable

readIssuesFromDisk was throwing when Dolt was unreachable instead of
falling back to .beads/issues.jsonl on disk. This broke the app for
users without Dolt installed.

Restores the JSONL fallback path: try Dolt first, then read from the
git-tracked JSONL file, return empty array if neither is available.

Fixes #22
