Problem:
- When dbPath is set to relative fallback (".beads/beads.db"),
findJSONLPath() returns a relative path
- daemon_sync_branch.go calls filepath.Rel(absolutePath, relativePath)
which fails with: "Rel: can't make .beads/issues.jsonl relative to ..."
Solution:
- Canonicalize dbPath at assignment in main.go:471 (source fix)
- Add defensive guard in findJSONLPath() (defense-in-depth)
- Use utils.CanonicalizePath() for OS-agnostic handling
(symlinks, case normalization on macOS)
Testing:
- Add TestFindJSONLPath_RelativeDbPath (tracer bullet for bug)
- Add edge case tests for BEADS_JSONL and empty dbPath
- All sync mode tests pass including daemon E2E
