Fix: Use dynamic JSONL path in daemon sync branch operations (#361)

Fixes #359

The daemon's sync branch logic was hardcoding the JSONL path to .beads/beads.jsonl, ignoring the dynamic discovery logic used elsewhere. This caused sync failures in repositories where the JSONL file has a different name (e.g., beads.base.jsonl, issues.jsonl).

Changes:
- Updated cmd/bd/daemon_sync_branch.go to use findJSONLPath() instead of hardcoded path
- Implemented relative path calculation for correct worktree placement
- Applied fix to both push (sync to worktree) and pull (sync from worktree) operations

This works together with PR #360 to fix team/protected branch sync issues.
