Fix symlink path resolution in findDatabaseInTree

Resolve symlinks in working directory before walking up the tree
to find .beads directory. This ensures consistent path handling
when repositories are accessed via symlinks.

Without this fix, daemon operations can fail with 'operation not
permitted' errors when trying to export to JSONL, because the
daemon resolves paths differently than the CLI commands.

Example issue: /Users/user/Code -> /Users/user/Documents/Code
The daemon would try to write to the symlinked path while the
file system expects operations on the resolved path.
