Improves icon clarity on high-resolution displays while preserving the existing artwork. Adds folder renaming, including the default folder.

When the five-link free limit is reached, Burrowmarks now keeps the attempted sixth link ready inside the encrypted vault. After a lifetime license is activated, that pending link is saved automatically. Existing links, deletion, recovery, and export remain available without payment.

Adds multiple independently locked vaults, unlimited free folders, per-vault themes, and a five-bookmark free limit shared across all vaults. Also includes folder deletion, redesigned Mossy, Firefox, Cyber, and Retro appearances, streamlined settings and backup tools, recovery checkups, improved locked-vault screens, and unified Firefox-native icons.

Improved the pinned Firefox toolbar icon for clearer visibility in light and dark browser themes.
