NotMines v1.0.1

This update adds PlaceholderAPI support and improves stats database startup reliability.

What's new

• Added PlaceholderAPI support with automatic %notmines_...% stat placeholders
• Added raw numeric placeholder variants for leaderboard plugins like Topper
• Improved SQLite startup handling with a safe fallback when WAL mode is unavailable

Notes

• PlaceholderAPI is optional and only hooks in when installed
• For leaderboard sorting, use the raw placeholders such as %notmines_profit_raw%
