TC Ore Expose

Added

• Inverse of VeinMiner: when mining near a hidden ore, all cover blocks around the ore vein are broken automatically to expose the ores.
• 3-step processing: identify the ore type, flood-fill same-type ore positions through 26 diagonal directions (corners included, up to 32 blocks), then break surrounding non-ore blocks in rings.
• Trigger setting: Always or Sneak Only (default). Sneak while mining to expose ores, mine normally otherwise.
• Scan radius setting: 1 (3x3x3) or 2 (5x5x5).
• Thickness setting: 1 ring (blocks touching the ore, corners included) or 2 rings (one extra outer ring).
• Mode setting: Near Ore (default), On Ore Break, Both.
• Pickaxe gate: expose only runs while holding a pickaxe in the main hand.
• Custom command /tc:expose with 12 subcommands, works without enabling cheats.
