Veinminer - Highly Configurable

3.1.0\n### New:\n- Optional exhaustion cost for vein mining (disabled by default) with Exhaustion.enabled and Exhaustion.scale in GeneralConfig.toml (1.0 = vanilla per-block cost).\n- Admin commands for exhaustion: /veinminer settings exhaustion enable|disable, /veinminer settings exhaustion scale <value>.\n- Vein-mined blocks now increment vanilla mined-block stats (Fabric uses Stats.MINED, NeoForge uses Stats.BLOCK_MINED) so external stat trackers reflect vein mining.\n- Interactive /veinminer setup wizard (admin-only) with clickable chat buttons covering enable/disable, crouch requirement, block limits, cooldown, exhaustion + scale, durability guard, particles, and block list mode.\n- Admin login prompt (clickable Yes/No) offering to run /veinminer setup until dismissed or accepted.\n### Changes:\n- /veinminer settings output now shows exhaustion enabled + scale.\n- Added /veinminer help setup topic entry.\n- Setup wizard UI restyled (colored headers/buttons, spaced nav row) and clears chat between steps; durability guard and particles now use multi-step flows (enable -> mode/value and enable -> duration/color).\n- Block list mode buttons/command remain whitelist/blacklist, but now honor the separate block-per-tool toggle: config writes blockListMode = WHITELIST|BLACKLIST plus blocksPerTool = true|false and still loads legacy GLOBAL_*/PER_TOOL_* values.\n### Fixes:\n- N/A
