v0.7

• added task sequence support in NPC state (task type, target, amount) scoped per player
• added chat parsing for chained tasks (first... then...) and compact mining forms (mine X and Y)
• enforced strict sequential execution: next task starts only after previous one succeeds
• added failure handling for sequence tasks with player-facing error notifications and stop-on-fail behavior
• changed chained mining flow to deliver gathered resources only after the full sequence is completed
• updated help mining text to include new task-sequence syntax and examples
• improved non-treechop harvesting of irregular trees by tracking and processing connected logs
• fixed non-treechop tree-count behavior to cut full trees while returning requested log count
• constrained scaffold behavior to self-placement only and only with standable blocks (saplings excluded)
• added obstacle clearing before scaffold placement (e.g., flowers) when placement/stand space is blocked
• added scaffold placement pacing and incremental cleanup of no-longer-needed temporary blocks
• improved log detection behind leaves by selecting nearest valid logs and ignoring NPC temporary scaffold blocks
