Groundworks

First release on Modrinth and CurseForge. Groundworks now works on its own in a vanilla game, with no other mod.

• Placement preview. Holding stairs, slabs, logs, doors, rails and other blocks that depend on how you place them shows a translucent preview of what a click would put down: blue where it replaces a block, red where it would be refused.
• Rotate. R turns the next placement a quarter turn, Shift+R turns it back. With nothing in hand that places, R turns the block you aim at in place.
• Raise and Lower. G and B move the next placement one block up or down, so you can place in mid-air.
• Stretch. Sneak-click stairs, slabs, fences, walls, panes, logs or rails to start a line, sneak-click to add a corner, click to lay it. Stairs climb as a staircase, rails slope, fences connect, and the preview shows each block joined as it will stand.
• Columns. Ladders and chains stretch straight up or down: sneak-click to start, G or B to set the height, click to lay. Your reach doesn't limit the height.
• Dismantle. Sneak-click a fence, wall, iron bar or rail with the tool that breaks it, then click another of the same kind: everything joined between them comes up into your inventory.
• Pack developers: every feature's reach is a tag you can change with a datapack: groundworks:plan_opt_in, groundworks:rotates_in_place, groundworks:stretches, groundworks:stretches_vertically and groundworks:dismantle_family/*.
