Crosshair Corsair

Rebuilt for Minecraft 26.3.

• The reacharound stops competing for the click. Vanilla tries both hands, so a block in one of them used to jump the queue ahead of a bow, food or an ender pearl in the other; now neither hand holding something with a use of its own lets the reacharound near the click.
• Where the block would land somewhere other than the outline says - scaffolding climbs to the top of its own stack rather than sitting beside it - there is no reacharound at all. An outline that lies is worse than no outline.
• Every held-item setting takes all four words, everywhere: always, targeting (something is under the crosshair), interactable (this item would do something to it) and never. Some took only two before, so a tightening in the menu could deliver a loosening.
• A shield takes the crosshair only when a click would actually raise it - in your main hand, or in your off hand with the main one empty - so sword and board still reads as the sword.
• The attack indicator keeps vanilla's own terms and keeps showing while the crosshair is hidden: it is about your weapon's cooldown, not about what you are pointing at. F3's 3D crosshair stands this mod down entirely, and spectators get vanilla's element untouched.
• The config file rewrites itself whenever it is missing a key, so a setting added by an update is never left hidden in an old file.
