Removehud v1.4

This project has been inactive for a long time. Honestly i've had no motivation and no time to keep working on Minecraft mods. But i've been going through my AI psychosis recently and it has finally allowed me to take on projects that i would not dedicate much time to normally.

With that said: this project is finally in the place that i've always wanted it to be. Since day 1 of the mod i've dreamed of making a fully featured HUD editor for minecraft. Frankly im not sure why it hasnt been done before to my knowledge. Well finally it's here thanks to claude code.

Summary

Two pieces of work,

1. Ports the mod to Minecraft 26.2 — Mojang's current release, now on date-based versioning.

2. Rebuilds the in-game HUD editor that was abandoned, half-finished, and buggy on origin/unstable-editor-1.21.

Note: since main never received the intermediate 1.20.2 → 1.21 → 1.21.4 bumps, this PR also carries that history forward as part of the diff — it's not new work, just previously un-merged.

Other changes:

• Added a LocatorBar toggle for the new waypoint locator bar (new HUD element introduced in newer MC version, in the same subsystem the mod already manages) — for config parity with the other contextual bars.
• CI (build.yml) bumped to Java 25.

HUD editor Details

What's in this version instead:

• F6 toggles an in-world overlay edit mode while gameplay continues normally, so the full HUD renders exactly as usual underneath the editor's highlight box — this was the previous version's core failure mode, and it's now impossible by construction.
• Anchor corners actually work. Every offsettable/food/air bars, exp bar, held-item tooltip, overlay ent, Shift+Tab cycles its anchor corner, arrow keys nudge it (Shift = 5px steps vs 1px), N toggles offset snapping, R resets the selected element, H shows/hides the on-screen controls hint.
• Snap-to-zero double-tap. With snapping on, an element resting at exactly 0 needs a double-tap to move away from center (a single tap alone would just get immediately re-clamped to 0) — first tap shows a toast hint, second tap within the window jumps it clear of the dead zone.
• Hints render as Minecraft toasts.
