Bow Mechanics Overhaul

Bow Mechanics 1.0.2

• Added Crossbow support! Left-click loads, release fires once loaded.
• Smooth FOV easing when aiming (finally uses zoomSpeed).
• Look sensitivity scales with the zoom while aiming.
• Draw-strength meter under the crosshair.
• Rising draw sound with a distinct full-draw cue.
• Camera kick on release, scaled by draw strength.
• Client enabled toggle, plus a server-side one pushed to clients on join.

Bug fixes: 

• The server trusted the client's reported charge time, so a modified client could get full-power arrows instantly. The server now times each draw itself and caps the shot at what it measured.
• Crossbows were being given bow animations, which overrode vanilla's load and point poses, they now use vanilla poses! There's some limitation so will hopefully find a workaround soon.
• zoomSpeed was declared but never read

Changes:

• zoomSpeed default 0.08 → 0.25 (it's now an easing factor).

Existing config files aren't rewritten, so the new options won't appear until you delete config/bow-mechanics/bow-mechanics.json5. Defaults apply in the meantime including the old 0.08 zoom speed, which will feel sluggish.
