Adjustability 0.5.0

Added

• Switching tutorial: a persistent book-icon reminder when a dormant item reaches your inventory, then a timed Cycle
  reminder after your first successful panel switch. Progress stays on your client across worlds;
  /adjustability tutorial restarts it. New player section [hints].

• A magenta corner marks inventory slots holding dormant or switched-off enchantments. Player settings slot_marker
  and slot_marker_color control it; slot checks are cached until the item's custom data changes.

• Adjust panel styles: the mark in front of each row can be a circle (as before), square, checkbox, toggle switch,
  radio button or none, and animates when an enchantment switches. Every color and size the panel used to hard-code is
  now a setting: title, row and cost-line colors, text shadow, padding, row height, the line between groups or a
  heading with each group's name (like Mining), row order, where the None row goes, and the item's icon next to its
  name. New [panel.marks], [panel.text] and [panel.layout] sections; older files keep their values.

• Border styles: GRADIENT (as before), SOLID, NONE, or SPRITE, a GUI sprite resource packs can replace.

• Panel profiles: magenta (the defaults), vanilla, minimal and high_contrast built in, plus JSON files in
  config/adjustability/panel_profiles that modpacks ship or /adjustability panel save <name> writes. Apply one with
  /adjustability panel profile <name> or the YACL screen's buttons. default_profile makes /adjustability panel reset go back to a modpack's look.

• Share codes: /adjustability panel export copies a short code for your look, /adjustability panel import (from the
  clipboard, or with the code) or YACL's Paste Code applies one. Every value is checked; what doesn't fit is skipped.

• The YACL screen shows the panel's sections as their own groups, picks the row mark from a list, and its preview shows
  two groups.

• Java API: AdjustabilityClientApi.registerRowMark lets other mods add row marks (client side, experimental).

• A panel styles docs page with a picture of each.

• Switch off any enchantment that conflicts with nothing (Knockback, Fire Aspect, a lone Silk Touch) and back on: the
  Adjust panel opens on any enchanted item and lists them under Other enchantments, one on/off row each, in a
  section that folds. Off stays off through anvils and repairs; the tooltip says (off). Server setting
  allow_switch_off (on by default), player setting singles. Curses never.

• API: switchedOffEnchantments, flatten(stack, registries) (turns switched-off ones back on);
  SwitchResult.SWITCH_OFF_NOT_ALLOWED. /adjustability toggle and inspect know switched-off enchantments.

Changed

• The key hint now says "Left Alt: switch enchantments", with a magenta key and plain gray text directly after the
  enchantment lines. The root advancement's description names your actual Adjust binding.
• AdjustabilityApi.dormantEnchantments no longer includes switched-off enchantments; flatten(stack) is deprecated.
• /adjustability flatten switches switched-off enchantments back on instead of removing them.

Fixed

• Left Alt didn't close the Adjust panel when the cursor was over an empty slot (the panel often covers one).
• A dormant enchantment whose mod or datapack was removed is kept on the item instead of being dropped by the next
  switch, anvil use or repair; it works again if the enchantment comes back. Ignored until then, listed by
  /adjustability inspect and in advanced tooltips (F3+H), removed by the grindstone and flatten.
