v2.1.0

• Fixed a crash when clicking a rollable custom ability: this module's
  injected HTML used data-action="rollAbilityCheck" on custom ability
  labels, but that HTML lives inside the DCC actor sheet's own DOM - Foundry's
  ApplicationV2 action dispatch is one delegated listener per sheet matching
  any [data-action] inside it, and DCC's own sheet already has a
  rollAbilityCheck action registered. Every click double-fired: our own
  handler, and DCC's native one, which then crashed trying to read core
  ability data for a field that isn't one. Renamed to a non-colliding
  data-customizer-action attribute (also applied to the Counter/Resource
  +/- buttons for the same reason, pre-emptively).
• Fixed rollable abilities with a stat/save Source crashing with
  "Die is not defined": game.dcc.DCCRoll.createRoll accepts a plain
  formula string, but that code path in the installed DCC system has a bug
  referencing an undefined Die global. Switched to passing a proper array
  of term descriptors instead (which doesn't hit that code path) for
  stat-sourced rolls; Custom Formula rolls bypass DCCRoll's modifier dialog
  entirely and evaluate through a plain Roll instead, since a freeform
  formula was never mechanically compatible with that path in the first place.
• Added a "Rollable" option to custom abilities (both Custom Ability and
  Current/Max types): a Roll Name, a Source (the ability's own value/mod, one
  of the six core ability mods, one of the three saves, or a freeform custom
  formula), and a Roll Under option that mirrors DCC's own Luck check (a
  naked d20 compared against the score, instead of d20+modifier). Uses the
  same game.dcc.DCCRoll API and modifier dialog real DCC ability checks
  use, so rolling a custom ability behaves like rolling a real one -
  including respecting Ctrl-click and the "show roll modifier by default"
  setting. Custom Ability fields were always unconditionally rollable before
  this existed; that behavior is preserved by default for anything saved
  before this update.
• Increased the config dialog's default window size (900x750, up from 700x600).
• Added three new panel field types: Resource (Current/Max with +/- buttons on
  Current only, clamped between 0 and Max; GM sets a Default Max per field), Choice
  (a GM-defined dropdown, one option per line), and Toggle (a simple checkbox).
• Migrated the configuration dialog from the legacy FormApplication/Dialog API
  to ApplicationV2/DialogV2, ahead of Foundry removing the legacy Application
  framework. Raised compatibility.minimum to 13.
• Fixed custom abilities and panels not rendering correctly on NPC sheets. Custom
  abilities now appear as a dedicated row on NPC sheets (DCC's NPC template has no
  ability-scores area to inject into like PC sheets do), and custom panels/separators
  are now correctly styled on NPC sheets (previously inserted into the DOM but
  invisible due to a CSS scoping mismatch with DCC's own NPC template).
• Added an "Applies To" (Both / PC Only / NPC Only) option per custom ability and per
  custom panel, so a GM can scope a custom field to just player characters, just
  NPCs, or both. Existing configurations are unaffected — anything saved before this
  option existed continues to render everywhere, exactly as before.
• Fixed the config dialog rendering with unreadable pale text on white card
  backgrounds under Foundry's dark UI theme.
• Replaced the auto-generated ID shown for each custom ability with an editable
  Roll Key (e.g. sanity), validated for uniqueness and against DCC's own
  reserved roll-data words (str, hp, ac, etc.). The internal storage ID is
  unchanged and keeps owning each actor's saved values — only the roll-formula-facing
  key is renameable. Abilities saved before this feature existed get a suggested key
  auto-filled from their label the next time the config dialog is opened.
• Fixed roll data for custom abilities actually being keyed by their Roll Key
  (previously the unusable auto-generated ID, so @sanityMod-style formulas never
  really worked). Also fixed Current/Max abilities exposing the wrong property in
  roll data (.value was always reading undefined and defaulting to 10 instead of
  the actual current value).
• Removed the prepareDCCActorRollData hook listener — confirmed dead code, DCC
  never fires a hook by that name. Roll data injection now happens solely through
  the getRollData() wrapper, which is what was actually running all along.
• Panel fields no longer show their internal ID in the config dialog (they aren't
  usable in roll formulas, so it served no purpose). Added a one-line description
  for each ability/field type in the config dialog.
• Reworked the config dialog's stylesheet to stop hardcoding its own colors and
  instead rely on Foundry's native theme (the same --color-*/--input-*/
  --button-* variables every other Foundry dialog uses), so it now matches
  Foundry's actual look (light or dark) instead of a fixed white-card style.
  Also fixed the dialog's content area not growing to fill a resized window:
  it's now an explicit flex layout with width: 100%, and the two scrollable
  sections share available height instead of stopping at a fixed pixel cap.
• Reworded the Current/Max field-type description to use Sanity (an ability
  without a modifier) as the example instead of HP.
• Renamed the "Stepper" field type to "Counter" in the config dialog and docs -
  display label only, the internal type value is unchanged, so existing panel
  fields of this type and their saved values are unaffected.
