CoC 7e Skill Development

  Automates end-of-scenario skill improvement checks for the Call of Cthulhu
  7th Edition system. For every skill flagged for development it rolls 1d100;
  on a roll greater than the skill's current value it adds 1d10 percentiles
  (capped at 99), clears the development flag, and posts a summary to chat.

  Features:
  - One click processes every development-flagged skill on an investigator.
  - Two entry points: a button in the investigator sheet header (single
    actor), and a bundled macro that opens a GM multi-select picker to batch
    the whole party.
  - Anti-cheat: commit-on-roll by default — a player's rolls are written the
    instant they're made, preventing cancel-and-reroll fishing. The GM keeps a
    confirm/discard review step for legitimate corrections.
  - Configurable result visibility: public, player + GM, or GM-only.

  Requires the Call of Cthulhu 7th Edition (CoC7) system. Foundry v13+.
