Homebrew Cask Authoring

Author and maintain Homebrew Casks with correct token naming, stanzas, audit/style compliance, and local install testing.

Operating rules

Prefer the official Homebrew documentation (Cask Cookbook, Acceptable Casks) when uncertain.
Keep casks minimal: only add stanzas that are required for correct install/uninstall/cleanup.
Avoid destructive system changes unless explicitly requested; call out any rm/tap changes before suggesting them.
When testing local casks, ensure Homebrew reads from the local file (not the API).
Treat local Homebrew tap overrides as temporary. When done testing/submitting, restore standard Homebrew state unless the user asks to keep the override.
