* fix: use official Homebrew cask installation guidance
* docs: guide localized pages through the old Homebrew tap
The translated getting-started pages documented the official cask but not
the migration from the archived tap, so readers of those pages had no
uninstall step for the old formula.
Document current public contracts and implemented workflows, correct invalid editor and slot examples, and distinguish supported font, recovery, and library behavior from remaining gaps.
New top-level nav section documenting OpenPencil's programmability:
- CLI: inspecting, exporting, analyzing, scripting (eval)
- JSX Renderer: elements, style props, visual diffing
- MCP Server: moved from Reference (setup + tool list)
- AI Chat: setup, 87 tools, example prompts
- Collaboration: room sharing, cursors, follow mode
Restructured sidebar:
- Programmable added to nav bar (7 locales)
- Context Menu moved from User Guide to Reference
- MCP and eval-command removed from Reference
