refactor: replace merodi.extensions with enable/disable API

Author: pi66
Date: 2026-09-10 21:19
commit: 4f4d542f

merodi.extensions.X relied on bare field access as a statement,
which is invalid Lua and only appeared to work accidentally.

Replace the extensions table with callable enable/disable APIs:
merodi.enable.X() and merodi.disable.X(). Add ParsersOption to
Lua so enable can handle parser options and inline/block parsers,
not just Goldmark extensions.

Remove registerExtensions/extensions.go and its example.
