refactor(monkeyd): port the crawler in-tree and drop the submodule

The monkeyd-crawler repository moved into tiennm99/mttools, so recursive
clones of the old submodule URL fail and block every deploy. The crawler,
PDF renderer, and export flow now live under internal/modules/monkeyd,
trimmed to the bot's use: a fixed phone page, the bundled font only, and
the font size as the single export option.
