Built-in Feature Packs

Use one table to locate the purpose, dependencies, and source entry point of each built-in Feature Pack.

Built-in packs are split by protocol and site capability. When locating a problem, confirm the input type first, then jump into the matching source directory.

Release Difference

The repository still contains jack_yao, but deploy.py currently keeps it in FEATURE_PACK_BLACKLIST, so it is not shipped in official release packages.
