The four document skill names were code in the contract, the hint for
binary files kept its own list of formats and libraries, and the chat
boundary rewrote the old arguments of one add-on by its ID.
A skill that shadows a name can now declare the slot it serves: kind,
file extensions, name words and a library hint. A tool can declare
legacyArgs, the arguments it refuses now, each with a hint. Both need
manifest api 2. The four default slots move to a data file that the
contract reads, so a manifest that declares nothing keeps working.
The host takes the replaceable names, the files a skill covers and the
hint for a script from the skills the add-ons list. It compares no
format or add-on ID. A guard spec fails when it does again. The Office
manifest declares its slots and legacy arguments and accepts api 2.

A tool that shadows bash can now declare an execution descriptor: its
class, a title and a note for the model, and the skill kinds whose
runtime it supplies. The host reads it to build its text and to decide
which skills need isolated execution, instead of knowing add-on IDs.
The field is optional and needs manifest API 2. The host now speaks
API 2 and still accepts add-ons that declare only API 1, so manifests
that declare nothing new keep working unchanged.
