refactor(bin): make caveman hand-invoked only

Sets `disable-model-invocation: true`, so the host withholds caveman from
the model-visible skill listing. It stops paying preload tax and can only
be reached by typing /caveman.

The reason is not the 287 characters. caveman's description was almost
entirely a trigger list -- "caveman mode", "talk like caveman", "less
tokens", "be brief" -- and "be brief" is a false-positive magnet: a user
asking for brevity wants short answers, not dropped articles and
`Respond terse like smart caveman`. Removing the skill from the router
deletes the bad trigger. User's call, made explicitly.

Safe to flag because the flag also hard-blocks the Skill tool, so any
inbound route from another skill would break. Re-checked all 39
descriptions and bodies after four waves of retrofit rewrites: every
mention of caveman is documentation, research notes or the lockfile.
Nothing routes to it.

The description is rewritten as human-facing text, since it is no longer
a routing surface -- it now says how to turn the mode on and off rather
than listing phrases for a reader that can no longer see it.

The two remaining SUGGESTIONs are #108: the boundary-clause check fires on
hand-invoked skills, which ADR-0020 contractually exempts. Advisory, and
not to be "fixed" in the skill.

Preload tax 10,002 -> 9,732 chars across 37 model-visible skills.
