docs(agent-skill): say the skill is on by default and stays out of git

Every place that called the Codeman Agent Skill setting off by default now
says it is on by default since 1.50.0, where to turn it off, and that turning
it off still removes no copy already written (`codeman skill uninstall --case
<name>` does). The README, the wiki's Codeman Skill page and the FAQ say an
agent inside Codeman usually has the skill without an install step, and that
the copy ignores itself in git.

Also written down: an install whose App Settings were saved on an earlier
version stored the old default and stays off until switched on; with the
Claude Code plugin installed, Claude Code lists the skill twice (both work);
and, in the invariants, the self-ignoring `.gitignore` rules and the
measurement that Claude Code 2.1.319 never runs `git check-ignore` on a skill
folder. The agent control plan keeps its original default-off decision and
gains a dated note for the flip.
