feat(ios): demote the four ios skills to preamble-tier 2 (Phase 5)

They never consume the tier-3 sections (repo-mode ownership, search-before-
building) but do fire AskUserQuestion, which tier >=2 provides — verified by
grep before the plan review. -2.2KB per skill. Render assertions pin the
demotion (tier-3 sections absent, AUQ format present).

## Repo Ownership — See Something, Say Something
`REPO_MODE` controls how to handle issues outside your branch:

Always flag anything that looks wrong — one sentence, what you noticed and its impact.

Before building anything unfamiliar, **search first.** See `~/.claude/skills/gstack/ETHOS.md`.
