Exclude integrations/ from the source-agent scan (it's convert.sh output) (#593)

#592 added `integrations` to AGENT_DIRS in convert.sh and lint-agents.sh and to
the lint workflow paths, to make those lists match divisions.json. That was
wrong: integrations/ is not a source-agent category — it's where convert.sh
WRITES per-tool conversions (e.g. openclaw output → integrations/openclaw/<agent>/SOUL.md).
It holds 957 conversion outputs across openclaw/opencode/qwen/antigravity, vs
248 real source agents in the 17 genuine categories.

Scanning integrations/ as source made the toolchain re-convert its own outputs:
the same agent appears under every tool (brand-guardian ×5), output slugs
collide, and convert.sh's last-writer-wins corrupts the catalog — which broke
downstream parity checks. convert.sh originally omitted integrations on purpose;
#592 misread that deliberate exclusion as drift.

Fix: drop integrations from convert.sh / lint-agents.sh AGENT_DIRS and the lint
workflow, remove it from divisions.json (it's not a division), and add it to
NON_DIVISION_DIRS in check-divisions.sh so the guard's canonical set is the real
17 source categories. The `strategy` additions from #592 were correct and stay.

check-divisions.sh now PASSES at 17 divisions consistent across divisions.json,
directories, scripts, and CI.

Note: integrations/mcp-memory holds 2 real source agents stranded in the output
tree; relocating them to a real category is left as separate follow-up.
