feat: add GIS division with 13 specialized agents across 4 tiers (#572)

* feat: add GIS division with 13 specialized agents across 4 tiers

- Strategic: Technical Consultant, Solution Engineer
- Core: GIS Analyst, Spatial Data Engineer, Geoprocessing Specialist, QA Engineer
- Emerging: GeoAI/ML Engineer, BIM/GIS Specialist, 3D & Scene Developer,
  Spatial Data Scientist, Drone/Reality Mapping
- Delivery: Web GIS Developer, Cartography Designer

Also:
- Add Smart Campus Digital Twin use case scenario
- Update agent counts (218→231) and division counts (15→16)
- All agents follow existing format: frontmatter + identity + mission + rules + process

* Wire gis/ division into toolchain + reconcile roster

The PR added the gis/ agents + README rows but didn't register the
division where the toolchain looks, so the 13 agents would be silently
skipped by convert/install/lint. Register gis (alpha: after
game-development) in:
- scripts/convert.sh AGENT_DIRS
- scripts/install.sh AGENT_DIRS + ALL_DIVISIONS + division_emoji (🌍)
- scripts/lint-agents.sh AGENT_DIRS
- .github/workflows/lint-agents.yml (paths trigger + changed-file globs)

README: count 231 -> 232 / 16 divisions and add the Strategy Duel Agent
roster row (reconciles the row #390 left out), so rows == count == 232.

Verified: lint PASS, convert generates all 13, `install.sh --list teams`
shows "gis 13 agents", roster drift 0.
